In 1968, signs of seepage problems within Wolf Creek Dam's earthen embankments and foundation were discovered. Sinkholes appeared at the downstream toe of the dam, and muddy water was observed in the dam's outflow channel. The seepage problems were traced to the karst geology of the region which allows for the dissolution of limestone in the dam's foundation.

When the seepage velocity is great enough, erosion can occur because of the frictional drag exerted on the soil particles. Vertically upwards seepage is a source of danger on the downstream side of sheet piling and beneath the toe of a dam or levee. Erosion of the soil, known as "soil piping", can lead to failure of the structure and to sinkhole formation. Seeping water removes soil, starting from the exit point of the seepage, and erosion advances upgradient.

In December 1946, the tunnel was shut down and work was begun to remediate the leakage. The tunnel was lined with concrete varying from 19 inches to 6 feet (1.8 m) in thickness. The seepage was temporarily reduced, but pressure again built up and the seepage then increased. By the end of 1947, the MWD and the San Jacinto River Conservation District (formerly the San Jacinto River Protective Committee) agreed that it was impossible to completely stop the seepage.

The main purpose of the twin dikes is to prevent any sea water seepage into coastal reservoir as its water level is below the sea water level. The water level between the dikes is always maintained up to 1 m above the sea level by pumping fresh water from the coastal reservoir to the 1000 m gap between the dikes. The higher level water barrier between the two dikes fully eliminate any sea water seepage in to the coastal reservoir by establishing fresh water seepage to the sea.

A cross section showing the water table varying with surface topography as well as a perched water table If fluid pressures in a soil deposit are uniformly increasing with depth according to u = \rho_w g z_w then hydrostatic conditions will prevail and the fluids will not be flowing through the soil. z_w is the depth below the water table. However, if the water table is sloping or there is a perched water table as indicated in the accompanying sketch, then seepage will occur. For steady state seepage, the seepage velocities are not varying with time.

At a private bridge approximately upstream of Green Cove Road, the peak annual discharge has a 1 percent chance of reaching 430 cubic feet per second. A mid-20th-century report estimated the volume of surface seepage into mine workings at Hull Creek was 9.53 gallons per minute per inch of rainfall. The rate of streambed seepage in the area was estimated to be 17.02 gallons per minute per inch of rainfall. The rate of seepage is much higher than a number of other streams in the area.

This observation was supported by gas capture data recorded by two sea floor tent structures that covered one large seepage area. Surveys continued over the 1990s and 2000s using more sophisticated sonars including chirp and multibeam sonars. These repeat sonar surveys did not detect further decrease in seepage, while during the same period oil production continued.

At this time the lake was becoming increasingly diluted, due to the seepage of these same life- giving irrigation canals. The City Council petitioned the Department of the Interior to remedy this situation. The Bureau of Reclamation built several wells and pumps to intercept the seepage water, and the end of the 1950s diminished the dilution.

A plan flow net to estimate flow of water from a stream to a discharging well Darcy's Law applies in one, two or three dimensions. In two or three dimensions, steady state seepage is described by Laplace's equation. Computer programs are available to solve this equation. But traditionally two- dimensional seepage problems were solved using a graphical procedure known as flownet.

However, it failed to produce economically viable amounts of oil. Alternative methods of digging large shafts into the ground also failed, as collapse from water seepage almost always occurred. The significant step that Drake took was to drive a 32-foot iron pipe through the ground into the bedrock below. This allowed Drake to drill inside the pipe, without the hole collapsing from the water seepage.

The only species of Desmognathus which would be found in the same habitat as the seepage salamander and create competitive pressure is the pygmy salamander (D. wrighti). However, the ranges of the two species rarely overlap. The pygmy salamander is found at higher elevations, while the seepage salamander is found at lower ones. The pygmy salamander is found on the border of North Carolina and Tennessee.

Such coalbed methane capture can reduce the volume of gas seepage that would otherwise occur naturally; while in-turn adding emissions of carbon dioxide once the fuel is utilized elsewhere. Global tracking estimates from the IEA during year 2019 suggest that about 40 millions tons of methane were released from all activities related to coal mining. This total amount includes all vented, fugitive, and seepage emissions.

While the upstream interface between the embankment section's foot and the old streambed is nominally waterproof, the Karst solution channels far under the mass of the earth embankment section proper, can directly attack the porous and not waterproofed foundation of the earth embankment section of the dam. It is this phenomenon that has occurred and led directly to the seepage problem. A short-term solution of grouting the existing seepage channels was employed immediately; grouting in the dam foundation ran from 1968 to 1970 and is credited with saving the dam. Construction of a long-term solution began in 1975 in the form of a seepage cut-off wall.

The loss in strength due to upward seepage is a common contributor to levee failures. The condition of zero effective stress associated with upward seepage is also called liquefaction, quicksand, or a boiling condition. Quicksand was so named because the soil particles move around and appear to be 'alive' (the biblical meaning of 'quick' – as opposed to 'dead'). (Note that it is not possible to be 'sucked down' into quicksand.

The natural outputs from groundwater are springs and seepage to the oceans. If the surface water source is also subject to substantial evaporation, a groundwater source may become saline. This situation can occur naturally under endorheic bodies of water, or artificially under irrigated farmland. In coastal areas, human use of a groundwater source may cause the direction of seepage to ocean to reverse which can also cause soil salinization.
|
|
The report noted increasing seepage, similar in nature to the seepage that caused the 1965 failure. Plans were advanced in 1984 to build a long concrete wall at the east canal outlet works to evaluate its efficacy. However, in May 1985, operators initiated an emergency drawdown of the reservoir after deciding that the dam was "in very serious distress." With the fast drawdown, slumping appeared on the upstream face.

In poured concrete foundations, cracks and pipe penetrations are the most common entry points for seepage. These openings can be sealed from the interior. Epoxies, which are strong adhesives, or urethanes can be pressure injected into the openings, thus penetrating the foundation through to the exterior and cutting off the path of the seepage. In masonry foundations, interior sealers will not provide permanent protection from water infiltration where hydrostatic pressure is present.
|
|
As leaks were sealed, pressure would build and create a new leak elsewhere. Eventually the seepage was reduced to 540 US gallons per minute (0.034 m3/s), and on October 14, 1939, the San Jacinto Tunnel was completed, well ahead of schedule. As pressure increased over time, the tunnel grouting failed and seepage more than quadrupled. In February 1942, the Riverside County Board of Supervisors renewed its protest against exporting local water.

The seepage salamander is part of the genus Desmognathus and the family Plethodontidae. Like all other plethodontids, the seepage salamander is lungless and respires through its skin and the lining of its mouth. They also have a naso-labial groove and a relatively immoveable lower jaw which allows them to force their way under objects. As with all species in Desmognathus, they have a pale line running diagonally from the eye to the angle of the jaw.

A cold seep (sometimes called a cold vent) is an area of the ocean floor where hydrogen sulfide, methane and other hydrocarbon-rich fluid seepage occurs, often in the form of a brine pool. Cold does not mean that the temperature of the seepage is lower than that of the surrounding sea water. On the contrary, its temperature is often slightly higher. p. 20. The "cold" is relative to the very warm (at least ) conditions of a hydrothermal vent.

Shortly after the lake was reopened, seepage was once again discovered which prevented the lake from being completely filled. The new seepage location was not where the dam's last $3.5 million rebuilding project had taken place. In September 2014, the lake was lowered by 20 feet so that repairs could be made to the recent seeping area. Repairs to the dam were completed in Spring 2015 and the lake was filled to capacity for the first time since 1991.

Borewell digging The tube well casing houses the inlet, cylinder, piston valves and rising main of a "down-the-hole" type hand pump. Casing to support the external surfaces of the borehole against collapse may be needed, either temporarily or permanently, and is often made of PVC pipe, which is both cheap and inert. Seepage down the tube well bore is prevented by the sanitary seal. Seepage from the ground above the aquifer is excluded by the lengths of plain casing.

The critical difference is that due to its slow rate of turnover, groundwater storage is generally much larger (in volume) compared to inputs than it is for surface water. This difference makes it easy for humans to use groundwater unsustainably for a long time without severe consequences. Nevertheless, over the long term the average rate of seepage above a groundwater source is the upper bound for average consumption of water from that source. The natural input to groundwater is seepage from surface water.

Canal Lining Canal lining is the process of reducing seepage loss of irrigation water by adding an impermeable layer to the edges of the trench. Seepage can result in losses of 30 to 50 percent of irrigation water from canals, so adding lining can make irrigation systems more efficient. Canal linings are also used to prevent weed growth, which can spread throughout an irrigation system and reduce water flow. Lining a canal can also prevent waterlogging around low-lying areas of the canal.

In the early years the slurry had a low relative density that led to difficult construction conditions with seepage and sloughing on the northern wall. A drained tailings buttress was constructed against the face of the northern wall. A single ringmain around the dam was not used, contrary to current practice. A return water dam that could accept water from the dam itself was not provided. In March 1993 an inspection noticed seepage on the north wall and it was agreed to stop deposition into compartment 4A.

Texas Parks and Wildlife. Ecological Mapping systems of Texas: West Gulf Coastal Plain Seepage Swamp and Baygall Retrieved 7 July 2020 Baygalls are relatively shallow wetlands that typically form on the terraces of forest slopes or on the margins of floodplains. The characteristics of a bayhead swamp are mostly broad, shallow drains, which can be found near margins of bottomlands and floodplains with little or no drainage. They most often receive a slow, but steady supply of water from seepage at the base of slopes and bluffs.

Problems with the embankment became apparent in May 1964, when part of the backfill slid into the stilling basin downstream, attributed to too-fast lowering of the reservoir level. When the reservoir had filled to 10% of capacity, seepage became apparent at the dam's base, with further seepage observed about below the dam from shale outcroppings. In July 1965 another slide occurred in the area of the stilling basin. A significant leak appeared on September 3, 1965 at the west abutment, starting as a wet spot that grew with time.

The foundation excavations were extended below the original ground surface to remove liquefaction soils that would have made the dam unstable in an earthquake. To minimize foundation seepage through the alluvium, thick cut-off walls of plastic concrete were constructed across the three alluvial channels and excavated at least into bedrock. To reduce seepage through the rock foundation, the entire core width was consolidation grouted and a double-line grout curtain was installed to a depth of approximately . Grouting of the west dam took about two years to complete and required of grout holes.

Different types of fabric used for geosynthetic clay liners. Geosynthetic clay liners (GCLs) are factory manufactured hydraulic barriers consisting of a layer of bentonite or other very low-permeability material supported by geotextiles and/or geomembranes, mechanically held together by needling, stitching, or chemical adhesives. Due to environmental laws, any seepage from landfills must be collected and properly disposed of, otherwise contamination of the surrounding ground water could cause major environmental and/or ecological problems. The lower the hydraulic conductivity the more effective the GCL will be at retaining seepage inside of the landfill.

Roberts (2001) presented a spectrum of responses to be expected under a variety of flux rate conditions varying from very slow seepage to rapid venting. Very slow seepage sites do not support complex chemosynthetic communities; rather, they usually only support simple microbial mats (Beggiatoa sp.). In the upper slope environment, the hard substrates resulting from carbonate precipitation can have associated communities of nonchemosynthetic animals, including a variety of sessile cnidarians such as corals and sea anemones. At the rapid flux end of the spectrum fluidized sediment generally accompanies hydrocarbons and formation fluids arriving at the seafloor.

The water thus available is called primary water supplies / flows in a river. If there is no ground water extraction, over a period of time all ground water aquifers get saturated fully and further ground water percolation to the aquifers would join the river streams as enhanced seepage flows / base flows. Thus any underground water extraction / use from the river basin aquifers reduce the primary water flows in the river basin. When river water is used in surface irrigation, the part of water joining the stream is termed as ‘return flows’ and the part of water joining the aquifer is termed as ‘seepage loss’ or manmade ground water charging.

Jaisalmer Fort (from Sonargadh) The Jaisalmer Fort today faces manifold threats that are a result of the increasing population pressure on it. Water seepage, inadequate civic amenities, derelict houses and seismic activity around the Trikuta Hill are some of the major concerns impacting the Fort. Unlike most other forts, the Jaisalmer Fort has been built over a weak sedimentary rock foothill which makes its foundations especially vulnerable to seepage. Over the years this has led to the collapse of significant portions of the Fort such as the Queen's Palace or Rani Ka Mahal and parts of the outer boundary wall and the lower pitching walls.

Geological evidence demonstrates that hydrocarbon and brine seepage persists in spatially discrete areas for thousands of years. The time scale for oil and gas migration (combination of buoyancy and pressure) from source systems is on the scale of millions of years (Sassen, 1997). Seepage from hydrocarbon sources through faults towards the surface tends to be diffused through the overlying sediment, carbonate outcroppings, and hydrate deposits so the corresponding hydrocarbon seep communities tend to be larger (a few hundred meters wide) than chemosynthetic communities found around the hydrothermal vents of the Eastern Pacific (MacDonald, 1992). There are large differences in the concentrations of hydrocarbons at seep sites.

The contract was signed on February 11, 1937, turning over the entire seepage flow to the three ranchers, with 57 percent going to the Poormans. The pipeline that would carry water from the west portal crossed the Poorman ranch, and a safety blowout (where excess pressure could be released in an emergency) was built on the property where their share was delivered. Other local ranchers and water companies were caught off guard by the settlement. The Nuevo Water Company had been negotiating with the MWD since 1936 to have the seepage water pumped higher up the San Jacinto River where it could be allowed to sink back into the natural water table.

There are two types of seep that can occur, depending on the degree of overpressure. Capillary failure can occur in moderate overpressure conditions, resulting in widespread but low intensity seepage until the overpressure equalizes and resealing occurs. In some cases, the moderate overpressure cannot be equalized because the pores in the rock are small so the displacement pressure, the pressure required to break the seal, is very high. If the overpressure continues to increase to the point that it overcomes the rock's minimum stress and its tensile strength before overcoming the displacement pressure, then the rock will fracture, causing local and high intensity seepage until the pressure equalizes and the fractures close.

Other LID like concepts around the world include sustainable drainage system (SUDS). The idea behind SUDS is to try to replicate natural systems that use cost effective solutions with low environmental impact to drain away dirty and surface water run-off through collection, storage, and cleaning before allowing it to be released slowly back into the environment, such as into water courses. In addition the following features can also be simulated using the features of SWMM 5 (storage ponds, seepage, orifices, Weirs, seepage and evaporation from natural channels): constructed wetlands, wet ponds, dry ponds, infiltration basin, non-surface sand filters, vegetated filterstrips, vegetated filterstrip and infiltration basin. A WetPark would be a combination of wet and dry ponds and LID features.

There were no large changes in the amount of the seepage that was collected and, month after month, the pipe flowed about one-third full. This was an insignificant amount for a dam the size of the St. Francis, and on this subject Mulholland said, "Of all the dams I have built and of all the dams I have ever seen, it was the driest dam of its size I ever saw." The seepage data recorded during the 1926–1927 period shows that the dam was an exceptionally dry structure. On May 27 the problems in the Owens Valley escalated once again with the dynamiting of a large section of the Los Angeles Aqueduct, part of the California Water Wars.

In very old concrete where the calcium hydroxide has been leached from the leachate seepage path, the chemistry may revert to that similar to "speleothem" chemistry in limestone cave. This is where carbon dioxide enriched rain or seepage water forms a weak carbonic acid, which leaches calcium carbonate (CaCO3) from within the concrete structure and carries it to the underside of the structure. When it contacts the atmosphere, carbon dioxide degasses and calcium carbonate is precipitated to create calthemite deposits, which mimic the shapes and forms of speleothems. This degassing chemistry is not common in concrete structures as the leachate can often find new paths through the concrete to access free calcium hydroxide and this reverts the chemistry to that previously mentioned where CO2 is the reactant.

At the Canning in addition to cutting back the foundation to solid unfractured rock, a cut-off trench was sited near the upstream face of the dam, down stream which a rock filled drain containing open jointed pipes was provided to intercept any seepage between the rock face and the concrete of the dam. The inclusion of an internal drainage system was considered innovative at the period. Near vertical tubular 8 in (200 mm) cut-off drains were provided at five-foot (1.52 m) intervals along the dam to relieve internal seepage through the concrete. While state of the art materials-handling methods were used, in some instances labour-saving machinery worked beside operations intended to maximise the labour content.

The substrate, therefore, plays a critical role in the creation of micro-environmental "arid islands." Sand readily store water because it is taken up easily and there is less evaporation except for the top layer. Very deep sand; however, has the problem of seepage. Yet in moderation shallow and deep sand substrates have water available to Pachypodium.

The lower 20 mi (32 km) of the river are within the Paria Canyon-Vermilion Cliffs Wilderness, which is administered by the Bureau of Land Management; a permit is required for any overnight visit. The Paria is essentially a large creek and is not navigable. A 2004 study estimated that the Tropic Ditch, a historic artificial irrigation canal that diverts water from the East Fork Sevier River, loses 1060 acre-feet per year to seepage, and half of that seepage (530 acre-feet per year) ends up in the Paria River, bringing with it 1829 tons of salt per year. To help restore the salinity of the Paria and Colorado Rivers to more natural levels, the Tropic and East Fork Irrigation Company has proposed replacing the last 5.5 miles of the ditch with a pipeline.

When rain falls on the land mass, soil absorbs a part of rain water and remaining part of the rain water joins the nearby stream by flowing on the surface of soil. Some of the water absorbed by the soil gets evaporated from the soil, some part of the remaining water in the soil emerges into the surface stream as seepage flows and rest of water collects in the underground aquifer as ground water. This process also takes place when the land is irrigated by surface water. The surface run off and the subsurface seepage out of the total rainfall is the available water in the river basin after deducting the natural evaporation loss from the naturally formed water bodies (both perennial and non perennial) in the river basin in a water year.

The branching valley networks of Mars are not consistent with formation by sudden catastrophic release of groundwater, both in terms of their dendritic shapes that do not come from a single outflow point, and in terms of the discharges that apparently flowed along them. Instead, some authors have argued that they were formed by slow seepage of groundwater from the subsurface essentially as springs. In support of this interpretation, the upstream ends of many valleys in such networks begin with box canyon or "amphitheater" heads, which on Earth are typically associated with groundwater seepage. There is also little evidence of finer scale channels or valleys at the tips of the channels, which some authors have interpreted as showing the flow appeared suddenly from the subsurface with appreciable discharge, rather than accumulating gradually across the surface.

A concrete overflow spillway on the west side prevents overtopping and drains to the San Antonio and Chino Creek channels, which were lined with concrete between 1956 and 1960 to protect against such an event. A project has been underway since 2012 to remediate seepage problems at the toe of the dam during heavy rainstorms. The dam is considered a high hazard structure.

Most of the lake water comes from groundwater seepage; however, there are also three tributary creeks. Rainbow Creek is a year-round tributary, while Billie Creek and Dry Creek have only seasonal flows. The lake's only outlet flows into Great Meadow, a wetland at the northeast end of the lake. Great Meadow drains into Seldom Creek, which flows into Upper Klamath Lake.

The water industry began using flexible membranes in the 1950s. Advantages over rigid storage systems include low cost, less algae growth, lower groundwater contamination, and less evaporation and seepage. Disadvantages include shorter life expectancy, greater susceptibility to damage, and more frequent maintenance requirements. Due to the structural limitations of flexible tanks, they tend to have a maximum recommended water storage capacity.

Cutthroat grass communities are heavily dominated by the cutthroat grass species. They occur in a number of habitat types, but all are dependent on wildfire for their natural maintenance. Fire keeps the open grassland free of large and woody vegetation. The most distinctive cutthroat grass community is the cutthroat seepage slope, a range of microhabitat types defined by elevation and the water table.

From a navigational perspective, it was generally better to set sail from France before May 1. Ships of the 17th century were generally smaller than , so the accommodations on board were modest. Food would often spoil due to water seepage, and passengers had to settle for cold meals and soggy bedding. Despite all the hardships and perils, most sailors and passengers arrived safely.

Heavy rain three days beforehand caused the local clay to absorb a large amount of water. Only a small amount of evaporation had occurred due to low ambient temperatures. Race officials examined water that emerged through the track's surface in several areas on Thursday. The track surface had been drilled through overnight in an effort to drain collected water and prevent further seepage.

Railways arrived in 1880, bringing Anglo settlers. The federal government encouraged more irrigation, which probably peaked in the early 1890s. The newcomers developed the vineyards, orchards and vegetable farms, and by 1900 were exporting produce as far as California. Over-exploitation caused a steady decline in irrigation due to "droughts, sedimentation, aggradation of the main channel, salinization, seepage and waterlogging".

In 1967, a Japan Air Self-Defense Force training aircraft crashed next to the kofun, causing considerable damage. During the restoration work, numerous haniwa were found, some in the forms of horses, people, waterfowl, etc., in addition to the more common cylindrical varieties. Penetration into the interior of the kofun was hampered by seepage of ground water, and subsequent work was suspended.

Although the new towns were well planned, there was some settler dissatisfaction about the loss of water from seepage. Disputes about the Chaffey's practices were discussed in the Victorian parliament. A collapse of the Melbourne land boom also contributed to problems faced by the Chaffeys. After a government report, the Mildura Irrigation Trust took over from the Mildura Irrigation Co. in September 1895.

Instead, a shift towards consistency of thought on the information from the messages and topics grew stronger as time passed, often referred to as "seepage" of information. The lack of change was reasoned to be due to a persistence in the individual's existing thought processes which inhibited their ability to properly re-evaluate their initial opinion, or as McGuire called it, cognitive inertia.

In the early 21st century, there are concerns related to the dike's stability because studies have indicated long-term problems with "piping" and erosion. Leaks have been reported after several heavy rain events. Proposed solutions to the dike's problems have included the construction of a seepage berm on the landward side of the dike, with the first stage costing approximately $67 million (US$).

Also, some septic tank designs have a second stage where the effluent from the anaerobic first stage is aerated before it drains into the seepage field. A properly designed and normally operating septic system is odor-free. Besides periodic inspection and emptying, a septic tank should last for decades with minimal maintenance, with concrete, fiberglass, or plastic tanks lasting about 50 years.

Uhrig's Cave beer garden, ca. 1870 Several breweries were built atop these natural caves, which were altered to suit their purposes. Stone arches and brick ceilings prevented water seepage and uneven cave floors were paved with brick. In addition to being used for the storage and lagering of beer, such naturally cool places were sometimes employed as beer gardens, places for entertainment.

The village centre was the pub The Dynefor Arms, and the cottages surrounding it. In the seventies, the nearby Brofiscin Quarry was used as a dump for toxic chemicals. The site was described by The Guardian in 2007 as "one of the most contaminated places in Britain". In 2007 research began to assess the potential environmental impact of seepage from the Quarry.

During this excavation, approximately of material was removed. Since the dam was an arch-gravity type, the side-walls of the canyon would bear the force of the impounded lake. Therefore, the side-walls were excavated too, to reach virgin rock, as weathered rock might provide pathways for water seepage. Shovels for the excavation came from the Marion Power Shovel Company.
|
|
The cause of this decrease was unknown but attributed to seasonal variation. While excavating the opening, workers saw seepage at above the bottom of the tunnel; they believed that meant that there was of water backed up in the tunnel. Excavation at the entrance was postponed until 2015, so that a pond large enough to treat that volume of water could be constructed.

On 18 October 2010, after an afternoon review, engineers were asked to double-check the torque on six bolts around the suspected leaky flange fitting and tighten if necessary. Subsequent leak tests showed again signs of seepage, and the task of solving the issue required the draining of both the left and right OMS tanks of the shuttle and a unique in-situ repair at the pad to avoid a rollback. On 23 October 2010, engineers completed the removal and replacement of the two seals on the right OMS crossfeed flange, after the education (a vacuum-related procedure, used to completely clear the plumbing of the toxic MMH) of the plumbing was completed ahead of the schedule by over a day. Later, testing indicated that the new seals were properly seated and holding pressure with no signs of additional seepage.

The major tributaries of the Slough are Tecolotito Creek, Carneros Creek, and Atascadero Creek. Tecolotito Creek's highest flows are during winter storms; during the summer flows are intermittent. Carneros Creek's major flows are of the flash flood type, with intermittent flows in the summer months. Atascadero Creek is a stream that generally has perennial freshwater flow that is augmented by seepage and landscape watering.

Since rehabilitation, it has been found that the tailings repository at the Mary Kathleen site has been subject to seepage of radioactive waters from both the toe of the dam and the surface at rates much higher than initially predicted. The radioactive waste has seeped into former evaporation ponds as well as local drainage systems, causing widespread death of native vegetation. This issue remains unresolved.

Environmental Conservation 9(04), 348. Before this sharp decline in population, Wyoming toads were commonly found in the floodplains, ponds, shallow lakes, and seepage pools within the Laramie Basin located in Albany County, Wyoming. Researchers had noted that the species was found abundantly in the region since 1952. However, starting in 1975, Baxter & Stromberg noticed that the population of the Wyoming toad had decreased significantly.

It blooms most heavily after a fire, and rarely blooms in the absence of fire. This grass grows in seepage bogs on the Lake Wales Ridge and other ridges in central Florida, an area of high plant endemism. It occurs on moist slopes that receive moisture from areas at higher elevation. It may be found near ponds in Florida scrub, or scrubby habitat, and in marshy flatwoods.

Typically, the ponds communicate with the open sea through ground seepage. Evaporation and precipitation cycles in salt ponds create variable environments with wide ranges of salinity and depth. Due to depth and temperature fluctuation salt pond could be classified as hyposaline 3-20 ppt, mesosaline 20-50 ppt, or hypersaline with ppt greater than 50. Another important aspect of salt ponds is their permanence.

The dam site is located upstream of the ruins of the Great Dam. The new dam, like the old, was designed to store water for irrigating the Ma'rib plains. However, the wadi bed at the new dam site consists of alluvial sand and gravel material 30–50 m thick. Seepage that emanates from this dam does not threaten its structure, but results in the loss of water.

Advances in wound care allow for semi- permeable dressing, which allow seepage of blood and tissue fluid, to be applied and changed at least daily. The vulnerable recipient area must be shielded from the sun, and shampooing is started two days after the surgery. Some surgeons will have the patient shampoo the day after surgery. Shampooing is important to prevent scabs from forming around the hair shaft.

The construction of the tunnel was problematic. Unlike the bedrock through which the C&O; carved its western tunnels, Richmond's blue marl clay shrink- swell soil tended to change with rainfall and groundwater, causing cave-ins during the construction. Ten workers were reportedly killed. The tunnel has remained troublesome throughout its life due to ground water seepage and safety concerns, even after abandonment in 1925.

Tests have revealed that the level of the lagoon does not fluctuate with the tide and its level of salinity is low. Fresh water, however, seeps from the lagoon into the sea.Derek Goring, Seepage Through the Wainono Lagoon Gravel Berm, accessed 22 October 2007. The Department of Conservation (DOC) has established the Wainono Lagoon Conservation Area to protect the natural environment of the lagoon.

The Mica Dam in Canada An embankment dam is a massive artificial water barrier. It is typically created by the emplacement and compaction of a complex semi-plastic mound of various compositions of soil, sand, clay and/or rock. It has a semi-permanent natural waterproof covering for its surface, and a dense, waterproof core. This makes such a dam impervious to surface or seepage erosion.

It is situated on the bank of a canal that originates from the Barrage Qadirabad Colony. Most of the land suffers from seepage which make it unsuitable for cultivation. This is the reason many residents have been driven the away from village to either big city for work or converted their lands into fish farms. Presently the village is surrounded on all sides with fish farms.

Pumps were used to pull water from the quicksand while the dam was built. Since the sand would get wet and soft again, the pumps were not a permanent solution. Rather, the dam was designed with ten seepage pipes that drain into a drainage tunnel passing through the dam's three spillways. The dam, completed in June 1937, created a reservoir and was well received by local residents.

A collection of blood (or even a hemorrhage) may be aggravated by anticoagulant medication (blood thinner). Blood seepage and collection of blood may occur if heparin is given via an intramuscular route; to avoid this, heparin must be given intravenously or subcutaneously. It is not to be confused with hemangioma, which is an abnormal buildup/growth of blood vessels in the skin or internal organs.

His fresco masterpiece from this period is Saint George and the Princess of Trebizond (c. 1433–1438) at the Pellegrini Chapel, church of Sant'Anastasia, Verona. It had to be restored after water seepage badly damaged the fresco at the end of the 19th century. He prepared for this painting with a large number of drawings, many of which are on display in the Louvre Museum, Paris.

This niche is an important nesting and feeding area for many bird species including rails. Since this marsh lacks cordgrass, it is a poor nesting site of ducks. Dense pickleweed provides good habitat for a variety of rodents, reptiles and rabbits. North of the salt marsh of Vicente Creek lies the freshwater marsh and seepage, which hosts a number of trees supporting bird-life and mammals.

Covering only , Cleawox Lake's drainage basin is separate from the nearby Woahink-Siltcoos watershed to the east and south. Water enters Cleawox from small surface streams and by seepage, and no surface outflow has been identified. Soils are sandy and well-drained and support mainly pines and shrubs. Although the lake is saltier than most other coastal lakes in Oregon, it is also more transparent.

Dissolved matter is invisible, and is transported in the form of chemical ions. All streams carry some type of dissolved load. This type of load can result from mineral alteration from chemical erosion, or may even be the result of groundwater seepage into the stream. Materials comprising the dissolved load have the smallest particle size of the three load types (Strahler and Strahler, 2006).

Bioreactor landfills are a relatively new technology. For the newly developed bioreactor landfills initial monitoring costs are higher to ensure that everything important is discovered and properly controlled. This includes gases, odours and seepage of leachate into the ground surface. The increased moisture content of bioreactor landfill may reduce the structural stability of the landfill by increasing the pore water pressure within the waste mass.

The catchment of the reservoir is 0.72 km² large, with a perimeter of 3.34 km and a length of 1210 metres. The reservoir suffers from rapid siltation. The lithology of the catchment is dominantly Agula shale and little Mekelle dolerite. Part of the water that could be used for irrigation is lost through seepage; the positive side-effect is that this contributes to groundwater recharge.

This displaced bentonite slurry is then channelled to a recycling unit from which it can subsequently be reused in a new trench elsewhere on the construction site. In addition, because the colloid is relatively impervious to water, a slurry wall can prevent the seepage of groundwater, which is useful in preventing the further spread of groundwater that has been contaminated by toxic material such as industrial waste.

They are also the only two terrestrial, direct- developing Desmognathus species. However, the two species are not often seen to coexist, differing in distribution by elevation; although there are exceptions. The seepage salamander is currently listed as Near Threatened, with its numbers declining in most of states in which it is found. It is threatened by habitat loss, with logging having a major effect.

Other areas have more mixed woodland. Within the reserve there are numerous springs and areas with water seepage, with the petrifying springs being one of the most important habitats listed in the EU Habitats Directive. Knocksink Wood has the most diverse woodland invertebrate fauna recorded in Ireland, with a number of animals specific to wet woodland that are of threatened status in the EU.

These sandstones and siltstones were crushed and compacted to form the dam embankment. The embankment also contains approximately of processed basalt. This material was incorporated into various filters and drains within the embankment to cope with seepage within the embankment and foundations. The concrete face which tapers from at the base to at the crest acts as a seal between the water and the dam embankment.

In September 1961, a segment of the first completed section of the bypass, long, was observed to be settling into the ground. Investigation of the matter concluded water seepage underneath the roadbed had caused the settlement. Tanner Construction had completed construction of this section of the bypass a year earlier. Test bores were drilled to find the source of the water intrusion and solve the problem.

The Southern Ute Indian Tribe’s methane capture project has reduced greenhouse gas emissions by the equivalent of about 379,000 metric tons of carbon dioxide between 2009 and 2017. Conventional coal bed methane production wells were not economically feasible in this location due to the low volume of seepage. The project delivers its gas to natural gas pipelines, and generates additional revenue through the sale of carbon offsets.

These operations resulted in pollution of groundwater and soil, with high concentrations of volatile, semi-volatile, and inorganic contaminants. Contaminated water seepage from Thermo-Chem contributed to degradation of the adjacent Black Creek Watershed. Preliminary assessment of the site was completed in August, 1984, and the site was finalized on the National Priorities List in June, 1986. Long-term remediation efforts took place between 1996 and 2000.

Rainwater seeps through the sand but runs into a clay layer where it is either trapped (like a pool) or seeps out the side of a hill. These nutrient-poor, moist sites are ideal for the carnivorous pitcher plants. Bogs common to many "flatwood" longleaf areas are called "wet prairies" while other bogs found on hillsides are called "seepage slopes". The transition from forest to an open bog is not immediate.

There are several streams on the surface, such as Black Creek, Little Black Creek, Hazle Creek, and Cranberry Creek. Besides minepools, contributors to the flow of the tunnel include precipitation draining through mines, seepage of streams, and water falling through sinkholes and cave-ins. 39% of the Jeddo Tunnel's discharge, or per second, comes from the Black Creek watershed. 26%, or per second comes from the Cranberry Creek watershed.

|
This oversteepens the slope and can lead to collapse when the soil dries. Piping failure may occur when high groundwater seepage pressure increases, as well as the rate of flow. This causes collapse of part of the bank. Failure is usually due to selective groundwater flow along interbedded saturated layers within stratified river banks, with lenses of sand and coarser material in between layers of finer cohesive material.

Gabion stepped weirs are commonly used for embankment protection, river training and flood control; the stepped design enhances the rate of energy dissipation in the channel, and it is particularly well-suited to the construction of gabion stepped weirs. For very low flow, a porous seepage flow regime may be observed, when the water seeps through the gabion materials and there is no overflow past the step edges.

The ventilation system maintains the air pressure in the service tunnel higher than in the rail tunnels, so that in the event of a fire, smoke does not enter the service tunnel from the rail tunnels. Two cooling water pipes in each rail tunnel circulate chilled water to remove heat generated by the rail traffic. Pumping stations remove water in the tunnels from rain, seepage, and so on.

Many species are especially known for growing on rock walls around waterfalls and water seepage areas. The highest species diversity is in the Andes. Fairly high diversity also occurs in eastern Asia, with nearly 40 species in China. Species native to North America include A. pedatum (five-fingered fern) and the closely related A. aleuticum, which are distinctive in having a bifurcating frond that radiates pinnae on one side only.

Deposition in a wadi is rapid because of the sudden loss of stream velocity and seepage of water into the porous sediment. Wadi deposits are thus usually mixed gravels and sands. These sediments are often altered by eolian processes. Over time, wadi deposits may become "Inverted Wadis," where former underground water caused vegetation and sediment to fill in the eroded channel, turning previous washes into ridges running through desert regions.

Proven world oil reserves, 2013. Unconventional reservoirs such as natural heavy oil and oil sands are included. Chemist James Young noticed a natural petroleum seepage in the Riddings colliery at Alfreton, Derbyshire from which he distilled a light thin oil suitable for use as lamp oil, at the same time obtaining a more viscous oil suitable for lubricating machinery. In 1848, Young set up a small business refining the crude oil.

The site consists of 12 to 17 sizeable chambers and numerous small floors and galleries, primarily made of limestone. Other minerals, such as aragonite and selenite can be found in smaller quantities. Elements, such as zinc, iron, and sulfur have accumulated in walls. Over the course of 5 Million years, extended periods of water seepage have caused the formation of countless and often very illustrious speleotherms (Stalagmites and Stalactites).

The slackwater darter uses two different, but adjacent, breeding and nonbreeding habitats. Its nonbreeding habitat is small to moderately large streams with a moderate to slow currents. The species seems to prefer bottom conditions characterized by an accumulation of leaves and detritus, but in some areas, it has been found in association with clean silt, sand, and small gravel substrates. Breeding habitat is seepage water in open fields or woods.

The Saddle Dam rises above the lowest point in the Domenigoni Mountains ridgeline of the north rim and is around long. The dam was built to increase the storage capacity of the lake, which would have been limited due to the lower ridge in this area. It is founded completely on phyllite and schist bedrock. To minimize foundation seepage, a two-line grout curtain extends up to below the foundation.

Its typical habitat has been reported as along creekbanks and seepage areas in eucalypt woodlands. S. velleioides is similar to several other species in section Debilia. It, like S. paniculatum, has a paniculate inflorescence, but differs from S. paniculatum by its longer capsules and column. It can also be confused for S. semipartitum, which has glandular-hairy leaves and scapes whereas S. velleioides's leaves and scapes are glabrous.

Irrigation scheme in Upper Gabat Besides springs and reservoirs, irrigation is strongly dependent on the river's baseflow. Such irrigated agriculture is important in meeting the demands for food security and poverty reduction. Irrigated lands are established in the narrow alluvial plains along the river in many places; the farmers use motor pumps to pump baseflow water generated by seepage from Hiza'iti Wedi Cheber, Gereb Segen and Gereb Bi'ati reservoirs.

The reservoir suffers from rapid siltation. The lithology of the catchment is composed of Ashangi Basalts. Part of the water that could be used for irrigation is lost through seepage; the positive side-effect is that this contributes to groundwater recharge. Actually, in the wider surrounding of the reservoir, both upstream and downstream the level of the watertable has strongly raised, and the area has become remarkably greener.

Upstream of the dam, a series of channels and embankments divert water from the Ayash River from entering the reservoir. This helps the environment and protects the stability of the dam. The reservoir is lined with a geomembrane which controls seepage of tailings into the environment. Water released into the environment is purified to meet standards and discharges from the dam are maintained at at least 150 liters per second.

MacDonald et al. (1993 and 1996) have analyzed remote-sensing images from space that reveal the presence of oil slicks across the north-central Gulf of Mexico. Results confirmed extensive natural oil seepage in the Gulf of Mexico, especially in water depths greater than 1,000 m (3,281 ft). A total of 58 additional potential locations were documented where seafloor sources were capable of producing perennial oil slicks (MacDonald et al.

The lake went completely dry, and the Colorado Division of Wildlife, in concert with Denver Water resurrected it in 2007. The Colorado Division of Wildlife re-stocked the lake with rainbow trout, brook trout, cutbow, cutthroat trout, brown trout, and splake. In 2011, engineers began lowering the water level by two feet due to excess seepage. The dam has leaked since its construction, requiring it to operate under state restrictions.

The slab of material in the lower half of the bank will fall out, leaving an alcove shaped cavity. Failure is usually associated with steep banks and saturated finer grained cohesive bank materials that allow buildup of positive pore water pressure and strong seepage within structure. Popout failure is when small to medium-sized blocks are forced out at or near the base of the river bank due to excessive pore water pressure and overburden.

The city decided to move its government to a new building near the waterfront to revitalize it, and vacated Crooks' building in 1972, a century after it had been commissioned. Over the next two decades the empty building began to decay. Its facades crumbled, and the rich interior became filled with broken glass and rusted metal. The chandeliers had corroded due to water seepage, and the wall plastering was gradually becoming fine dust.

Renovated Window Detail at Shinde Chattri Unfortunately, this memorial was overlooked for several years and was in a bad condition. The structure had gathered moss on the hall, due to the seepage of rain water. Rain and moisture had damaged the upper storey of the building, constructed in yellow stone, which had acquired a grayish look. The roof was also damaged, allowing the rain water to seep into the hall, damaging the carvings.

Approximately of contaminated water had been leaking from the site on a daily basis, leaching into groundwater or washed away in the rain. In 1983, following the construction of a wall constructed around the center of the dump site, seepage was reduced to per day. The contaminated areas at the dump site were also covered with a high-density polyethylene (HDPE) cap. In 1992 a treatment plant was constructed to flush the landfill.

The advantage of this type of device is that it is inserted empty into the vagina and can be positioned around the cervix without risk of seepage of sperm. This device is growing in popularity because its use ensures that the donor's semen is deposited as close as possible to the cervix, and it can be kept there while the woman goes about her normal activities for several hours to aid conception.

Seeps can also contribute to streams. If a stream is flowing below a water table then the stream receives contributions from the ground water via seepage. This allows for a drainage of the ground water along with creating a more substantial stream to flow. The seep could be especially effective during a rain less period of the area in which the seep can actually prolong the stream’s flow by adding water from the groundwater.

The catchment of the reservoir is 9.71 km² large, with a perimeter of 14.24 km and a length of 4960 metres. Due to the possibility to by-pass sediment-laden water, the reservoir suffers from less rapid siltation. The lithology of the catchment is Agula Shale and Mekelle Dolerite. Part of the water that could be used for irrigation is lost through seepage; the positive side-effect is that this contributes to groundwater recharge.

The petitioner, Midland Empire Packing Company (Midland), was the owner of a meat-packing plant in the State of Montana. The basement rooms of Midland's plant were used for the curing of hams and bacon and for the storage of meat and hides. The original concrete walls and floors were not sealed against water. When the water in the nearby Yellowstone River was high, the underground water caused increase seepage in the plant.

The water level loses a maximum of 1.3 centimetres per day through evaporation and water seepage, which equates to 10,000 cubic metres of water. In order to maintain a constant level, a pump station at a series of ponds in Ricklingen provides the Maschsee with a water supply. Its three pumps send water along an pipe to the "source" of the Maschsee. Depending on weather conditions, between 1-2 million m3 of water are required.

Russell, Miller E. (1966) Light on the Hill: A History of Tufts College (1852-1952). Throughout its existence Packard Hall was plagued with structural problems, including moisture seepage and bulging walls. Fire hazard required students to move out in 1901, since wood stoves and fireplaces were not deemed safe for the building. When the library moved out, the building became the headquarters of the Crane Theological School and then the Department of English.

The links in the Transport compartment now also have seepage and evaporation. The Transport compartment contains a network of conveyance elements (channels, pipes, pumps, and regulators) and storage/treatment units that transport water to outfalls or to treatment facilities. Inflows to this compartment can come from surface runoff, groundwater interflow, sanitary dry weather flow, or from user-defined hydrographs. The components of the Transport compartment are modeled with Node and Link objects.

Then World War II interfered: the steel frame was cut in 1941 and 1942 and used for Moscow's defense fortifications and railroad bridges. The empty foundation stood unused, filled with seepage water, but well guarded, until 1958. Meanwhile, Iofan's team, relocated to Sverdlovsk, continued perfecting the design. After the war, Iofan produced another iteration of the original concept, this time incorporating the Victory theme, literally: interior halls were decorated with Order of Victory motifs.

Astylosternus nganhanus occurs along watercourses in a few narrow gallery forests, and in seepage areas in the nearby grassland, at elevations of above sea level. Tadpoles probably belonging to this species have been found in rock pools in streams. This species, known from only a single population, is probably at severe risk from habitat loss caused by smallholder farming activities and subsistence wood extraction. It is not known to occur in any protected areas.

Construction of the Coachella Canal began in the 1930s by the Six Companies, Inc., but was interrupted by World War II. After the war, work was resumed on the canal and deliveries of water began in the late 1940s. The canal was mostly earth-lined when it was first constructed, except for the last 38 miles, which were concrete-lined. Today, most of the canal is lined with concrete to prevent water loss from seepage.

Leaks have been reported after several heavy rain events. Proposed solutions to the dike's problems have included the construction of a seepage berm on the landward side of the dike, with the first stage costing approximately $67 million (2008 USD). Several refurbishment projects occurred throughout the years. More recently, from 2007 to 2016, the Army Corps of Engineers spent $500 million (2016 USD) on improvements, including building of a reinforcement wall inside the dike.

The brewery is built upon a complex of natural caves which were once used for the lagering of beer by early German brewers. Caves are naturally cool, which was especially attractive to brewers before the advent of refrigeration.Milestones of Missouri's HiddenHallows Several breweries were built atop these natural caves, which were altered to suit their purposes. Stone arches and brick ceilings prevented water seepage and uneven cave floors were paved with brick.

Park vegetation includes cottonwoods, willows, and other trees and shrubs as well as wetland plants such as cattails. The lake, which lies in a small artificial drainage basin, has no natural inlet or outlet. Water normally enters the lake only from rain, surface runoff, and groundwater seepage. Excessive aquatic plant life and algae have sometimes restricted the use of the lake, and its maintenance includes plant control and addition of fresh water from municipal wells.

Hydrothermal vents were one important source for the reduced iron that was later oxidized to form banded iron formations. There must be an ample source of reduced iron that can circulate freely into the deposition basin. Plausible sources of iron include hydrothermal vents along mid-ocean ridges, windblown dust, rivers, glacial ice, and seepage from continental margins. The importance of various sources of reduced iron has likely changed dramatically across geologic time.

The impervious zone may also be within the embankment in which case it is referred to as a core. In the instances where clay is utilized as the impervious material the dam is referred to as a composite dam. To prevent internal erosion of clay into the rock fill due to seepage forces, the core is separated using a filter. Filters are specifically graded soil designed to prevent the migration of fine grain soil particles.

Based on the idea that this fire-from-water image was inspired by flaming seepage natural gas, attempts have been made to connect the name "Apam Napat" to the word "naphtha", which passed into Greek—and thence English—from an Iranian language. However, there is no recorded evidence of a link between sacred fires of Iranian religion and petroleum or natural gas, and the origin of "naphtha" is likely Akkadian napṭu, "petroleum".

The excessive irrigation and intensification of agriculture over the years has caused environmental degradation and creation of new wastelands. There have been problems with water-logging caused by excessive irrigation, seepage from canals and poor drainage. These factors produced a rise in the water table (bringing soluble salts close to surface) , increased salinity and finally submergence of the land. These problems have been exacerbated by the cultivation of water intensive [cash crops].

Ice stalactites on gutter of house A common stalactite found seasonally or year round in many caves is the ice stalactite, commonly referred to as icicles, especially on the surface. Water seepage from the surface will penetrate into a cave and if temperatures are below freezing the water will form stalactites. Creation may also be done by the freezing of water vapor. Similar to lava stalactites, ice stalactites form very quickly within hours or days.

According to estimates in 1955, slightly more than half of the lake water leaves the lake through seepage and the rest through evaporation. It is possible that the lake overflowed over its southwestern rim, when the climate was wetter in the past and water depth reached . A channel is found there and this would explain the lack of salt deposits, and past shorelines indicate that the lake reached depths of . Water temperatures range from .

The site had been a area of rolling plains and hills used for cattle grazing (potreros). Hundreds of little asphalt springs dotted the area where cattle bones could be seen caught in the black seepage. Oil drilling in the area began in 1906. The town's population grew exponentially following the drilling of the Cerro Azul No. 4 well, at the time the world's largest pumping 260,000 barrels per day (BPD), in February 1916.

These works continued until December 2009 when water seepage caused a portion of the two-story building and colonnade to collapse. The restoration works were subsequently completed in March 2011. In 2014, the building was converted into a shopping and dining precinct, with the historic architecture having been preserved. The renovation and conversion works was carried out by the Urban Development Authority with the assistance of the 10th Engineering Regiment of the Sri Lankan Army.

Two recurring themes are often in her works – One is the mystery of interface, the edge or the space that separates one thing or place from another, defining both sides. The other concept is that of pentimento, a painting term about transparency, layering, and visual seepage. The resulting work is created through a process layered, aggregated, and deconstructed materials to form a whole, which are then erased, built upon, torn down, and reconstructed.

Some clinicians may also include milk blisters as a type of bleb. In addition, a blocked Montgomery gland may also be called a nipple bleb though its cause is different than a milk or serous-filled bleb on the nipple. In some cases the bleb may be associated with an adjacent blocked sebaceous cyst. It may be caused by a blocked pore that leads to seepage of milk or serous fluid under the epidermis.

The Blue Lake is drained by the west branch of the Sabine River, which is part of the Buller River system. It is fed by a short upper segment of the Sabine, which in turn is fed by underground seepage through the landslide debris impounding the much larger Lake Constance. Blue Lake is roughly boomerang shaped, running north then northwest, with each arm of the lake stretching some . Its waters are cold, ranging from .

A common stalagmite found seasonally or year round in many caves is the ice stalagmite, commonly referred to as icicles, especially in above-ground contexts. Water seepage from the surface will penetrate into a cave and if temperatures are below freezing temperature, the water will collect on the floor into stalagmites. Deposition may also occur directly from the freezing of water vapor. Similar to lava stalagmites, ice stalagmites form very quickly within hours or days.

It is found widely through all Australian states, but not the Northern Territory. It is also found in New Zealand, New Guinea and Norfolk Island. In Western Australia it is found in and around swamps and clay pans in the Mid West, Wheatbelt, Great Southern and Goldfields-Esperance regions where it grows in sandy-peaty- clay soils. It typically occurs in water or wet soil, seepage areas, freshwater lakes, and creek-beds.

Parts of this property, as well as adjoining lands, are designated as the Scotch Corners Provincially Significant Wetland. The property is one of several protected by the Mississippi Madawaska Land Trust. This seepage valley has a deciduous forest canopy, with an understory of ostrich fern, and supports several with calcium- demanding plants including Clinton’s fern and narrow-leaved spleenwort. This valley is a headwater for a stream that eventually feeds into Mississippi Lake.

The nymphs tunnel into the soft earth around alpine swamp or seepage in Schoenus tussock grassland. Even when forest cover is present the larvae prefer wetlands in forest clearings. They occupy a chamber half-filled with water for perhaps 5–6 years, emerging at night to seek prey near the burrow entrance. Tillyard observed that the larvae when dug out of their burrows are docile, not aggressive like those of U. carovei.

The drainage basin of the Ombla is estimated to cover an area of at least , and up to between the Adriatic Sea coast in the area of Dubrovnik and Popovo Polje. Other than the short surface course of the river, the drainage basin includes groundwater only. The exact boundaries of the drainage basin vary depending on prevailing hydrological conditions determining groundwater seepage and flow. The area comprises 176 settlements and 50,000 inhabitants.

Pichaikaranpallam Canal is a canal that runs in Erode, Tamil Nadu. It is one of the tributary to River Kaveri. The canal gets sourced by the rain water through rivulets and the seepage water from LBP Canal near Nasiyanur, which further flows into Ellapalayam Tank. The canal runs a length of through Ellapalayam, Villarasampatti, Periyasemur, BP Agraharam and passes under the Kalingarayan Canal with the help of an Aqueduct to reach River Kaveri.

On October 20, 2014, during an informal inspection, a sinkhole was discovered at the toe of the dam that allowed water to seep through. Consequently, a decision was made to start lowering the water level in the lake earlier than normal as a cautionary measure. On July 30, 2015, a media briefing was held discussing the results of a formal inspection of the dam. Internal erosion was found to be the cause of the seepage.

Because of the constant water seepage, it was not uncommon for the workers to work in knee- high or even waist-high water. By 1948, some 800 workers were working on the site. The tunnel was completed in March 1949, when the northern portal was opened and the first water flowed through the tunnel. Work then started by building cofferdams to block the natural channel of the river and allow dam construction to begin.

The Karankawa traveled to the mountains and basins region. They hunted and gathered food from rivers and by the mountains. In the region that the Karankawa inhabited, numerous small chunks of asphaltum have been found along the coast from oil seepage beneath the Gulf of Mexico. These chunks were used to bind arrowheads to their shafts; as a coating for pottery such as ollas, jars, and bowls; and as a way to waterproof woven baskets.

The Chamber was inaugurated on 21 November 1871. But the building proved wholly inadequate: the acoustics were terrible, it was very cold in winter and very hot in summer. As a result of extensive damage from water seepage, the palace was condemned in 1900. An attempt to build a new palace for the Chamber of Deputies on the Via Nazionale failed, and a provisional meeting hall was built on the Via della Missione.

TVA officials were also confirmed to have been aware of the toxicity of coal ash as early as 1981. In the 1980s, TVA engineers raised concerns about the stability of ash ponds. The utility repeatedly found leaks in levees and seepage in the soil at many of their ash ponds, including the ones at Kingston. However, TVA continued to make small repairs instead of switch to dry storage systems in an effort to reduce costs.

Nepenthes northiana is endemic to the Kuching Division of Sarawak, particularly the hills around the village of Bau. The species has an altitudinal distribution of 0 to 500 m above sea level and is restricted to limestone substrates. Nepenthes northiana growing in large clumps on the limestone cliffs of Bau Nepenthes northiana generally grows in exposed sites on near-vertical limestone cliffs with permanent water seepage. Less commonly it occurs in secondary vegetation on small hills.

Sunnambu Canal is a water stream canal that runs in the northern part of Erode city. It was once a celebrated natural channel which supplied water for irrigation of lands in the surrounding areas it runs through. Being one of the minor tributaries to River Kaveri, the canal gets sourced by rain through smaller rivulets and the seepage from LBP Canal. It starts near Chithode and ends its travel by inflowing into River Kaveri near RN Pudur.

As a result, the main causes of water loss are evaporation and seepage. The Lake Eyre Basin consists of seven drainage catchments, with the Georgina Diamantina, Cooper Creek and Neales Peake catchments located fully or partially in South Australia. Rainfall is one of the most influential climatic processes that acts upon the Lake Eyre Basin. The Lake Eyre Basin receives more rainfall during the summer season due to the high-pressure ridge of the Handley Cell.
|
|
Several of the major Lake Eyre Basin river systems are well-known. Because the Lake Eyre Basin is almost flat, rivers flow slowly and frequently split up into floodplains or multiple braided channels. Water is lost to evaporation, to seepage, and in the many ephemeral wetland systems, with the result that downstream flows are typically smaller than upstream flows. Only in exceptional years is there sufficient upstream rain to provide a flow into Lake Eyre itself.

This is a flush and spring fen, which has to be maintained as such, to ensure continued biodiversity. This is because the minerals in the groundwater seepage at this mire support, for example, rush, sedge, liverwort and moss. Therefore the underground aquifers should not be compromised by commercial water extraction, nor should they be contaminated by heavy use of agricultural fertilisers or by industrial pollution. A little fertiliser can be used, but downhill of the springs.

GCI maintains that the current protocols with regard to Lake Powell are environmentally damaging and wasteful. The group asserts that draining the reservoir would, among other things, save Lake Mead. According to GCI, Lake Powell currently loses up to of water through evaporation and seepage which would otherwise be contained in Lake Mead, which currently has more than enough storage to contain the extra water. That water use is equivalent to the entire consumption of Los Angeles.

The IBA comprises a small brackish lagoon and its associated vegetation, with an area of about , on the mid south-eastern coast of the main island, next to Forest Bay. It receives water from rainfall runoff as well as seawater seepage from the bay. It consists of two basins that are separated by a mudflat when the water level is low. The western and southern side has a substrate of limestone; that of the eastern is sand and marl.

The Taj Mahal is built on a parcel of land to the south of the walled city of Agra. Shah Jahan presented Maharajah Jai Singh with a large palace in the centre of Agra in exchange for the land. An area of roughly was excavated, filled with dirt to reduce seepage, and levelled at above riverbank. In the tomb area, wells were dug and filled with stone and rubble to form the footings of the tomb.

The lake consumes water to the extent that all the water in the lake must be replenished every year. Regarding water evaporation, lake documents state that according to the USDA Water Conservation Laboratory in Phoenix, the mean annual evaporation rate for Sahuarita is per year. This results in a mean water loss of per year. Regarding water loss due to seepage, initial estimates indicated an annual loss of of water, or 17% of total capacity per year.

Trees are densest in gorges, along the edge of streams and in areas where springs emerge. Growing at the edge of the groundwater forest are dense stands of yellow fever trees (Acacia xanthophloea) and the palm Phoenix reclinata. A fever acacia in Lake Manyara National Park Woodlands on the western shore of the lake dominated by Acacia and Commiphora species are also supported by groundwater. Trees are spaced irregularly; densest in zones of seepage and along drainage channels.

Stephen Chung () is a Taiwanese politician who served on the Legislative Yuan from 1999 to 2002 and again from 2004 to 2005. He earned a degree from Chinese Culture University before moving to the United States to study at Boston University. In October 1999, Chung, Chen Ching-pao, and Lin Chung-mo visited the Lungmen Nuclear Power Plant. The inspection, undertaken shortly after the 921 earthquake, found rusty reinforcing bars and potential for seawater seepage into the plant's foundation.

Boating continued on the lake until the 1930s, but by then its water had become polluted by asbestos and oil seepage from the neighbouring Anglo American Oil depot. During the Second World War the site was used as a tip for foundry waste. Esso bought the land in 1974, and levelled and partly seeded it, to improve the frontage to its own site. Trafford council bought the land from Esso in 1983, for £50,000 (£ as of ).

As sources of permanent fresh water they have high hydrological value. They feed on waters from various sources, such as seepage from the Ngozumpa glacier, a stream coming from the Renjo La pass from north-west and another stream originating from the Ngozumpa glacier in the east. These are glacier-fed freshwater wetlands and discharge water to the Dudh Kosi headway via the Taujon Lake and the Longabanga Lake. These lakes are deeper than previously assumed by the researchers.

A direct connection between the Gokyo Lake and the upper Thonak Cho and the Ngozumpa Cho has not been observed, but these lakes may be connected via underground seepage water. The Gokyo lake system is naturally vulnerable, as it is lying in an ecologically fragile and unstable zone. The outburst of Ngozumpa glacier is always a threat to the existence of the lakes. The Gokyo lake system of 19 lakes is spread over an area of lying between .

Metamorphosis occurs between December and February. P. pengilleyi prefers to breed in sphagnum bogs and wet heath in sub-alpine areas and dense patches of herbs in openings or seepages amongst fallen tussocks at lower elevation (bog pools at high altitudes above 1300 m and in shallow seepage pools in gullies at lower altitudes of 1000–1400 m). Other reproductive details are as for P. corroboree. Both species are restricted to mountain and sub-alpine woodlands, heathlands and grasslands.

Tubeworms and soft corals at a cold seep 3000 meters deep on the Florida Escarpment. Eelpouts, a galatheid crab, and an alvinocarid shrimp are feeding on chemosynthetic mytilid mussels. Another unusual feature found in the abyssal and hadal zones is the cold seep, sometimes called a cold vent. This is an area of the seabed where seepage of hydrogen sulfide, methane and other hydrocarbon-rich fluid occurs, often in the form of a deep-sea brine pool.

In 2008, the City received a proposal that escaping methane be captured for commercial use. in 2010, it was noticed that the leachate tanks were filling faster than expected. A study found that stormwater retention basins at the site had not been properly lined and were leaking into the leachate tanks. A $446.790 project extended the lining to eliminate most of the stormwater seepage significantly reducing the frequency at which the tanks needed to be drained.

The Martis Creek watershed is east of the Sierra Nevada crest and drains . It has four perennial tributaries, in order (heading downstream): West Fork Martis Creek, Middle Fork Martis Creek, East Fork Martis Creek, and Dry Lake Creek. The tributaries join Martis Creek above Martis Creek Reservoir, except for Dry Lake Creek. The United States Army Corps of Engineers (USACE) has identified significant problems with Martis Dam, including significant seepage and seismic dangers which they are currently studying.

Basement walls may need to have the surrounding earth backfilled around them to return the soil to grade. A water stop, some gravel and a french drain may need to be used to prevent water from entering the basement at the bottom of the wall. Walls below grade may need to be sealed with an impervious coating (such as tar) to prevent water seepage. A polyethylene of about 6 mil (visqueen) serves as a water barrier underneath the basement.

Air and water temperatures are relatively stable with an annual average of 28.25 ± 1.23 and 26.33 ± 0.96 °C, respectively (range = 25.0–32.7_C for air; 22.9–29.3 °C for water). The cave is subject to frequent flooding during the monsoon season, which generally begins in the middle of June and continues until the middle of October. The site is closed to tourists during this period. Various water pools fed by seepage throughout the year also exist in this cave .

A study conducted by Guthrie et al. (2012) concluded that groundwater played a key role in the collapse. Prior to failure the flanks of Meager were subject to high pore water pressures indicated by extensive surface seepage observed throughout the failure surface and along lateral shears following the 2010 event. The largest visible bedrock spring occurred along the west lateral scarp and was the location of at least two previous landslides, occurring in 1998 and 2009.

In 1985, it was found that water seepage into the foundations of the Spring Creek Dam could possibly cause its collapse. Shortly after the discovery, a controversy over the irregular spills of mine toxins from the dam began in the 1990s. Two years later, in March 1992, an uncontrolled, unexpected spill of acidic water rushed from the dam down Spring Creek. This spill heavily contaminated the Keswick Reservoir and threatened the water supply of Redding, California.

While the area received enough rainfall for agricultural production, there were few freshwater sources for domestic use. Water had to travel 749 m (about half of a mile) to reach the city center. The Inca exhibited a large degree of technological prowess in their careful gradation of the aqueducts. By cutting the canals out of one stone, lining canals with rock, and filling joints with clay, the Inca were able to reduce water loss due to seepage.

Even the murals on the walls had been damaged because of water seepage and these were also restored by RCL. Despite what is mentioned here regarding the restoration of these paintings, recent visits to the Jaganmohan Palace suggest gross neglect. These priceless paintings are ill maintained and incompetently restored. For example, in the painting of Ravana slaying, Jatayu by Raja Ravi Varma the colors used to restore the painting are different from the ones used in the original painting.

Banana, bamboo and secondary scrub grow on both sides of foot tracks in the forests. The forest also has an abundance of cascading streams, seepage streams from limestone formations, waterfalls, glides, and pools. The stiff limestone vertical rock face is seen above on the northeast face of Mount Muong Cha, while its southwest slope exhibits a much gentler gradient, and is converted into agricultural fields. Above , there is a montane mixed semideciduous and evergreen cloud forest.

An organ constructed by New Yorker Henry Erben was assembled at Trinity in 1857. The organ was disassembled in 1902 and rebuilt with a section of eight foot diapason pipes. A three manual, 22-rank Austin Organ, model Opus 504, was placed in the church during 1914 in memory of Junius T. Smith by his widow, Laura. It was used for over 50 years until its deterioration from wood destroying organisms and water seepage was beyond repair.

As a coral-limestone island, Barbados is highly permeable to seepage of surface water into the earth. The government has placed great emphasis on protecting the catchment areas that lead directly into the huge network of underground aquifers and streams. On occasion illegal squatters have breached these areas, and the government has removed squatters to preserve the cleanliness of the underground springs which provide the island's drinking water."Squatters get thumbs down from MP Forde" .

The investigation also recorded active oil seepage from the ship's fuel tanks. Another survey of Houston occurred in October 2015, with United States Navy and Indonesian Navy divers embarked aboard for a nine-day survey of Houston and Perth (which had also been subject to unauthorized salvaging). Divers documented the condition of the two shipwrecks, with this data presented to a conference in Jakarta on preserving and preventing the illegal salvage of wartime shipwrecks in the Java Sea.

Breitenbush Lake is a water body on a high plateau north of Mount Jefferson in the Cascade Range in the U.S. state of Oregon. The lake, fed by seepage and small creeks, is part of the North Fork Breitenbush River watershed. It is in Marion County near its border with Jefferson County and lies within the Mount Hood National Forest and the Warm Springs Indian Reservation at an elevation of about . Forest Road 4220 runs by the lake.

The lake is located inside the summit crater of Licancabur and was discovered by climbers in 1953, when it was long. While the lake may have overflowed in the past, presently it is only drained by seepage and evaporation. It covered a surface area of in 2002; lake levels vary otherwise. The lake has clear waters and is slightly saline; temperatures ranging between and as recorded at the lake bottom in 2006 suggest it is subject to geothermal heating.

The double-walled rooms were fully protected against external threat and were well ventilated by round ventilation holes in the roof. A thin brick wall in one corner of the godown helped soldiers escape in case of emergency. The sloping ceiling of the godown prevented seepage of rainwater. The fort has 48 rooms that were once used as cells to lodge war prisoners and slaves, a spacious kitchen, a horse stable and a meeting hall for the army commanders.

View of the Colorado immediately downstream of Glen Canyon Dam (right). The green, clear water is caused by the dam trapping sediment, which would naturally cause the river to have a reddish-brown color. Because of its tremendous ecological effect on the Colorado River, the Glen Canyon Dam has been subject to decades of criticism from the environmental movement. Being located in a high desert climate amid porous geology, Lake Powell causes huge evaporation and seepage losses.

Their formation and growth patterns have been hotly debated and multiple hypotheses have been proposed. One hypothesis connects their formation to the seepage of hydrocarbons, either along faults or from former gas-hydrate layers, as a response to glacial-interglacial changes in current patterns and sea levels. Another hypothesis relates their distribution to nutrient fluxes driven by specific oceanic conditions, notably the interaction of internal waves, formed at the boundary between different water masses, with the continental slope.

Breeding takes place in the summer. The female lays a clutch of about fifteen eggs in a damp crevice, under a rock or rotten log or among wet moss or leaf litter. She broods the eggs for one or two months after which the newly hatched larvae make their way to a stream, a seepage or rocks over which water is flowing. They feed on small aquatic invertebrates and undergo metamorphosis the following spring or summer.

Her outside interests included traveling throughout the world. Through dedicated work and interest, Mary became a distinguished carbonate stratigrapher and was considered to be an expert on several of the Permian basin rock units. She was also known to have taught hundreds of earth scientists who worked in the petroleum industry. Rhodes and co-worker John Emery Adams shared an interest in Permian basin and were coauthors of two papers, Starved Pennsylvanian Midland Basin and Dolomitization by Seepage Refluxion.

Since 1985, sewage effluent from Doha has been dumped in a depression (rawda) in Abu Nakhla. Combined with gradual and continuous rainfall during the rainy season, the depression has morphed into a 2 to 3 km pond. Locals have long complained about negative environmental and health effects resulting from the pond, including increased pest populations, foul odors and seepage into aquifers. There is also a strong perception that the sewage water is untreated, and could pose a health hazard.

By the 1980s the track was only being used for lap dashes with single cars on track at one time and was used until the mid-1990s for this. The circuit still exists and can be walked around however it has deteriorated quite badly with grass growing through the track surface on what was Lockheed Straight and Dunlop Corner, and water seepage has caused part of the track to collapse between Craven A corner and Castrol corner.

The best known of these communities was named Bush Hill by the investigators who first described it (MacDonald et al., 1989b). It is a surprisingly large and dense community of chemosynthetic tube worms and mussels at a site of natural petroleum and gas seepage over a salt diapir in Green Canyon Block 185. The seep site is a small knoll that rises about 40 m (131 ft) above the surrounding seafloor in about 580-m (1,903-ft) water depth.

Some lakes do not have a natural outflow and lose water solely by evaporation or underground seepage or both. They are termed endorheic lakes. Many lakes are artificial and are constructed for hydro-electric power generation, aesthetic purposes, recreational purposes, industrial use, agricultural use or domestic water supply. Evidence of extraterrestrial lakes exists; "definitive evidence of lakes filled with methane" was announced by NASA as returned by the Cassini Probe observing the moon Titan, which orbited the planet Saturn.

After a rebuild was completed in 1994, the tunnel reopened in 1995. The tunnel was again closed for repairs between January and June 2017. Workers sealed cracks in the vintage concrete to reduce seepage, repaved the road, replaced water and sewer lines, and installed energy-efficient LED lighting. Prior to the 2017 rehabilitation, the tunnel was the second-largest consumer of power in the entire Golden Gate National Recreation Area (after district headquarters in San Francisco).

The maximum coverage of the tunnel was 35 metres. Chimneys were built at this height to remove the smoke caused by steam locomotives. The masonry was continuously damaged by seepage and exhaust gases from the steam locomotives, so that the tunnel was in great need of restoration at the beginning of the 1930s. The tunnel was not exactly straight when built, so over time work was carried out to straighten it, which further reduced its stability.

Iron ore was discovered in what is now the Iron Mountain area in 1878. Development was rapid: Iron Mountain was platted in 1879 and the Chapin Mine Company was formed the same year. The Chapin Mine proved to be the most productive in the Menominee Range, but part of the ore body was underneath a cedar swamp and water seepage proved to be an ongoing problem. Ground pumps were used at first, but as the shaft depth increased, so did the problems.

The Dos Palmas Spring is now part of the Dos Palmas Preserve a 14,000-acre preserve created to protect important biological resources. The oasis with its hundreds of desert fan palms and pools fed by artesian springs and seepage from the nearby Coachella Canal form a wetland that offers shelter from the hot, dry Colorado Desert to a variety of both threatened or endangered and more common animal species. These include the endangered Yuma Rail, the Desert Pupfish and the Orocopia Sage.

The lake originated when debris flows in steep canyon walls dammed the Callazas River. The waters of the lake are currently diverted to a hydroelectric plant, which has lowered the lake level from ~800.000 m3 in 1967 to a monthly average of 140.000 m3 in 2000. Main inflow sources of the lake are the Callazas River and the Jaruma creek. The main outflow is due to seepage through the debris dam to the Curibaya River (although hydroelectric use could count also).

Sandbag structures do not prevent water seepage and therefore should be built with the central purpose of diverting flood water around or away from buildings. Properly filled sandbags for flood control are filled one-half to two-thirds full with clean washed sand. In an emergency, if clean sand is in limited supply, gravel or dirt can also be used with less effective end results. When filled sandbags are stacked or laid in place, the contents need to settle flat to the ground.

1146-1161 Methane can be trapped and stored under the seabed as a gas hydrate, and under different conditions, can either be controlled by microbial consumption, or can escape into the surrounding seawater, and ultimately the atmosphere. Our understanding of the biological controls of methane seepage and feedback mechanisms for global warming is limited. The distribution and structure of cold seep communities can act as an indicator for changes in methane fluxes in the deep sea, e.g. by seafloor warming.

In November 1938, the two segments of the tunnel met under the mountain, no more than a few inches off. With the excavation completed, the tunnel was then grouted with concrete. This operation filled in cracks and crevices and reduced the tunnel to its finished size of 16 feet (4.9 m) tall and 16 feet (4.9 m) wide. About 24,100 tons of cement were used in the attempts to seal off the seepage, averaging about 20 sacks per foot of tunnel.

The J. Harlan Glenn Engineers that provided this estimate indicated that this equates to an "extremely low seepage rate". On average, 65 gpm (gallons of water per minute) must be pumped into the lake to maintain its current level. A nearby well site that draws on the shared Upper Santa Cruz Valley aquifer is used to refill the lake. In 2006, of water was used for the entire Sahuarita lake park, which includes water for the of grass and restroom facilities.

Red Rock Pass, Idaho. About 14,500 years ago, pluvial Lake Bonneville in northern Utah reached its highest water level since its formation. The lake occupied the present-day basin of the Great Salt Lake, but was far larger, covering about . As it rose the lake level caused seepage at, then breached, the ancient level of Red Rock Pass, a mountain pass at the headwaters of the Portneuf River, a tributary of the Snake River above present-day American Falls Reservoir.

Terenah are constructed as a series of well-like vertical shafts, connected by gently sloping tunnels. Terenah tap into subterranean water in a manner that efficiently delivers large quantities of water to the surface without need for pumping. The water drains relying on gravity, with the destination lower than the source, which is typically an upland aquifer. Terenah allow water to be transported over long distances in hot dry climates without losing a large proportion of the water to seepage and evaporation.

There were several episodes of continental collision, compression and subduction which resulted in mountain building during this time. Orogenic events are characterized by extensive metaphorism, granitic extrusions and unconformities. The Algoman orogeny added landmass along a border from South Dakota to the Lake Huron region; this boundary is the Great Lakes tectonic zone (GLTZ). Northeast Minnesota has 2700-million-year-ago exposed rocks formed during volcanic activity that was in the form of seepage of lava from rifts in the sea floor.

A lower watertable (unsaturated beach face) facilitates deposition by reducing flow velocities during backwash and prolonging laminar flow. With the beach in a saturated state, backwash velocity is accelerated by the addition of groundwater seepage out of the beach within the effluent zone. However, no case studies provide indisputable evidence of positive results, although in some cases overall positive performance was reported. Long-term monitoring was not undertaken at a frequency high enough to discriminate the response to high energy erosive events.

ASI has constructed break-water wall all around the sea shore to save the temple from further damage. The temple structures, affected by rough Sea and winds with salt content are being conserved by the Archaeological Survey of India by building protective groynes, treatment with wall paper pulp, and by planting casuarina trees along the affected coast line. The pulp treatment absorbs the saline water. In addition, chemical treatment is also given the monument to prevent water seepage into the rock.

NRC officials were at the plant at the time and NRC statements said the plant remains safe. NRC Chairman Gregory Jaczko confirmed the plant's safety when he visited the plant on June 27. On June 30 one of the pumps used to remove seepage caught fire when a worker was refilling it with gasoline. The worker put the fire out with a fire extinguisher but was burned on his arms and face and he was airlifted via helicopter to Lincoln, Nebraska.

In 2003, the reservoir was desilted by Indian National Trust for Art and Cultural Heritage, an NGO based in Delhi and Haryana. A well for the supply of water for drinking and other purposes exists on the top of hill which is recharged by seepage and percolation of water from adjoining reservoirs which are charged by the rainwater on the hill. The Government of Haryana now provides drinking water at the hill through mechanical uplifting from the base of the hill.

Problems of water seepage, internal condensation, bad acoustics, and poor indoor air quality can occur if an earth shelter has not been properly designed and ventilated. Very high humidity levels can allow mold or mildew growth, associated with a musty smell and potentially with health problems. The below-ground orientation of many earth-sheltered homes can allow accumulation of radon gas (which is known to increase the risk of lung cancer) or other undesirable materials (e.g. off gassing from construction materials).

The southeast portion has deep valleys from which flows the Chontalcoatlan River toward the Balsas River. The volcano's watersheds feeds a number of freshwater springs and streams, but the capacity of this watershed is being compromised the erosion and deforestation. The erosion has formed ravines with steep sides and 15 cm deep, which does not allow for the seepage of water into the subsoil. This is one of the reasons why a number of springs in the area have dried up.

The Marys Rock Tunnel was partially lined with concrete in 1958 to prevent icicles in the winter and water seepage in the summer. In 1983, the Federal Highway Administration began work to replace several of the original stone walls on the drive with concrete walls that used the original stone as a veneer. The road was added to the National Register of Historic Places on April 28, 1997. On September 22, 2005, Skyline Drive was designated a National Scenic Byway.

As with the Moffat Tunnel, while the Eisenhower Tunnel was primarily intended as a transportation tunnel, it also serves as a water tunnel for water diversion from the western side of the Continental Divide to the eastern side. Water from the Straight Creek watershed (a tributary of the Blue River), along with all seepage entering the tunnel is discharged into Clear Creek for delivery to the Coors Brewing Company. Typically, the tunnel delivers over 300 acre-feet (370,000 m3) of water per year.

In 1967 a leak was found at the Wolf Creek Dam. Repairs were made in the late 1970s at a cost of over $96 million. On January 22, 2007, the United States Army Corps of Engineers began lowering the water level in Lake Cumberland, fearing a possible breach in Wolf Creek Dam. Water seepage had eroded the limestone under the dam, creating the potential for a breach and subsequent flood that would cause damages into the billions of dollars in cities downstream.

Qanats are constructed as a series of well-like vertical shafts, connected by gently sloping tunnels. Qanats tap into subterranean water in a manner that efficiently delivers large quantities of water to the surface without need for pumping. The water drains relying on gravity, with the destination lower than the source, which is typically an upland aquifer. Qanats allow water to be transported over long distances in hot dry climates without losing a large proportion of the water to seepage and evaporation.

It has no outlet, with water leaving only by evaporation, or sub-surface seepage. The lake has about 10% of the area of the Great Salt Lake, but it has about 25% more volume. The salinity is approximately 1/6 that of sea water. Although clear Lake Tahoe forms the headwaters that drain to Pyramid Lake, the Truckee River delivers more turbid waters to Pyramid Lake after traversing the steep Sierra terrain and collecting moderately high silt-loaded surface runoff.

Note the small entrance to the trap underneath the swollen 'balloon', and the colourless patches that confuse prey trapped inside The cobra plant is not just restricted to nutrient-poor acidic bogs and seepage slopes, but many colonies actually thrive in ultramafic soils, which are in fact basic soils, within its range. In common with most carnivorous plants, the cobra lily is adapted to supplementing its nitrogen requirements through carnivory, which helps to compensate for the lack of available nitrogen in such habitats.

The seabed morphology in the central depression of the gulf is characterised by the presence of elongated mounds and ridges arranged parallel to the axis of the basin. This morphology, widespread within the gulf in water depths exceeding 50 m, covers an area of tens of thousands of square kilometres. It reflects an interaction between sediment dewatering and the erosional activity of the present-day bottom currents. The sediment dewatering and fluid seepage result in the formation of numerous small pits and pockmarks.

From Poondi, water is distributed through a system of link-canals to other storage reservoirs located at Red Hills, Sholavaram and Chembarambakkam. The project was approved in 1977 after an agreement was reached between Tamil Nadu and the riparian states of Krishna river: Andhra Pradesh, Maharashtra and Karnataka. According to the agreement, each of the three riparian states were to contribute of water annually, for a total supply of . This number was revised down to in 1983 after accounting seepage and evaporation loses.

Finding a moist place to lay the eggs is only necessary so the eggs do not dry out, as once the eggs hatch the hatchlings will not live in water. D. organi can be found mostly on the forest floor under moss, leaf litter, fallen logs, or small stones. It has been observed that they seem to prefer smaller covers of woody debris rather larger covers, such as big rocks. D. organi will overwinter in clusters underground in seepage areas, often communally.

The arrival of the 808th Engineer Aviation Battalion permitted extensive rehabilitation work on Jackson. The runway had been sealed with an excess of bitumen, which became soft in the heat, and parked aircraft tended to sink into it. When the bitumen was removed to be re- laid, hydroscopic clay under parts of the runway became supersaturated through seepage, and springs developed. The engineers were forced to install underground drains, and put down a new base of crushed rock, which was sealed with bitumen.

Centrolepis polygyna, commonly known as wiry centrolepis, is a species of plant in the Restionaceae family and is found in Western Australia. The reddish annual herb has a tufted habit and typically grows to a height of approximately . It blooms between July and December. It is found in winter wet depressions and seepage areas in the Wheatbelt, Mid West, Peel, South West, Great Southern and Goldfields-Esperance regions of Western Australia where it grows in sandy-clay soils over laterite.

The presence of oil in Indian Territory had been observed for many years, usually as natural seepage from the ground. Oklahoma Historian Muriel H. Wright described an incident in 1859, in which Lewis Ross, the brother of Cherokee Chief John Ross, attempted to drill a deep water well for the salt works he owned in the Cherokee Nation. Instead, the well hit an oil formation. She reported that production was estimated at ten barrels a day for nearly a year.

Water began to fill the reservoir on March 12, 1926. It rose steadily and rather uneventfully, although several temperature and contraction cracks did appear in the dam and a minor amount of seepage began to flow from under the abutments. In accord with the protocol for design, which had been established by the engineering department during construction of the Mulholland dam, no contraction joints were incorporated. The most notable incidents were two vertical cracks that ran down through the dam from the top.
|
|
During this time though, several new cracks appeared in the wing dike and new areas of seepage began from under both abutments. Near the end of February, a notable leak began at the base of the wing dike approximately west of the main dam. It was discharging about 0.60 cubic feet per second (4.5 U.S. gallons, or 17 liters, per second) and was inspected by Mulholland who judged it to be another contraction or temperature crack and left it open to drain.

In the early 1900s, Pancoast Creek was clear of culm from its source downstream to its mouth unlike Price Creek, into which it flows. However, Pancoast Creek was discolored by streams of surface water and sewage. The borough of Dickson City once applied for a permit to discharge stormwater into the creek. A mid-20th-century report estimated that the rate of surface water seepage into mine workings at Pancoast Creek was 6.24 gallons per minute per inch of rain.

Both individuals and communities appear to be very long lived. These methane-dependent mussels have strict chemical requirements that tie them to areas of the most active seepage in the Gulf of Mexico. As a result of their rapid growth rates, mussel recolonization of a disturbed seep site could occur relatively rapidly. There is some evidence that mussels also have some requirement of a hard substrate and could increase in numbers if suitable substrate is increased on the seafloor (Fisher, 1995).

The Lowveld displays a younger erosional surface cut, and the Karro rocks, specifically the Stormberg basalts and Ecca shales, display older surfaces. The geomorphic setting is diverse, as the Lebombo rhyolites are poorly laminated, slightly banded with phenocrysts of feldspar and occasional quartz. The differences come from the different rates at which cooling and crystallization occurred in the different textural zones. There were slower rates of change during the later Pleistocene and a total absence of seepage water through the walls.

Bogs get water from the atmosphere, while fens get their water from groundwater seepage. Cataract bogs inhabit a narrow, linear zone next to the stream, and are partly shaded by trees and shrubs in the adjacent plant communities. Cataract bogs are found only in the Southern Appalachian Mountains of the United States, at elevations of between . They are restricted to the Blue Ridge Escarpment region of South Carolina and a small area of North Carolina, a region with exceptionally high rainfall.

The USACE did not believe the dam was at immediate risk of failing but assessed increased danger to downstream communities until the problem was resolved. The USACE began to lower and restrict the elevation of the dam's reservoir. In addition, by November 2009, the USACE constructed an interim seepage barrier along with improving the drainage of the right abutment. These actions were estimated to reduce the chance of flooding from a 1 in 3 to a 1 in 25 chance during 2010.

L. catherinae can be found from the Middelberg in the Cedarberg mountains in the north, to the Kouebokkeveld Mountains and Ceres mountains in the south. Isolated populations occur at Bokkerivier and on the Piketberg Mountain. The species has a strong preference for moist situations, mostly growing on level sandy flats along the banks of year-round streams or in seepage areas with a gravelly underground of weathered table mountain sandstone. The locations where it grows have an elevation of 600–1200 m (2,000–4,000 ft).

The site preserves a seepage wetland that supports a large collection of rare plants, including camass, bog-buttons, fringed orchids, and purple pitcher plants. This diverse community of plants has previously been maintained by frequent fires that prevented the long-term domination of woody plants. Since 2000, the DCR has managed the site with prescribed fire to expand and maintain the habitat for rare, fire-dependent plants. In 2014, the DCR began restoration work on the longleaf pines at the Cherry Orchard Bog preserve.

The USCG said the oil was too dispersed to recover and posed no threat to the coastline. In March 2012, "persistent oil seep" near the Macondo well was again reported. More sightings in October 2012 prompted another investigation into the source of the continued oil seepage. The USCG again found the oil was a chemical match for Macondo, and sent a Notice of Federal Interest to BP and Transocean which warned they may be held financially responsible for clean-up related to the new oil.

The county council maintained the principal contractor and appointed civil engineers, URS to complete the works. The water level in the reservoir was lowered by from February to April in 2010, in order for the works to be carried out on the eastern dam. To reduce the risk of internal erosion filters were installed at the downstream toe of the embankment to control and monitor seepage through the dam. To meet regulations the reservoir has to be able to withstand a 1 in 10,000-year storm event.

Hickory Hollow Natural Area Preserve is a Natural Area Preserve located in Lancaster County, Virginia. The preserve's mixed pine-hardwood forests, ravines, and swampland form a habitat for various songbirds, wild turkeys, and a rare species of plant. The swamp is an example of a globally rare natural community known as a "coastal plain basic seepage swamp", and supports a high level of biological diversity. Hickory Hollow Natural Area Preserve is owned by the Northern Neck Audubon Society, who purchased the land from Lancaster County in 1999.

The recharge zone of the spring, the surrounding hills are being built upon at an unprecedented rate. Septic tanks and soak pits are sending the waste-water generated into the ground. The surface is being crusted up with roads and buildings preventing the seepage of water into the ground. It is likely that the sacred ‘Jhira’ will first be contaminated by the bad water and if steps are not taken quickly, may also run dry due to lack of recharge of waters in the hills.

The River still carries elevated levels of lead, zinc and silver in its water, mostly due to seepage from abandoned mine tailings and discharges from mine adits. At the Frongoch mine near Pont-rhyd- y-groes, Natural Resources Wales has introduced a new technique for reducing the pollution. Water is drawn away from the mine in a leat to a wetland area, where biological processes involving the vegetation immobilise much of the pollutants. A similar approach is being used at Cwm Rheidol mine, near Aberystwyth.

The site of the Ecology Center was once a general dump owned by New York State, and was acquired by the Town of Brookhaven in 1937 for use as a town dump. Prior to this, the right of way for the Suffolk Traction Company trolley line also ran through this location. In 1968, the State Environmental Facilities Corporation converted the site into a sanitary landfill with seepage lagoons, and closed the facility completely by 1974. By 1971, the park was already under development, and opened in 1979.

The geologic Toluca Lake is a body of water located near the district’s southeastern boundaries. The historic natural lake was fed by springs of upwelling groundwater from the Los Angeles River and San Fernando Valley subterranean aquifers. Late 19th and 20th century L. A. DWP well extraction and 1930s concrete river channelization lowered the water table, and currently community wells at the lake’s edges maintain the water level. The bottom of the lake is surfaced with four inches (102 mm) of asphalt concrete to prevent seepage.

The dam was built to serve the purpose of flood control, irrigation and municipal water use. With heavy suburban sprawl downstream encroaching since the 1960s, agriculture along lower Santiago Creek has practically ceased. It is currently owned by the Irvine Ranch Water District and the Serrano Water District (the former Serrano Irrigation District). Today the dam marks the usual ending point of surface flow in Santiago Creek, as all the discharge is retained in the reservoir and downstream flow is limited to seepage and stormwater.

The IBA comprises five small ponds and their associated vegetation, with a total area of about 9 ha, on the Cuisinart Golf Course, near the south-western end of the main island, next to Rendezvous and Merrywing Bays. Two of the ponds are artificial, and are used as freshwater reservoirs for irrigation; the other three are natural and brackish, receiving both freshwater runoff from rainfall and seawater seepage from the bays. The site is vegetated with a mix of native and exotic ornamental plants.

Concerning groundwater quality, the prevalence of carbonate sedimentary rocks in the mountains in the north leads to pH values from 6.5 to 8.0 and a generally low mineral content. The Bakhtiari aquifer which lies in the northwestern mountain foothills has a thickness of up to 6000 m (18) and its water is generally of good quality. The exceptions are waters from shallow wells that are located near cities or villages. These waters are often contaminated, mainly due to the free seepage of sewage water.

By 1935 the seepage had become a concern around the San Jacinto Valley as springs, creeks and streams began to run dry. On October 21, 1935 the Riverside County Board of Supervisors passed a resolution calling on the MWD to prevent water from entering the tunnel or from flowing away from the place it was encountered. The MWD responded by stating that water entering the tunnel during digging is nearly unavoidable, and that lining of the tunnels near the end of construction should prevent further inflow.

The lagoon, a marginal-marine salina or marine lake, is an elongate depression about in area, with most of it lying a few metres below sea level. It is separated from the Indian Ocean by a beach barrier ridge and barrier dune system. Similar to Lake MacLeod, to the north of Carnarvon, Hutt Lagoon is fed by marine waters through the barrier ridge and by meteoric waters through springs. Due to the salina’s sub-sealevel position, seepage of seawater into the salina is continuous year round.

The flames also set fire to polyurethane foam that is used to keep walls in the mine dry. The burning plastic combined with polyurethane and churned toxic fumes that filled the shafts, choking miners to death. A welder's spark ignited plastic foam lining the walls of a tunnel, starting the fire which resulted in one of the worst disasters in mining history. The foam is used to stop water seepage, but contains a sealant called Rigiseal which gives off poisonous fumes when it burns.

Deliveries are monitored throughout the system as water enters and exits metered channels. Water that is transferred any distance suffers what are termed 'conveyance losses' which means that the amount of water released at the start is not the same amount that ultimately arrives. The difference between what is sent versus what is received are conveyance losses and can be the result of evaporation or seepage (soaking into the land). In some cases water travels over 300 miles to reach its final refuge destination.

According to a joint study by MWSS and JICA in 1991, most groundwater samples from Metro Manila's coastal areas were salinized. However, compared to the early 1980s, the saline intrusion was found to have improved conditions because of the conversion of water source from groundwater to surface water upon the completion of the Manila Water Supply Project II in 1987. Aside from excessive withdrawal of groundwater, seepage of brackish water along the Pasig River is another cause of saltwater intrusion because of seawater movement during tides.

The foundation and church developed a restoration plan over many years, beginning in 2000. In April 2009, Unity Temple, due to water seepage, was added to the National Trust for Historic Preservation's 11 most endangered historic places Chicago restoration architect Gunny Harboe was in charge of the restoration with CTLGroup providing the engineering and materials technology expertise. In April 2015, a $25 million interior and exterior restoration began. The restoration focused on structural improvements such as replacing the majority of the building's 16 separate flat roofs.

A dustcap is a small cover used on the valve stem of a bicycle or car tire to prevent dust or other small particles from entering the valve and damaging it. The dustcap also forms a pressure seal, helping to prevent deflation of the tire due to slight gas seepage past the tire valve. Dustcaps are usually made from plastic but may occasionally be made of metal. The dustcap is internally threaded and is secured by screwing it onto the end of the stem.

Krosno is located in an oil bearing region. Surface seepage of oil was locally used (unrefined) in lamps as early as the 16th century. In the 19th century Ignacy Łukasiewicz a local pharmacist began exploiting the deposits from hand-dug wells, years before the drilling at Titusville, Pennsylvania which is usually said to be the beginning of modern petroleum development. One of the things that Krosno is well known for is the quality glassware and crystal that is produced in the town, and distributed throughout the world.

Although adult trees can store water and are drought resistant, seedlings need a good supply of water to survive. This stops the species from growing in sand dunes unless there are wet depressions present, and from hillsides unless there is a seepage area. The fertility of the soil is another factor—settlers in Canterbury used the presence of the species to situate their homesteads and gardens. The fallen leaves of the tree also help to raise the fertility of the soil when they break down.

The Fruitland Formation contains beds of bituminous coal that are mined in places along the outcrop. Since the 1980s, the coal beds of the Fruitland Formation have yielded large quantities of coalbed methane. The productive area for coalbed methane straddles the Colorado-New Mexico state line, and is one of the most productive areas for coalbed methane in the United States. The methane released from the Fruitland Formation, through oil and gas production and a bit of natural seepage, contributes to the Four Corners Methane Hot Spot.

The nutrient contribution to False Bay surface waters by upwelling appears to be greater than that of terrestrial sources by runoff and groundwater seepage, but pollutants from terrestrial sources can be persistent and can have adverse effects on coastal ecosystems and recreational activities. Mixing with offshore water has a significant effect on surf zone and inshore water quality, but the effects of microbial processes on inshore water quality and the relative contribution of anthropogenic sources of nutrients remains unknown, but likely to be increasing.

There is another instructive structure located at the Kharga oasis. A well that apparently dried up was improved by driving a side shaft through the easily penetrated sandstone (presumably in the direction of greatest water seepage) into the hill of Ayn-Manâwîr to allow collection of additional water. After this side shaft had been extended, another vertical shaft was driven to intersect the side shaft. Side chambers were built, and holes bored into the rock—presumably at points where water seeped from the rocks—are evident.

Covered by a disc made of greased felt, the projectile was inserted in the barrel after it was tilted up by a lever, followed by the case, and (like the concurrent muzzleloaders, such as the Springfield) were ignited by percussion cap, which was placed on the bolt face. The brass cases had a paper patch in the base, to prevent powder seepage and still allow the cap to fire the round. The weapon was caliber with a barrel. The rifle was strongly made, but unpopular with troops.

Permeable paving surfaces keep the pollutants in place in the soil or other material underlying the roadway, and allow water seepage to groundwater recharge while preventing the stream erosion problems. They capture the heavy metals that fall on them, preventing them from washing downstream and accumulating inadvertently in the environment. In the void spaces, naturally occurring micro-organisms digest car oils, leaving little but carbon dioxide and water. Rainwater infiltration is usually less than that of an impervious pavement with a separate stormwater management facility somewhere downstream. .

The Thai governmental agency charged with responsibility for groundwater is the Department of Groundwater Resources, part of the Ministry of Natural Resources and Environment. Groundwater is mainly recharged by rainfall and seepage streams. Aquifers yield a large amount of water throughout Thailand, with the exception of the eastern region. The largest source of groundwater is found in the lower central region, particularly in the Bangkok Metropolitan Region (BMR) and surrounding provinces, and is being used to meet the growing water demand, growing at 10% annually.

Adults of most resemble those of Epimartyria pardella in possessing dark fuscous forewings marked by pale golden spots. A total of two yellowish spots occur, with only a single large costal spot present beyond the middle of the forewing. Specimens were captured by sweeping low lying vegetation or during diurnal flight along a shaded seepage in a Douglas fir–western red cedar forest where leafy liverworts grew. Adults were also observed perching on lower parts of plants such as Rubus spectabilis close to the liverwort habitat.

Also in 1994 (according to Pellegrini and Bianchini already in 1991 ) a cold local heating network was built in the Swiss village Oberwald, which is operated with seepage water from the Furka base tunnel. As of January 2018, a total of 40 turbines were in operation in Europe, 15 each in Germany and Switzerland. Most of the projects were pilot plants with a heat output of several 100 kWth up to the single-digit MW range, the largest plant had an output of approx. 10 MWth.

Once drained, workers excavated the alluvial deposits between the cofferdams, creating a long pit that was deep at the center. This pit was then filled with concrete in the summer of 1962. To prevent seepage in the dam's foundation, a grout curtain was injected in the bedrock and a drainage network with of tunnels was constructed just downstream of the dam to collect water that might seep through. After the extensive preparatory works were complete, the first concrete for the dam was poured on October 3, 1962.

There are also rare habitats, such as hillside seepage bogs and calcareous prairies. The forest also contains and provides a buffer for the Kisatchie Hills Wilderness, a nationally designated wilderness area that contributes to protecting biodiversity of the coastal plain region of the United States. The forest was designated in 1930 during the administration of U.S. President Herbert Hoover. Kisatchie National Forest plays an important role in protecting representative examples of the landscape of northern Louisiana, particularly those that fall within the South Central Plains Ecoregion.

During the Keian era (1651-1652), the output of the mine had dropped to only half of what it was at its peak, and operations were increasingly hampered by groundwater seepage. From 1671 to 1675, large- scale drainage projects were undertaken, but without success, and the mine was thereafter abandoned in either 1689 or 1703. The site is about a 20-minute walk from the "Ginzan Onsen" bus stop on the Osarizawa Municipal Bus from Oshida Station on the JR East Ou Main Line.

He wanted to see if blood would continue to flow through the head if three of the four arteries supplying blood to the head were tied. Lower also investigated to see how cerebrospinal fluid was formed and how it circulated. These experiments led to a study of hydrocephalus, a disease in which fluid collects in the cavities of the brain. In Lower's time, it was thought that catarrh, an inflammation of the mucous membranes, might be caused by seepage of fluid from the brain to the nose.

In 1981, the MTA listed the station among the 69 most deteriorated stations in the subway system. Starting on March 2, 1998, the tunnel was reconstructed along with the cracked tunnel floor. This was done to correct a major water problem that had existed for many years due to the presence of the Harlem Creek and other underground streams, which caused extensive flooding, water damage, and seepage problems that occasionally contributed to severe service disruptions. The project cost $82 million and was finished on October 12, 1998.

The Mud Hole site is part of a series of submarine vents and thermal springs which produce "warm, chemically altered seawater from vents and seepage zones. The spring water apparently originates in the subsurface ocean around the Florida Platform and penetrates the highly porous strata of the platform about 500–1000 meters below sea level. It percolates toward the interior of the platform and is geothermal heated to about 40°C en route." The Mud Hole Submarine Discharge Zone is sometimes referred to as "Mud Boil".

The number of needles removed determines the water flow into the spillway. Gaps built into each bay allow limited seepage anytime the river level reaches the bottom of the bays. Removal of all 7000 needles takes about 36 hours but is usually done over a period of several days. The spillway is part of the United States Army Corps of Engineers' multi-state plan, called the Mississippi River and Tributaries Project (MR&T;), providing flood protection for the alluvial valley between Cape Girardeau, Missouri.

After closing it down, the city designated the site as an "ecology park" and began preparations to cover the mountain of garbage with trees. It is currently undergoing a land stabilization process that is expected to be completed by the year 2020. The walls were constructed deep into the ground to prevent the seepage of contaminated water into the Han River and streams. Methane and other gases were channeled into wells to provide heating to the World Cup Stadium and the surrounding residential district.

The mapping also found "pock marks" some deep by in diameter in the margins which may indicate methane seepage. The survey could support petrochemical exploration, though, Roberts et al. found evidence of "an extensive and effective petroleum system" to be "conjectural". Both the Otago and abyssal fans, and the rift itself developed from the Kaikoura Orogeny and were greatly accelerated after about 2.5 Ma, with the onset of global glacial/interglacial climatic cycles and the development of an icecap along the alpine region of South Island.

On 8 June 2010, the route between Sandton and OR Tambo International Airport in South Africa opened in time for the 2010 FIFA World Cup. The rest between Johannesburg Park Station and Rosebank was to be completed in 2011. This section was actually opened 7 June 2012, the delay caused by work to resolve a water-seepage problem in the single-track tunnel section between Rosebank and Park. Although railways in South Africa use the Cape gauge, Gautrain is built to the more expensive standard gauge of .

The health of the Wimmera River was expected to improve following the Wimmera-Mallee pipeline project that was completed in 2008. The project involved replacing old, inefficient stock-water supply and irrigation infrastructure, with a pipeline system. Prior to the project's completion, up to 90 percent of water extracted from the Wimmera River was lost through evaporation and seepage. The Wimmera-Mallee Pipeline system was expected to be many times more efficient and meant that there would be much less water extracted from the Wimmera River.

He was quickly followed by a rival, Edward L. Doheny, in the same year. Pearson's land surveys in the vicinities of Pedregal and San Cristóbal for the route of the Tehuantepec Railway had reported oil seepage from the ground, so in April 1901 he ordered his manager in Mexico to secure prospecting options on "...all land for miles around". Pearson built a refinery, pipelines and port facilities to handle the oil in 1905–06, but his company didn't make a major oil strike until 1908.

Many officials and scientists said at first the tar balls appearance might be a coincidence unrelated to the spill. Coal Oil Point is very close and well known for the offshore seepage of oil at about a day. Tar balls continued to show up on beaches farther down the coast in Los Angeles County including Malibu and the South Bay beaches on Santa Monica Bay. When tested, a tar ball recovered in the South Bay at Manhattan Beach matched the chemical signature of the spilled oil.

The surveyed length and depth of Booming Ice Chasm is 961 metres and 179 metres respectively and is ranked the 61st longest and 30th deepest cave in Canada. On the upper descending part of the cave, near the entrance, is a dense, steeply downward sloping sheet of ice, dropping approximately 140 metres. This is referred to as an ice fall or cascading glacier-like ice block and is controlled by cave morphology and the local climate. Specifically, it is formed by firn and seepage water.

The settled solids are anaerobically digested, reducing the volume of solids. The liquid component flows through the dividing wall into the second chamber, where further settlement takes place. The excess liquid, now in a relatively clear condition, then drains from the outlet into the septic drain field, also referred to as a leach field, drain field or seepage field, depending upon locality. A percolation test is required prior to installation to ensure the porosity of the soil is adequate to serve as a drain field.

Symptoms of pouchitis include increased stool frequency, urgency, incontinence, nocturnal seepage, abdominal cramping, pelvic discomfort, and arthralgia. Symptom severity does not always correlate with severity of endoscopically- or histologically-evaluated pouch inflammation. Additionally, these symptoms are not necessarily specific for pouchitis, as they may arise from other inflammatory or functional pouch disorders such as Crohn's disease of the pouch, cuffitis, pouch sinus, or irritable pouch syndrome. The most reliable tool for diagnosis is endoscopy combined with histologic features (derived from tissue biopsies obtained during endoscopy).

For example, the curvature of the Dalhousie and Strangways mound springs resemble the springs created by volcanic and tectonic fissures on Mars. Also, the Henbury craters resemble Martian craters; the Henbury craters have internal swamps and on Mars, there are signs of water seepage in the craters. There are 15 possible sites that may be used in Australia. These include Woomera, the Sturt Ranges, the Simpson Desert, the South Lake Eyre Basin, the Sturt Stony Desert, the Strzelecki Desert, and the North Flinders Ranges.

Ash ponds are generally formed using a ring embankment to enclose the disposal site. The embankments are designed using similar design parameters as embankment dams, including zoned construction with clay cores. The design process is primarily focused on handling seepage and ensuring slope stability. Failure of a pond's earthen embankment can cause ash spills on adjacent land and rivers, with serious environmental damage, as evidenced in the 2008 Kingston Fossil Plant spill in Tennessee and the 2014 Dan River coal ash spill in North Carolina.

Intense rains contribute to the seepage of waste deposits into the groundwater supply, generating and carrying the acid drainage from abandoned mines into the nearby rivers and streams. It increases turbidity and siltation, which in turn affects the food supply for the organisms in the affected areas. Seriously polluted sites may be environmentally hazardous despite the natural capacity of soils to reduce the solubility and bioavailability of toxic metals. Despite this capacity, environmental risks may persist at seriously polluted sites, including those that were abandoned decades ago.

In her second term, Diane co- authored the environmental bond referendums, which guaranteed a $100 million environmental bond for the county in 2006(she was also a co-author in the referendum which secured a $50 environmental bond in 2004). After several decades of neglect, Yatauro was instrumental in addressing the environmental problems facing the residents of The Birches, a community within Locust Valley. By helping to pass legislation for a pump station in the area, sewage seepage is now prevented from seeping onto local streets.

Most of the fort is in a very good state of preservation. In the portions that have fallen away (Haveli Man Singh) one can still see some part of the original construction. The central archway of the Chandwali Gate has been rebuilt recently so that is the only “fake” part of the fort. In early 2005, seepage, heavy rains, and general neglect caused the left inner face of the Talaqi Gate to collapse, and the right flank and foundation to become detached from the original structure.

Seepage in an upward direction reduces the effective stress within the soil. When the water pressure at a point in the soil is equal to the total vertical stress at that point, the effective stress is zero and the soil has no frictional resistance to deformation. For a surface layer, the vertical effective stress becomes zero within the layer when the upward hydraulic gradient is equal to the critical gradient. At zero effective stress soil has very little strength and layers of relatively impermeable soil may heave up due to the underlying water pressures.

Earth dams usually have a waterproof cutoff under their earthworks designed to stop seepage under the dam but it is doubtful whether there was any such a cutoff at Entwistle. The reservoir has a rock-cut outlet tunnel driven through the valley side rather than a culvert or pipeline and a siphon draw-off pipe. The dam is 108 ft high and 110 metres long at the crest. The present overflow channel and valve tower were added by the Bolton Corporation Water Works who took over the reservoir in 1864.

This well is credited as being the second well dug specifically for commercial oil drilling purposes in the United States. Despite drilling down 134 feet, nearly twice the depth of Drake's well, in an area Grandin had seen petroleum seepage at surface level, Grandin's first well was unsuccessful and dry. John Livingston then recruited his brother William James and after that first unsuccessful attempt, they dug several more wells that were then successful and turned extremely profitable. Around this time Elijah Bishop returned to Pennsylvania to join his brothers in their oil business.

Unlike other pluvial lakes, Lake Modoc had a steady inflow of surface water, owing to its proximity to snow- and glacier-covered mountains of the Cascade Range. Its watershed extended over present-day Modoc and Siskiyou counties (both in California), and Jackson, Klamath and Lake counties (all in Oregon), including the Williamson River, Sprague River and Lost River. Cinder, pumice and volcanic ash from the Cascades filled the lake. Lake Modoc also featured an outflow, at first to the south before a lava flow blocked it, although seepage continued from there to this day.

In the mid-19th century the body of water that is now the Lake Worth Lagoon was a freshwater lake. This had been named Lake Worth in honor of William J. Worth, commander of the Eighth Infantry Regiment in the Second Seminole War. There were no rivers or streams flowing into the lake; all of the flow into the lake was by ground seepage from the Everglades to the west. The only outflow from the lake was through a swamp that became the Lake Worth Creek as it approached the Loxahatchee River and Jupiter Inlet.
|
|
In 1866 travelers reported that fresh water was pouring out of the lake into the ocean at a point about ten miles south of the Jupiter Inlet. One report is that a settler named Lang had dug the channel to open an inlet, and it was known as Lang's Inlet for a while. This cut drained the lake down to sea level. The limited inflow of ocean water through the inlet and continued seepage of fresh water from the Everglades kept the lake from becoming more than mildly brackish.

Wrinkles from the rubber sheet can still be seen on the inside ceiling. The form was then removed, at which point that part of the roof (or floor) was finished. In theory, it should be possible to remove all cement from the entire building and have it continue to stand, since the only function of the mortar was to fill gaps and not to bear a load. Over 4,000 bags of cement were used, and in some places agricultural lime was used instead of sand for less water seepage.

It lives among the stones of the walls of the terraces and in crevices of limestone rocks. It loves the light and supports a few hours of sunshine in the early hours and tangential final hours of the day. It hates the rain directly on its fronds, preferring the moisture comes to its roots through the soil soaked by seepage of rainwater. For this usually grow well inside the crevices of the rocks and between the stones of the walls of the terraces, where no rain falls over.

The slopes of the mountainous land are very sparsely vegetated, with a steppe-type vegetation on plateaus. Groundwater seepage does occur in places along the Dead Sea shore, for example at the hot springs of Zara, which support a luxuriant thicket of Acacia, Tamarix, Phoenix and Nerium, and a small marsh. The less severe slopes of the reserve are used by pastoralists for the grazing of sheep and goats. The hot springs of Hammamat Ma'in lie close to the borders of the reserve are heavily used for tourism and recreation.

The lake was created by natural seepage from the underground aquifers, but the increase in well-drilling started to threaten that supply in the early 2000s. To compensate for this loss, and preserve the oasis as an destination for tourists, local business groups began pumping water into the lake in 2015.Desert Sun: "Costs of Peru's farming boom" It was announced in 2016 that the Peruvian scientist Marino Morikawa, who created a nanobubble system to decontaminate lake El Cascajo, will lead a project to restore the Huacachina lagoon.

Most of both the impervious core and the compacted sand shoulders of the dam embankment would be sourced from local materials of specific layers of soil. There would also be an deep cut-off wall under the concrete spillway and lock to reduce seepage. The plan to deal with the highly saline groundwater was to drill relief wells and drains, and pump it to evaporation ponds several miles away. This is similar to what has been done more recently at several points along the Murray for what are now known as "salt interception schemes".

The most complete fossils were encased in a residue which was almost completely calcite, indicating that the cave structures precipitated around their skeletons. The caves likely had to have been submerged in water (or at least persistently humid) for active speleotherm formation, and therefore this mode of spectacular preservation, to have been possible. Some fossils are encrusted by pyrite, indicating the presence of anoxic fluids or diagenesis in the systems at some point. Most (but not all) fossils are stained a dark color by seepage of hydrocarbons into the deposits.

Between 2010 and 2013 the lake shrank significantly, and by September 2013 the lake was reduced to a mere puddle with less than 2% of its original surface size. The exact causes for the water loss are unknown. The suspects are drought conditions and the thawing of an assumed permafrost layer under the lake leading to increased seepage. However, after the particularly wet winter of 2013/2014, the lake was back to around 75% of its original size by May 2014, and subsequently returned to its normal size.

Tate's Hell State Forest is 202,000 acres (819 km²) of land in Franklin and Liberty counties in Florida. The forest is located near Carrabelle off US 98 along the Gulf coast and on St. James Island. At one time, Tate's Hell supported at least 12 major habitats including: wet flatwoods, wet prairie, seepage slope, baygall, floodplain forest, floodplain swamp, basin swamp, upland hardwood forest, sandhill, pine ridges, dense titi swamp thickets and scrub. Tate's Hell State Forest is an important hydrologic area and includes a section of the New River (Florida Panhandle).

The lake has a surface area of and fills from a series of inflow channels from the southern and south western sides where Little Lake Parkeyerring is located. Shore seepage also occurs from shallow soils and rocky outcrops to the western side and the major outflow is through a channel along the north eastern side shore which discharges into the Coblinine River. Most of the catchment area has been cleared for agriculture. The area receives an average rainfall of approximately per annum, while the average evaporation is approximately per annum.

It is native to an area in the Kimberley region of Western Australia where it is commonly situated on undulating plains, rocky hills and ranges where it grows in red sandy or skeletal soils over quartzite or sandstone. The bulk of the population is found in coastal areas of the west Kimberley from around the Dampier Peninsula, on the Buccaneer and Bonaparte Archipelagoes in the north down to around Thangoo Station in the south where it is usually part of in woodland and shrubland communities sometimes in seepage areas.

Black Tern Bog State Natural Area is a Wisconsin Department of Natural Resources-designated State Natural Area featuring 20 acres (8 ha) of quaking sphagnum bog surrounding two small seepage lakes situated in a pitted outwash plain. The bog is rich in plant species, such as sundews, pitcher plant, bogbean, and bog rosemary, as well as three species of bog orchids: swamp pink, grass pink, and rose pogonia. The state-endangered bog rush (Juncus stygius) also grows here. Birds known to nest here include black tern, American bittern, killdeer, and mallards.

These terms generally mean the casket has a rubber gasket or other feature designed to delay water seepage and prevent rust. According to The Funeral Rule, these features may delay the decomposition of the remains, but they will not prevent it forever. Some caskets come with warranties, but the warranty is for the durability of the casket, not for protection from eventual decomposition of the remains. Under The Funeral Rule, no person selling any casket may claim that caskets with these features will prevent decomposition of the remains forever, because that is not possible.

Grassland on the Helvellyn range has been heavily overgrazed for many years, yet it supports a diversity of acid grassland species including sheep's fescue (Festuca ovina) on the summit ridge, matgrass (Nardus stricta) on the middle slopes, and fescue-bent swards on the lower slopes. The Nardus grasslands are the haunt of the scarce mountain ringlet butterfly (Erebia epiphron), the only alpine species of butterfly found in Britain. Acidic flushes (areas of water seepage) with their carpets of sphagnum mosses are common. Less common are basic flushes, which support a greater diversity of species.

The typical habitat conditions of small streams where the dace lives include: water supplied by clear, cool springs or seeps, absence of strong currents, effective cover like undercut banks and heavy brushy vegetation, and minimal large piscivorous fish populations. Small lake habitats also share these characteristics. Typically the lakes are clear and spring-fed with heavy vegetation (at least by shore) and few predatory fishes. However, in states where it is vulnerable or endangered, it can only be found in extreme head waters of clear streams and spring-fed seepage pools.

Illustration of AWD operation technique After the irrigation in the crop field, the water depth gradually decreases because of evapotranspiration, seepage, and percolation. Because of the installed tubes in the field, it is possible to monitor the water depth below the soil surface up to 15–20 cm. When the water level drops 15 cm below the soil surface, irrigation should be applied in the field to re-flood to a depth of 5 cm. During the flowering stage of the rice, the field should be kept flooded.

Wetlands require a shallow discharge of groundwater, it flows as a seepage into depressions in the land surface, in some instances wetlands feed off of perched groundwater which is groundwater separated from the regular water table by an impermeable layer. Marshes are a type of wetland and though not directly reliant on groundwater they use it as an area of recharge. Bogs, are also a type of wetland that is not directly reliant on groundwater but uses the presence of groundwater to provide the area with recharge as well as buoyancy.

Due to the steep gradient, seepage keeping the rails wet causing slippage, poor ventilation and planned duplication of the track, plans were drawn up to bypass the steep route. Trains commonly stalled in the tunnel for some time before having to back the locomotive out of the tunnel for another attempt. The tunnel was closed on 25 September 1913, and was utilised for growing mushrooms. In 1942, during World War II, the Royal Australian Air Force (RAAF) stockpiled bulk mustard gas stocks in preparation for a possible Japanese chemical weapons attack.

If the vents or ducts are held rigidly in place during this deflection, the result is usually the failure of the waterproofing layer. To avoid this difficulty, vents can be placed on other sides of the building (besides the roof), or separate segments of pipes can be installed. A narrower pipe in the roof that fits snugly into a larger segment of the building can also be used. The threat of water seepage, condensation, and poor indoor air quality can all be overcome with proper waterproofing and ventilation.

This level was not even half the reservoir's maximum capacity of . In 1993 and 1995, floods caused the lake to rise to within of the 1969 level. An inspection by the Bureau of Reclamation's Dam Safety Department revealed that the dam could potentially fail if the deficiencies were not corrected. As a result, eight relief wells (wells that drain a pervious stratum) were installed in the dam in 1995, and a heavy gravel filter blanket to prevent erosion of embankment materials during seepage was constructed in the spring of 1996.

Instead, the water is lost through evaporation or ground seepage. Optimal landscaping techniques and minimal landscaping are two major reasons why casinos are able conserve water. Properties have reduced indoor water use by installing low-flow showerheads, retrofitting toilets, educating employees about conservation techniques, and setting overall water-use goals. Approximately 3 to 4 percent of the total water is actually consumed by casinos.. In 2017, most of the major casino companies had a recycling rate of more than 40 percent, compared with the 20 percent recycling rate in Clark County.

There was very little seepage into the tunnels, a natural consequence of excavation in clay, but any water that did find its way in was quickly pumped up to the sewers above. Ventilation was natural, relying primarily on the piston effect of trains pushing through the tunnels to circulate the air. While buildings with deep subbasements could connect directly to the tunnel, connections to surface level and shallow basements were by elevator shafts. George W. Jackson, the contractor who built the tunnel system, received several patents related to building such shafts.

After the leakage was discovered, the Sabal Company installed containment booms at the site and posted a vacuum truck to capture the mud seepage. The spill prompted protests from concerned local citizens on November 16, 2016. As part of the company's biweekly report for the week ending on November 27 to the Federal Energy Regulatory Commission, it was reported that a sinkhole had developed southeast of the horizontal directional drilling (HDD) hole exit point at the work site near the Withlacoochee River. The sinkhole had been identified on November 5 by workers in the field.

During a recent scanning of the Mullaperiyar dam using a remotely operated vehicle by the Central Soil and Materials Research Station on directions from the Empowered Committee of the Supreme Court, the Kerala Government observer opined that "mistakes in the strengthening works carried out by Tamil Nadu" in 1979 damaged the masonry of the dam. Current safety concerns relate to several issues. Since the dam was constructed using stone rubble masonry with lime mortar grouting following prevailing 19th-century construction techniques that have now become archaic, seepage and leaks from the dam have caused concern.

Sarracenia habitats in the southeastern Coastal Plain consist primarily of fire-maintained pine savannas, wet prairies, or seepage bogs. Without frequent fire (1-3 years), these habitats undergo ecological succession and are quickly invaded by woody shrubs and trees, which eliminate Sarracenia by increasing shade and reducing soil moisture. In several cases, carnivorous plant enthusiasts have introduced S. purpurea into suitable habitats outside of its natural range, where it has naturalized. Some of these populations are decades old; the oldest known occurrence in the Swiss Jura mountains is around one hundred years old.

The tower (Minot's Tower) and west nave were rebuilt between 1362 and 1370, following a fire. The name commemorates Thomas Minot, Archbishop of Dublin 1363–75, who oversaw the rebuilding. From the very earliest years there were problems with seepage of water, with a number of floods, especially in the later years of the 18th century, caused by the surrounding branches of the River Poddle – even in the 20th century, it is reported that the water table was within 2.3 metres (7.5 feet) of the floor.Bernard, 1924: p.

Having no surface inlet, the lake receives water naturally only from rain, surface runoff, and groundwater seepage. In addition, water from municipal wells is sometimes pumped into the lake during the dry season; otherwise the lake level might fall as much as in late summer. Three small ponds, connected to the lake and to one another by culverts, lie just north of the lake at its west end. Outflow from lake and ponds occurs only when workers release water through a concrete weir to Salmon Creek, in a separate drainage basin to the east.

Olallie Butte is a steep-sided shield volcano in the Cascade Range of the northern part of the U.S. state of Oregon. It is the largest volcano and highest point in the distance between Mount Hood and Mount Jefferson. Located just outside the Olallie Scenic Area, it is surrounded by more than 200 lakes and ponds fed by runoff, precipitation, and underground seepage, which are popular spots for fishing, boating, and swimming. The butte forms a prominent feature in the Mount Jefferson region and is usually covered with snow during the winter and spring seasons.

Fed by runoff, precipitation, and subsurface seepage, Olallie Lake otherwise has no clear source of inflow or outflow, nor do many other lakes in the Olallie Butte area. To maintain Olallie Lake's water level, a low dam was built on the Mill Creek outlet, which flows east to Long Lake. Shitike Creek heads between Olallie Butte and Mount Jefferson, coursing east to the Warm Springs community before it joins the Deschutes River. Usually covered with snow in the winter and spring seasons, Olallie Butte is a prominent feature in the Mount Jefferson region.

Because of its highly permeable nature, the San Joaquin River's valley is underlain by one of the largest aquifers in the Western United States. The aquifer underlying the San Joaquin River and Tulare Basin is estimated to hold nearly of water, of which about half can be pumped economically or is clean enough for human use. The aquifer receives in excess of of inflow per year, mostly from precipitation and irrigation water seepage. Concentration of chloride and other minerals generally increases from east to west across the basin.

In May 1952, Memorial Field, to be dedicated to the Putnam Lake casualties of World War II, was proposed to replace the swimming pool, which had not been used since the early 1930s because it was contaminated with seepage and infested with leeches. Construction proceeded through the leadership of Henry Sherer, and in 1955, Edward Angerola, chairmen of the Memorial Field committee. Tiles were used to divert water running through the ground, and fill was brought in from the land surrounding the firehouse. Memorial Field's baseball diamond and field is used in the warmer months.

This bulge is the result of the creation of a false lumen due to the vast amount of blood seepage from the aortas and surrounding veins. In some cases it is not uncommon to see degeneration in the ascending and descending aorta and the atrioventricular and semilunar valves due to elastolysis or breakdown and loss of elastic fibers. These connective tissue malfunctions are traceable to mutations, and lack of genes encoding for important components such as collagens, and micro- fibril-associated glycoproteins. Breakdown among these connective layers eventually compromises the integrity of the aortic lumen.

Paulina Lake is one of the twin crater lakes in Newberry Crater, central Oregon, United States (the other being East Lake). It is located above sea level in the Newberry National Volcanic Monument near La Pine. The lake's primary inflow is seepage from East Lake, snow melt, and hot springs, and its outflow is Paulina Creek, a tributary of the Little Deschutes River. It has an area of , a volume of , a maximum depth of , a shore length of about , and a residence time of about 46 years.

After three hours, the dam breached, with a total release of , resulting in five deaths and the destruction of 277 homes. Vigorous rescue efforts averted a greater loss of life. The reservoir was constructed on a low hilltop between 1947 and 1951 by the Los Angeles Department of Water and Power, directly on an active fault line, which was subsidiary to the well-known nearby Newport–Inglewood Fault. The underlying geologic strata were considered unstable for a reservoir, and the design called for a compacted soil lining meant to prevent seepage into the foundation.

Karst formations are created when limestone bedrocks are, over time, attacked by water through natural precipitation seepage. The rain or snowmelt water contains dissolved carbon dioxide from the atmosphere, which, in solution, forms a weak carbonic acid. That acid attacks the limestone rock dissolving it and thereby leading to the voids within the rock formation. When a reservoir of 100+ feet in elevation is raised above this style of foundation, the hydraulic pressure of the water easily dislodges the cementing clays that are in the cracks and void spaces of the underlying Karst foundation.

The chhatris on the four corners are octagonal. The palace had suffered subsidence in the past and also partial seepage (plasterwork and wall damage equivalent to rising damp) because of waterlogging, which have been repaired under a restoration project of the Government of Rajasthan. The hills surrounding the lake area, towards the north east of Jaipur, have quartzite rock formations (with a thin layer of soil cover), which is part of the Aravalli hills range. Rock exposures on the surface in some parts of the project area have also been used for constructing buildings.

Glen Canyon Dam The Glen Canyon Dam has been proposed for removal because of the negative effects it has on the water quality and riparian habitat of the Colorado River in Grand Canyon National Park. In addition, the reservoir impounded behind it, Lake Powell has filled all of the canyons for up to above the dam. This lake, while providing recreational opportunities, has eliminated more than of habitat for endangered Colorado River fish species. The reservoir also loses more than 6 percent of the total annual flow of the Colorado River to evaporation and seepage.

Outgassing (sometimes called offgassing, particularly when in reference to indoor air quality) is the release of a gas that was dissolved, trapped, frozen, or absorbed in some material., Chapter 3 Outgassing can include sublimation and evaporation (which are phase transitions of a substance into a gas), as well as desorption, seepage from cracks or internal volumes, and gaseous products of slow chemical reactions. Boiling is generally thought of as a separate phenomenon from outgassing because it consists of a phase transition of a liquid into a vapor of the same substance.

One was approximately fifty-eight feet west of the outlet gates and another about the same distance to the east. Mulholland, along with his Assistant Chief Engineer and General Manager Harvey Van Norman, inspected the cracks and leaks and judged them to be within expectation for a concrete dam the size of the St. Francis. At the beginning of April, the water level reached the area of the inactive San Francisquito Fault line in the western abutment. Some seepage began almost immediately as the water covered this area.

Approximately 92% of households on Fongafale islet have access to septic tanks and pit toilets. However these sanitary facilities are not built as per the design specifications or they are not suitable for the geophysical characteristics, which results in seepage into the fresh water lens and run off into coastal waters. On Funafuti and on the other islands, rainwater collected off the corrugated iron roofs of buildings is now the primary source of fresh water. On Funafuti a desalination unit that was donated by Japan in 2006 also provides fresh water.

The imitator salamander is not toxic, but is thought to be a Batesian mimic of the red-cheeked salamander (Plethodon jordani), a noxious species. Specimen showing mimicry of the red-cheeked salamander Adult imitator salamanders hide during the day and emerge at night to forage for small invertebrates. They are probably preyed on by birds, mammals, snakes and the spring salamander (Gyrinophilus porphyriticus). The imitator salamander breeds in summer and a clutch of about 20 eggs is laid and attached to the underside of a rock in a seepage or other wet location.

The taxpayer-funded (c. $900m to about a billion dollars) remediation plan to permanently freeze the underground arsenic trioxide dust chambers was approved by the Canadian federal government in August 2014. According to the federal civil servant in charge of the clean- up, Jane Amphlett, using technology like that used in ice-hockey rinks, coolants will permanently freeze the storage chambers containing the arsenic trioxide dust to keep groundwater seepage out in what is called the "Frozen Block Method." A Yellowknife community museum is envisioned for part of the former Giant Mine townsite.

State Route 178, which travels through the canyon between Bakersfield and Lake Isabella, became unstable, and one lane was closed due to the high water levels.Kern Valley Sun, Canyon road along river cracks, May 17, 2006 Some flooding was reported by property owners along the river. Emergency management officials warned that if Isabella Dam were to fail when the reservoir was full, a large part of Bakersfield would be inundated within 2 to 4 hours. After the news of the seepage, the dam came under further attention due to being situated on a fault line.

The flooding revealed that although these properties were not normally affected by floods, there was significant seepage through the banks. There was no likelihood of sufficient money being available to buy all the houses to demolish them, and so a program of constructing concrete cores in the centre of the banks began in 1956 and continued until 1964. Rainfall in October 1960 was even heavier, when fell on the Somerset Levels, representing 249% of the normal levels. Again the valley flooded, and large areas of Taunton were under water to a depth of .

This was done to correct a major water problem that had existed for many years due to the presence of the Harlem Creek and other underground streams, which caused extensive flooding, water damage, and seepage problems that occasionally contributed to severe service disruptions. The project cost and was finished on October 12, 1998. During the reconstruction, 3 trains were rerouted to the 137th Street–City College station on the IRT Broadway–Seventh Avenue Line. Supplemental shuttle bus service connecting to other lines in the area were provided for much of this time.

Thus, the seeming division between innate immunity and acquired immunity is more practical than natural. Immunology's early feuds over whether immunity is innate or is acquired reflected limited perspectives. Sharing Pasteur's view of science as a means to suppress the problems plaguing humankind, Metchnikoff brought into France its first cultures of yogurt for probiotic microorganisms to foster health and longevity by suppressing the colon's putrefactive microorganisms alleged to foster the colon's toxic seepage, autointoxication. As the 20th century opened, British surgeons were still knife-happy, and called for "surgical bacteriology".

Afterward, the dam project's operation was turned over to Gunma Prefecture, rebranded as the auxiliary "Akaya River Cumulative Project"; construction began in 1952, and completed in 1956. However, during initial impoundment (in which the dam is partially filled to test for abnormalities), leakage through the bedrock on the left bank was discovered, and Gunma Prefecture requested repairs from the Ministry of Construction. That same year, concrete work was started to enable seepage control on the left bank. Repairs were completed three years later in 1959, and construction was finalized.

In the early 1900s, Price Creek was a clear stream until it arrived at the Johnson Colliery, where mine water and waste water was drained into it. From this point downstream to its mouth, the creek's streambed was full of a type of anthracite known as culm. The tributary Pancoast Creek is unaffected by culm, but it was affected by streams of surface water and sewage. A mid-20th-century report estimated the volume of surface seepage into mine workings at Price Creek was 4.22 gallons per minute per inch of rainfall.

Sea cliff erosion is a large source of sediment to many coastal sedimentary budgets, initiated by many different processes including wave attack, rainfall and groundwater seepage. Cliff erosion can be influenced by rising sea levels and is magnified with storm surge events. An example of cliff erosion is the erosion of large Pleistocene alluvial fans that span the length of the Canterbury Bight, situated north of the Waitaki River in New Zealand. The erosion of these cliffs, due to high energy wave environments contributes 70% of the overall material supplied to these beaches.

Lacustrine system of the Mojave Desert The size of pluvial lakes, such as Lake Manly, is governed by the balance between inflow by precipitation or rivers or streams and evaporation, if one assumes that seepage and overflow are not important. This can make the surface of such lakes a useful gauge for paleoclimatic conditions. The principal water supplies to Lake Manly were the Amargosa River, the Mojave River and the Owens River, which yielded a large integrated drainage system over the southwestern Great Basin. The total surface area of Lake Manly's catchment was about .

These bones had to be moulded and reconstructed by the Taxidermist with a bone-like substance, which was a very costly affair. The other bones were cleaned and treated in huge containers filled with water and enzymes. This process took about two years to rid the bones of excess oil so that no major oil seepage will occur after the skeleton is hung. After three and a half years, these bones were then cleaned, prepared and assembled by the taxidermist and are now hanging in the Whale House.

High- resolution seismic profiles near the shelf edge show evidence of near-surface slumps and faulting in the subsurface and concentrations (about ) of methane gas. Several studies (e.g., Amazon Shelf Study—AMASEDS, LEPLAC, REMAC, GLORIA, Ocean Drilling Program) indicate that there is evidence for gas seepage on the slope off the Amazon fan based on the incidence of bottom-simulating reflections (BSRs), mud volcanoes, pock marks, gas in sediments, and deeper hydrocarbon occurrences. The existence of methane at relatively shallow depths and extensive areas of gas hydrates have been mapped in this region.

Moonshine Hill is an area in Houston, Texas, United States that was once a distinct Harris County community located on the Humble oilfield. Moonshine Hill began as a result of an oil boom and was located 2 miles east of Humble in northeastern Harris County off of FM 1960. Gas seepage were first noticed in 1887 by James Slaughter, who, in cooperation with S.A. Hart, unsuccessfully drilled for the commodity. In 1903 the Houstonian Charles F. Barrett took a lease at Moonshine Hill which is now part of Farm Road 1960.

Removal of the cyst results in irreversible damage to the intersecting spinal nerve. Although fibrin-glue therapy initially had been thought to be a promising therapy in the treatment of these cysts, there have been multiple problems associated with the fibrin glue therapy including seepage of fibrin. It is no longer recommended for use at present by the Health Department in some countries and neurosurgeons previously performing the procedures. Nevertheless, all types of surgical treatment pose common risks, including neurological deficits, infection and inflammation, spinal headache, urinary disturbances, and leakage of cerebrospinal fluids.

The Mukurumudzi Dam is a 24m high homogeneous earthfill dam, with a low permeability central core and cut-off key and grout curtain, to limit seepage under the dam. The outlet works comprise a reinforced concrete intake tower and a reinforced concrete draw-off culvert and associated pipe work. The dam embankment consists of of silty-sand originating from the local area. Due to a lack of suitable clay materials in the area, an impermeable central bentonite- cement-soil cut-off membrane was constructed successively with the embankment.

Within the ovary, fungal mycelia form a white cottony mass in each of the four locules, or fruit seed cavities, and grow into the fleshy fruit tissue. The infected berry itself remains firm, categorizing this type of rot as a hard rot (a soft rot is characterized by total tissue maceration and seepage). Eventually, the fungus consumes the fruit pericarp and a hard black pseudosclerotium (mummy) develops from 25 – 50% of the diseased fruit. Mature pseudosclerotia often float and may be dispersed by harvest or cold protection floods.

Characteristic landforms caused by groundwater sapping are “theater-shaped” channel heads and “U-shaped” valleys, which have a consistent width and steep valley walls. Weakened basal rocks are unable to support more resistant upper layers, causing valley head and sidewalls to collapse inwards. Theater-shaped channel heads are characterized by overhanging sidewalls that are relatively dry compared to the lower level rocks below the zone of seepage. The development of theater heads has been related to “ground-water flow direction, jointing and faulting, permeability contrasts, formation slope and dip angles, and formation cohesion”.

Seepage from the Tailings Storage Facility at the mine have been detected in the nearby Surprise Creek. Monitoring in 2005, 2007 and 2010 shows that soluble sulfate, zinc and, potentially, lead and cadmium are seeping into Surprise Creek. Dust from operations at the run of mine pad and crushing plant is contaminating stream sediments in both Barney Creek and Surprise Creek, affecting macroinvertebrate species. An extreme risk of embankment failure, or "overtopping", of the spillway in the Tailings Storage Facility due to water volumes has also been identified, requiring immediate action.

Only a few small tributaries bring water to the lake; most of the water comes from a 5 m deep spring which is located at the narrowest part of the lake. All the water from the outflow of the lake ends in seepage at the end of the Lödensee after it has gone through Mittersee. Geological research showed that the water finds its way under the Hochgern mountain to the bog near Bergen, Upper Bavaria. The lake with its beach, the clean water and the distance to the next village attract many people in summer.

Below the base course are the binder course, and the cement-treated base. Detailed investigations found that water seepage was evident along the rims of the expansion joints in the cement-tested base, indicating that a large quantity of water was still trapped in the sand blanket (the bottom-most layer of the tarmac). It was found that water trapped in the sand blanket was fully confined with no connection to the pavement areas of the airport. A later investigation by the AOT identified several potential reasons for the trapped water in the sand blanket.

There is also evidence of the use of explosives during construction and/or maintenance of the race in the form of blasting scars on rock faces along the race. In the midsection of the race (north of Shipton's Flat) there is some evidence of stone pitching. A second race of slightly smaller dimensions is constructed a consistent below the main race to catch overflow or seepage. While the intake point at the head of Parrot Creek was not surveyed, approximately north-west the race passes through a bedrock tunnel situated in dense rainforest.

Water abstraction for irrigation is another threat for this fish, especially when there is low water or drought. Oil seepage from equipment and vehicles could harm the blackstripe topminnow because of its habit of feeding at the surface of the water where slicks occur. First designated as a species of Special Concern by COSEWIC (Committee on the Status of Endangered Wildlife in Canada) in April 1985, its status was re-examined and confirmed in May 2001 and May 2012. The blackstripe topminnow is now listed in Canada under the federal Species at Risk Act (SARA).

The First Day School building was completed in 1987, with full modern amenities, on the site of a former horse stall. During the week it was used by a local nursery school. That same year, Amawalk had enough members to become a monthly meeting again. In 1993, four years after the property was listed on the National Register, the meeting secured a $50,000 matching grant from the state's Historic Preservation Office to renovate the interior of the building, which had suffered from insect infiltration and water seepage over the years.

According to the EPA, residential mold may be prevented and controlled by cleaning and repairing roof gutters, to prevent moisture seepage into the home; keeping air- conditioning drip pans clean and drainage lines clear; monitoring indoor humidity; drying areas of moisture or condensation and removing their sources; ensuring that there is adequate ventilation by installing an exhaust fan in your bathroom; treating exposed structural wood or wood framing with an EPA- approved fungicidal encapsulation coating after pre-cleaning (particularly homes with a crawl space, unfinished basement or a poorly-ventilated; attic).

The EPA team returned in July 2015 to continue the work. They found that a landslide had covered the drainage pipes. When the slide was cleared, seepage was again observed at a level about above the bottom of the mine entrance, which they thought was the level of pooled water behind the plug. They planned to excavate the entrance beginning from the level of the top of the mine tunnel down to what they took to be the top of the water, insert a pipe through that clearance, and drain the pooled water.

It is claimed that the Yanar Dag flame was only noted when accidentally lit by a shepherd in the 1950s. There is no seepage of mud or liquid, which distinguishes it from the nearby mud volcanoes of Lökbatan or Gobustan. On the territory of Yanar Dag, State Historical- Cultural and Natural Reserve was established by the Presidential decree dated 2 May 2007 which operates under the control of State Tourism Agency of Azerbaijan. After major overhaul between 2017-2019, Yanardag Museum and Yanardag Cromlech Stone Exhibition were launched in the area of the Reserve.

The site was declared a National Historic Landmark in 1989. One of the site's unusual features is a series of pits that were apparently used for leaching tannin from acorns. These pits, as well as associated features, including basketry weave patterns, bear resemblance to finds at other sites on the Pacific coast of North America, and in Japan, representing a rare direct connection between North American and Asian cultures. The site has been a site of interest to amateur collectors since at least the early 20th century, and came under further threat in the late 20th century by seepage from a nearby levee.

Muddy river Nonpoint source (NPS) pollution is pollution resulting from many diffuse sources, in direct contrast to point source pollution which results from a single source. Nonpoint source pollution generally results from land runoff, precipitation, atmospheric deposition, drainage, seepage, or hydrological modification (rainfall and snowmelt) where tracing pollution back to a single source is difficult. Nonpoint source water pollution affects a water body from sources such as polluted runoff from agricultural areas draining into a river, or wind-borne debris blowing out to sea. Nonpoint source air pollution affects air quality, from sources such as smokestacks or car tailpipes.

The global retention time for a lake (the overall mean time that water spends in the lake) is calculated by dividing the lake volume by either the mean rate of inflow of all tributaries, or by the mean rate of outflow (ideally including evaporation and seepage). This metric assumes that water in the lake is well-mixed (rather than stratified), so that any portion of the lake water is much like any other. In reality, larger and deeper lakes are generally not well-mixed. Many large lakes can be divided into distinct portions with only limited flow between them.

L. reflexum is an endemic species that is only found in the east of the Cederberg mountains between Wupperthal in the south to the Pakhuis Pass in the north. It occurs between 900–1800 m (3000–6000 ft) altitude. The annual rainfall in its range is 250–380 mm (10–15 in), mainly during the winter. Due to the area's dry climate and its preference for relatively moist conditions, it grows mainly in locations such as in seepage areas or along streams, where it is often in the company of the reed-like restionid Cannomois virgata and common bracken Pteridium aquilinum.

CGI-enhanced scene Digital Domain handled most of the film's 200+ effects shots, including pools of blood and bloody fingerprints found at crime scenes. For the murder of Cecelia Shepard at Lake Berryessa, blood seepage and clothing stains were added in post-production. Fincher did not want to shoot the blood with practical effects because cleaning the costumes after every take would take too long, so the murder sequences were done with computer-generated (CG) blood. CG was also used to recreate the San Francisco neighborhood at Washington and Cherry Streets where cab driver Paul Stine was killed.

Such canyons (with rounded headwalls and no obvious overland infeeders) have been widely presumed to have formed by a process of seepage erosion. However, it has been suggested that this side canyon was formed by a catastrophic flood event (Lamb, 2008). The case is supported by comparison with Box Canyon, Idaho, USA, which shows a similar morphology, but also exhibits features such as plunge pools, rock scours on the headwall rim, and a notch on the headwall rim, suggestive of large-volume flow. The Mamers Valles were named in 1976, after the Oscan word for Mars.

New mudflows spots begun in April 2010, this time on Porong Highway, which is the main road linking Surabaya with Probolinggo and islands to the east including Bali, despite roadway thickening and strengthening. A new highway is planned to replace this one however are held up by land acquisition issues. The main railway also runs by the area, which is in danger of explosions due to seepage of methane and ignition could come from something as simple as a tossed cigarette. As of June 2009, the residents had received less than 20% of the suggested compensation.

The pampas on the right bank is in the same place in all photos, but the lake has grown as the sand has further blocked its valley and extra sand has covered some of the cabbage trees. Brown clay underlies the dunes,NZ Dept of Scientific & Industrial Research – Geology of Ironsand Resources of NZ, David Kear, 1979 which limits the rate of seepage through the dunes, thus forming lakes where dune advance has blocked valleys. The lake bed and stream are on Awhitu sands. They are about a million years old and made up of pumiceous cross bedded brown and yellow clayey sands.

In 1934, the U.S. Bureau of Reclamation initiated construction on the Grand Coulee Dam on the Columbia River about north of the Drumheller Channels. Grand Coulee was only one part of the Columbia Basin Project, which included four major storage reservoirs, hundreds of pumping plants, of canals and laterals to irrigate the region. Irrigation began in 1951, raising the water table. By 1980, when the last stage of the project was completed, the area of wetlands in the Columbia Basin was at least 20 times larger than it had been earlier as a result of seepage and a raised water table.

19 Although Avila Beach still has a working commercial fishing pier and the inland areas have extensive apple orchards, tourism is now the main industry. There are few historical structures remaining; among the oldest is the Point San Luis Light, built in 1890 after a series of shipping accidents. In the late 1990s, Unocal began the cleanup of decades old oil seepage discovered years earlier from corroding pipes under the township, and which had caused a massive oil spill under the town. Over 6,750 truckloads of contaminated material was sent to a Bakersfield landfill, and replaced with clean Guadalupe Dunes sand.

The issuance of oil at the Young Well is believed to be the result of an underlying fault. Although secondary to the larger Absaroka Fault, it is substantial enough to permit the ascension of petroleum from oil shale. Both Hilliard Flat wells yield heavy crude oil; a 1905 survey suggested that it is derived from the same source as the a region's lighter Benton oil and proposed that the lighter content of the Hilliard Flat oil evaporates before it reaches the surface. This survey observed that oil seepage was then limited to just a few gallons per day.

The situation may be unique to the individual affected, but it may not be unique to the life of the group, the community, of which he is a part. Thus, in Arundell's view, even if the basement sealing expense was not ordinary in the sense that it was unique expense in the life of Midland as an individual, it still could be "ordinary" within the meaning of 23(a) because taking steps to protect a business from the seepage of oil to protect one's property was a common, normal thing for businesses to do in general.

The canal connected the waters of Lake Erie to the tidewater of New York harbor in a multi-level route that followed the local terrain and was fed by local water sources. All of the New York branch canals would follow this model. With the Erie, as with all of the branch canals, water flow was required for several purposes: filling the canal at the beginning of each spring season; water for lockage, i.e., water loss from higher to lower levels; water loss by seepage through the berm and towpath banks and water diverted for industrial power usage.

In 1937, after noticing a drop in groundwater, Samuel Poorman negotiated a settlement with the MWD for the loss of groundwater, but instead of taking cash, the Poormans took their share in water. The settlement was negotiated in secret and included two additional landowners. The Pico family, owners of a 3,200 acre (13 km2) ranch southwest of the Poorman's ranch, also agreed to take water in return for dropping their claim against the MWD. Dairy farmer Clayton Record Sr. agreed to take five percent of the seepage water in exchange for right of way across his property.

The floors and walls of the channels were lined with cement and the roof was usually a vault. The cement was usually as high as the water would reach, which was meant to be about a half to two thirds full. Lining the walls and floor with cement served three purposes, protect against leaks and seepage, to provide a smooth contact surface, and to make the contact surface continuous and joint free from one end to the other. In order to maintain the slight downward gradient, the aqueducts didn’t follow a direct route to Rome but instead used the lay of the land.

To prevent Munich's historic town hall, located above the station and in between its two tunnels, from sinking in during the construction works, the ground surrounding the construction site had to be frozen over. The construction was completed in time for 2006 World Cup. ; Karlsplatz (Stachus) (U4/U5) — Completed Renovated Karlsplatz (Stachus) mezzaine level The two mezzaine levels and north entrance were renovated to include the enhanced fire protection and the updated interior. Due to the damage from humidity and water seepage, the structures of U4/U5 platforms were repaired and sealed up against further seepages.

During the 20th century, the citadel witnessed significant urban and social changes. A high steel water tank was erected on the citadel in 1924, providing the inhabitants with purified water, but also causing water damage to the foundations of the buildings due to increased water seepage. The number of inhabitants gradually declined over the 20th century as the city at the foot of the citadel grew and wealthier inhabitants moved to larger, modern houses with gardens. In 1960, over 60 houses, a mosque and a school were demolished to make way for a straight road connecting the southern gate with the northern gate.

Visitors at the Snow World A gigantic Two-hundred tonnes of artificial snow was laid on the layered flooring which was specially prepared to avoid seepage or melting. Every day, the top layer of snow is cleaned and an additional two to three tonnes of snow, which is generated within the facility, is used to top the snow spread. The artificial snow is made using a patented technology from Australia. The snow is made from water that is filtered four times so it won't harm children if they consume it, as they are prone to in other such locations.

A study of the cationic, alkaline polymer SS299 (a commercially produced additive) found that the properties of treated soils depend on the plasticity index of the original soil, which reflects its clay content. Hydrogel swelling of biopolymers reduces the amount of soil pore space, restricting the flow of water and suiting polymer hydrogels for construction projects seeking to minimize water seepage and support vegetation growth. Biopolymers can be added to soils along with synthetic polymers to utilize the properties of both polymers. By increasing the water retention and infiltration rates in soils, the addition of biopolymers increases the availability of water for plants.

Six thousand years ago Reedy Lake was part of a large marine bay. With a subsequent change in relative sea level it was cut off from the sea by a barrier of sand dunes, and its bed covered by a layer of alluvial clay deposited by the Barwon River. Before European settlement of the area in the early 19th century the lake was an ephemeral wetland that became saline in summer from the seepage of salty ground-water and occasional exceptionally high tides. In winter it usually became fresh, as river floods flushed out the saline water.

The upper section was cut through limestone, and Farlough Lake, one of the canal's water sources, could not supply sufficient volumes of water to overcome seepage. Additionally, the inclines had been made too steep for the counterbalance mechanism to work well. In 1787, when an engineer called Richard Owen was sent by the Corporation for Inland Navigation to inspect the route, he found the hurries suffering from mechanical failure and little water in the upper section. He suggested the replacement of the tub boats by flat-bottomed barges on each level, , each of which would carry two rows of seven wagons.

Many factors impact the shape and color of speleothem formations including the rate and direction of water seepage, the amount of acid in the water, the temperature and humidity content of a cave, air currents, the above ground climate, the amount of annual rainfall and the density of the plant cover. Most cave chemistry revolves around calcium carbonate (CaCO3), the primary mineral in limestone and dolomite. It is a slightly soluble mineral whose solubility increases with the introduction of carbon dioxide (CO2). It is paradoxical in that its solubility decreases as the temperature increases, unlike the vast majority of dissolved solids.

For example, in New Mexico, surface and ground water have been managed together since the 1950s. This trend comes from a growing scientific understanding of the formerly mysterious behavior of underground water systems. For instance, gradual contamination of some water supplies with salt has been explained with the knowledge that drawing water from a well creates a gradual seepage into the well area, potentially contaminating it and surrounding areas with seawater from a nearby coast. Such knowledge is useful for understanding the effects of human activity on water supplies but can also create new sources of conflict.

The smooth snake is also found in the areas of wet heath which occur mainly at the foot of the hill and are created by seepage and flushes from below the hill's water table; and where free draining gravelly soils meet less permeable clay. Rare flora found in these areas include bog asphodel (Narthecium ossifragum), hare's-tail cotton- grass (Eriophorum vaginatum), bog moss (Sphagnum), the carnivorous sundews Drosera intermedia and Drosera rotundifolia, and pale butterwort (Pinguicula lusitanica). Conifers and Rhodedendron dominate the western slopes. Coniferous woodland dominates the top and western slopes of the hill and comprises mostly maritime and Scots pine.

Aquifer tests and well tests can be used with Darcy's law flow equations to determine the ability of a porous aquifer to convey water. Analyzing this type of information over an area gives an indication how much water can be pumped without overdrafting and how contamination will travel. In porous aquifers groundwater flows as slow seepage in pores between sand grains. A groundwater flow rate of 1 foot per day (0.3 m/d) is considered to be a high rate for porous aquifers, as illustrated by the water slowly seeping from sandstone in the accompanying image to the left.

This signified the completion of one of the largest public works projects in Victorian history, which had been undertaken over a period of almost twenty-five years. Arts Centre Melbourne is unusual in that its theatres and concert hall are built largely underground. Hamer Hall, situated closest to the river, was initially planned to be almost entirely underground, thus providing a huge open vista between the theatre spire, the river and Flinders Street railway station. However, construction problems with the foundations, including water seepage, meant the structure had to be raised to three storeys above ground.

In September 2016, construction began on the pipeline. On November 12, 2016, fourteen protesters were arrested at a pipeline construction site in Gilchrist County, Florida after one protester locked himself to truck on site and the others obstructed its path. They had been inspired by the Dakota Access Pipeline protests and used similar protest signage. In late October 2016, drilling mud seepage began leaking into the Withlacoochee River at construction along the border of Brooks County, Georgia and Lowndes County, Georgia from a pilot hole that had been drilled underneath the river in preparation for the horizontal directional drilling hole.

Later development blocked the lake's only outflow, leaving it endorheicWhile the word "endorheic" has not been used to describe the lake, Woodall and Healey described it as having only seepage as its outflow, and later sources (such as Carleton) note that the 1970s construction of the causeway blocked the only outlet. and complicating the problems caused by earlier pollution. By the early 1970s it no longer supported any fish; within two decades residents had stopped swimming or boating it out of fear of leeches. Subsequent studies have shown that the lake completely eutrophied sometime in the mid-1990s.

New York County Courthouse Interior Designation Report , New York City Landmarks Preservation Commission (March 24, 1981). Accessed September 2, 2011. Restoration of the mural (along with a stained-glass window also by Pusterla) took place in 1988; the project received a 1989 Design Award from the Public Design Commission of the City of New York. The restoration project, which was privately funded by money raised from New York City judges and attorneys, was part of a broader renovation campaign in the 1980s and 1990s to protect the courthouse's historic art from water seepage and other damage caused by neglect.

This station opened just after midnight on November 23, 1904, as part of the IRT's original system. It was completed along with the rest of the IRT Lenox Avenue Line, then known as the East Side Subway or East Side Branch, south of 145th Street. Starting on March 2, 1998, the tunnel was reconstructed along with the cracked tunnel floor. This was done to correct a major water problem that had existed for many years due to the presence of the Harlem Creek and other underground streams, which caused extensive flooding, water damage, and seepage problems that occasionally contributed to severe service disruptions.

In most cases the hematoma such as a sac of blood eventually dissolves; however, in some cases they may continue to grow such as due to blood seepage or show no change. If the sac of blood does not disappear, then it may need to be surgically cleaned out/repaired. The slow process of reabsorption of hematomas can allow the broken down blood cells and hemoglobin pigment to move in the connective tissue. For example, a patient who injures the base of his thumb might cause a hematoma, which will slowly move all through the finger within a week.

Its usage in UK dams was superseded about 1960 by the use of rolled clay in the core, and better control of moisture content. A considerable number of early notable dams were built in that era and they are now sometimes referred to as the 'Pennines embankment' type. These dams are characterized by a slender vertical puddle clay core supported on both sides by earthfill shoulders of more heterogeneous material. To control under-seepage through the natural foundation below the dam, the Pennines embankments generally constructed a puddle clay-filled cutoff trench in rock directly below the central core.

South Fork Dam failure and resulting flood that destroyed Johnstown in Pennsylvania in 1889 International special sign for works and installations containing dangerous forces Dam failures are generally catastrophic if the structure is breached or significantly damaged. Routine deformation monitoring and monitoring of seepage from drains in and around larger dams is useful to anticipate any problems and permit remedial action to be taken before structural failure occurs. Most dams incorporate mechanisms to permit the reservoir to be lowered or even drained in the event of such problems. Another solution can be rock grouting – pressure pumping portland cement slurry into weak fractured rock.

Only vestiges of these irrigation canals remain; however, the archeological area has not been completely explored. These irrigation canals are considered to be unique in Mesoamerica, not only because irrigation was not common in pre-Hispanic Mexico but because they are the only example of lined irrigation canals. It is not known why canal lining does not appear outside of the Hierve el Agua area, and here the lining develops naturally. While seepage and bank erosion were indeed problems with irrigation farming in other parts of Mesoamerica, the nearest example of anything similar is with the Hohokam of southern Arizona in 650 C.E.

Chungará is a lake situated in the extreme north of Chile at an elevation of , in the Altiplano of Arica y Parinacota Region in the Lauca National Park. It has a surface area of about and has a maximum depth of about . It receives inflow through the Río Chungara with some minor additional inflows, and loses most of its water to evaporation; seepage into the Laguna Quta Qutani plays a minor role. The lake formed between 17,000 and 8,000 years ago when the volcano Parinacota collapsed and the debris from the collapse dammed the Lauca River.

Water lilies in the Kortenhoefse Plassen The Kortenhoefse Plassen is a nature reserve in Wijdemeren that is managed by Natuurmonumenten. A mix of lakes, wetlands and strips of historical farmlands form a special nature area. Because these bodies of water are located near the higher ground of 't Gooi, the seepage of clean, nutrient-poor groundwater results in the growth of unusual plants such as marsh marigold. The water is filled with water lily in the summertime, and in the wintertime the shallow waters are one of the first to freeze over, making it a popular venue for ice skating.

The Wolf Creek Dam is a multi-purpose dam on the Cumberland River in the western part of Russell County, Kentucky, United States. The dam serves at once four distinct purposes: it generates hydroelectricity; it regulates and limits flooding; it releases stored water to permit year-round navigation on the lower Cumberland River; and it creates Lake Cumberland for recreation, which has become a popular tourist attraction. Because of seepage problems in the dam's foundation, it has become the U.S. Army Corps of Engineers's top dam priority. U.S. Route 127 is built on top of the dam.

An unusual feature of the river is the Inner Niger Delta, which forms where its gradient suddenly decreases. The result is a region of braided streams, marshes, and lakes the size of Belgium; the seasonal floods make the Delta extremely productive for both fishing and agriculture. The river loses nearly two-thirds of its potential flow in the Inner Delta between Ségou and Timbuktu to seepage and evaporation. All the water from the Bani River, which flows into the Delta at Mopti, does not compensate for the 'losses'. The average 'loss' is estimated at 31 km3/year, but varies considerably between years.

The heavy timber construction of the third floor provided structural support for not only that floor's cask, barrel and bottle aging space but also for the gravity-flow crushing area located on the floor above. The architects planned for the cellars to hold two million gallons of wine at a time, with thirteen tunnels in the hillside behind the building to hold another million gallons. Those tunnels collapsed due to effects of water seepage and of the 1906 San Francisco earthquake. A large number of men were hired for the building's construction, and local workers were chosen over non-locals.

The instructions were that the landfill should remain wet/moist to create a safe protective membrane. Following heavy rains during its dormancy, water had begun to pool in the landfill crater. The government pumped out this water which led directly to the drying and cracking of the landfill's permanent lining system meant to protect the landscape from waste seepage. The government spokesman tried to give some meaning behind the failed venture by saying the landfill will be opened after repairs even though some studies and experts claim landslides could take place in the area possibly dumping the waste downhill into the sea.

Boxcar Rapids near Maupin Much of the flow of the upper Deschutes River is diverted into canals to irrigate farmland; irrigation districts take nearly 98% of the river's flow in the summer months. The growth of cities like Bend and Redmond also increased demand on the river's water, which is over-allocated. Because the existing canals lose about half of their water due to seepage, there is pressure to convert these canals into pipelines, a move that is resisted by many locals for historic and aesthetic reasons. Golf courses have also been an issue with water allocation.

"Curving along the northern end of New Jersey's largest naturally formed lake, Budd Lake Bog supports a wetland habitat rare in New Jersey.... Budd Lake is considered the headwater source for the South Branch of the Raritan River." It is 7–12 feet deep, and can have large algal blooms. The bog, created by thousands of years of decaying plant material, supports wetland plants such as black spruce and tamarack, which grow on the floating mass. The lake is recharged through groundwater seepage through a series of wetlands, and serves as the headwaters of the Raritan River's South Branch.

All oil drilling into the South Ellwood Offshore field took place from Platform Holly, located about offshore The existence of an offshore field was suspected for a long time, largely due to the persistent natural seepage of oil from the sea floor. The Coal Oil Point seep field is now one of the most actively studied seep zones in the world. In 1966, ARCO built Platform Holly, in of water approximately southwest of Coal Oil Point, and began drilling wells into the various zones in the South Ellwood Offshore field. Peak production from the field was in 1984.

This species of salamander is commonly found in the lower Atlantic Coastal Plain of Georgia. It occurs on the Atlantic coastal plain from northeastern Florida to southeastern Virginia. The species is "unusually aquatic for a plethodontid," inhabiting "forested swamps fringing slow-moving blackwater streams, shallow ditches choked with aquatic vegetation, and mucky seepage areas." Stereochilus marginatus is also likely to be found under natural cover, such as Sphagnum moss or the decaying remains of leaves and other natural materials left behind in riverbeds; they can also sometimes be found underneath the remains of trees in drier environments.

Seepage of saltwater into the pits in which babai (Cyrtosperma merkusii or giant swamp taro) is grown is the major concern of islanders. The erosion problems are identified as being linked to aggregate mining, land reclamation and the construction of causeways that is thought to change the currents along the shoreline. The causeways have also resulted to reduced flushing of the lagoon that has resulted in low levels of oxygen in the lagoon, which has caused damage to fish stocks in the lagoon and causes other biological problems. Aggregate mining and the removal of coral boulders is exacerbating coastal erosion.

They found that the methane seeps originate not from the hydrates but from deep geological gas reservoirs (seepage from these formed the hydrates originally). They concluded that the hydrates acted as a dynamic seal regulating the methane emissions from the deep geological gas reservoirs and when they were dissociated 8,000 years ago, weakening the seal, this led to the higher methane release still observed today.Wallmann, K., Riedel, M., Hong, W.L., Patton, H., Hubbard, A., Pape, T., Hsu, C.W., Schmidt, C., Johnson, J.E., Torres, M.E. and Andreassen, K., 2018.

On the quarry floor, natural seepage has given rise to areas of open water, which grade into a variety of soligenous mire and fen vegetation types. Where a skeletal soil layer has developed on the quarry floor and spoil heaps, patches of grassland occur, with species characteristic of base-rich soils, such as quaking grass, Briza media, and limestone bedstraw, Galium sterneri. On shallow slopes, this gives way to a neutral grassland characterised by false oat-grass, Arrhenatherum elatius, and Yorkshire fog, Holcus lanatus. Above the quarry, this is replaced by acid grassland, in which wavy hair-grass, Deschampsia flexuosa, is dominant.

However, construction of the 7,804-meter tunnel proved to be extremely difficult due to numerous unforeseen problems with the local geology and contemporary tunneling technology. The Hakone mountain range is an active volcanic zone, containing a number of faults, and is subject to frequent earthquakes. In addition, workers encountered problems with a huge volume of water seepage, soft rock formations, and vents of hot spring water. On April 1, 1920, a large section of the tunnel from the Atami side collapsed, trapping 42 workers, 17 of whom were rescued a week later after heroic efforts to dig them out.

Navy diver George D Stillson found the superstructure caved in and the hull filled with water. One of the divers involved in the salvage operation was John Henry Turpin, who was, probably, the first African-American to qualify as a U.S. Navy Master Diver. Only four of the dead could be identified; the 17 others were buried in Arlington National Cemetery. The investigating board subsequently conjectured that corrosion of the lead lining of the battery tank had permitted seepage of sea water into the battery compartment and thereby caused the commanding officer to lose control on a submerged run.

This station opened just after midnight on November 23, 1904, as part of the IRT's original system. It was completed along with the rest of the IRT Lenox Avenue Line, then known as the East Side Subway or East Side Branch, south of 145th Street. Starting on March 2, 1998, the tunnel was reconstructed along with the cracked tunnel floor. This was done to correct a major water problem that had existed for many years due to the presence of the Harlem Creek and other underground streams, which caused extensive flooding, water damage, and seepage problems that occasionally contributed to severe service disruptions.

The most fascinating feature of the Caves of Castellana are the concretions. This term is used to indicate the mineral deposits that covered the naked walls of a cave by crystallisation of the calcite carried in solution by infiltrating rain water, that had penetrated all the overhanging layers of the rock by a very slow seepage. When the water drips through the roof of an empty cavern, the calcite dissolved in it deposits on the roof and going downwards takes the shape of a stalactite. When the drop of water falls on the floor, the calcite takes the shape of a stalagmite.

Different hygiene products such as tampons, menstrual cups, and sanitary napkins are available to absorb or capture menstrual blood. The Bartholin's glands, located near the vaginal opening, were originally considered the primary source for vaginal lubrication, but further examination showed that they provide only a few drops of mucus. Vaginal lubrication is mostly provided by plasma seepage known as transudate from the vaginal walls. This initially forms as sweat-like droplets, and is caused by increased fluid pressure in the tissue of the vagina (vasocongestion), resulting in the release of plasma as transudate from the capillaries through the vaginal epithelium.

Adult empidids are found in a variety of forest habitats, on the leaves of plants, on tree trunks, aquatic vegetation and also in stream beds and seepage habitats. Some species are associated with open areas such as grasslands, agricultural fields, marshes, coastal zones and beaches. Adults capture arthropod prey, including other Diptera (including other empidids), Hemiptera, Homoptera, Lepidoptera, Trichoptera, Thysanoptera, Hymenoptera, Neuroptera, Plecoptera, Ephemeroptera, Coleoptera, Collembola, and Acari. Because of their predation they are important natural and biological control agents of various pest insect species and as a group with a vast species diversity they occupy a wide range of habitats.

The dumping ground was immediately closed following the incident by then-President Joseph Estrada but was reopened weeks later by then-Quezon City Mayor Ismael Mathay Jr. to avert an epidemic in the city due to uncollected garbage caused by the closure. In 2004, the landfill was reorganized as a controlled disposal facility but was closed in December 2010. A separate landfill with stricter waste management policy was established nearby the old open dumpsite in January 2011. Garbage in the dumpsite was dumped on a layer of tarpaulin to prevent seepage of leachate to the groundwater.

Precipitation of authigenic carbonates and other geologic events will undoubtedly alter surface seepage patterns over periods of many years, although through direct observation, no changes in chemosynthetic fauna distribution or composition were observed at seven separate study sites (MacDonald et al., 1995). A slightly longer period (19 years) can be referenced in the case of Bush Hill, the first Central Gulf of Mexico community described in situ in 1986. No mass die-offs or large-scale shifts in faunal composition have been observed (with the exception of collections for scientific purposes) over the 19-year history of research at this site.

The lake is located in a broad valley named Rush Valley near the town of Stockton and several miles south of Tooele, and is fed by snowmelt from six mountain ranges. These are the Sheeprock Mountains in the south, the East Tintic Mountains to the southeast, the Oquirrh Mountains to the east, South Mountain to the north, the Stansbury Mountains to the northwest and west, and the Onaqui Mountains to the southwest. The runoff from these mountain regions create only intermittent surface flow to the lake, but does reach it via groundwater seepage. The highest point in the watershed is Lowe Peak, at .

Howard A. Hanson Dam is an earthen embankment dam on the Green River, 21 miles (34 km) east of Auburn, Washington. The dam was completed in 1961 and its primary purpose is flood control along with water supply for Tacoma, Washington. After the dam's reservoir reached record levels in January 2009, the U.S. Army Corps of Engineers discovered seepage in the right abutment of the dam, leading to efforts to mitigate a potential flood. Improved drainage works were completed in October 2011 and although studies are still underway, the dam was declared safe to maintain its maximum reservoir level.

According to the Water Quality Index, 96% of Mexico's surface water bodies have different levels of pollution. OECD estimates the economic cost of water pollution in Mexico at US$6 billion per year. The problem is most serious in the Valle de Mexico region where 100% of the water bodies have different levels of contamination, 18% of which are highly polluted. Low water quality is due to untreated discharge of industrial effluents and municipal wastewater into rivers and lakes, solid waste deposits along river banks, uncontrolled seepage from unsanitary landfills, and non- point pollution mainly from agricultural production.

Hypericum erythreae, the Georgia St. John's-wort, sparse-leaved St. John's-wort, or grit St. Johnswort, is a species of flowering plant in the St. John's wort family, Hypericaceae. It is native to the southeastern United States in seepage bogs and roadside ditches. Its name grit St. Johnswort comes from its limited distribution, within the Altamaha Grit region of the Georgia coastal plain. According to "Hypericum Online", it is found from Maryland to southern Illinois, south to Florida and Louisiana, though this may be in error, as many other sources list it as occurring only in Georgia and South Carolina.

Seepage of methane upwards along conduits, such as faults and old well boreholes, caused an explosion at a Ross Dress for Less store in 1985 on 3rd Street in the Fairfax District which injured 23 people. The Ross Dress for Less store still stands in the 6200 block of 3rd Street, on the southeast corner of Fairfax Ave. and 3rd. Overnight on March 24, 1985, methane gas filled an auxiliary room at the store and ignited, causing a spectacular explosion which blew out the windows and tore the roof off of the building, injuring 23 people, and reducing the inside to rubble.

Waste from these farms have the potential to carry pathogens, bacteria (often antibiotic resistant), and heavy metals that can be toxic when ingested. Pig waste also contributes to groundwater pollution in the forms of groundwater seepage and waste spray, which is essentially the usage of a sprinkler to spray vats of pig waste into neighboring areas. The contents in the spray and waste drift have been shown to cause mucosal irritation, respiratory ailment, increased stress, decreased quality of life, and higher blood pressure. This improper way to get rid of waste is an attempt for CAFOs to be cost efficient.

Even if the bombs only hit a small part of the roof, damages quickly extended across the whole structure because of a colossal fire that was not noted and quenched in time, testament to Milan's general state of disarray on that eventful night. All wooden fixtures and furnishings went lost but the high temperature damaged even the famous stuccoes and Appiani's paintings, ruining the Hall of Caryatids beyond repair. Its wooden beams collapsed and trusses smashed on the floor, damaging it together with the vault, the balcony and the gallery. The other halls were also damaged by water seepage, after many of the roof tiles went lost in the raid.

There are large quantities of dissolved iron and aluminum in the waters of Mahanoy Creek. Additionally, there are trace amounts of various metals, including cobalt, nickel, copper, zinc, and lead, sulfates, manganese, and beryllium. There are traces of numerous other metals in the waters, but their concentrations conform to drinking water standards. Out of the 35 or more acid mine drainage sources in the Mahanoy Creek watershed, the four most significant ones are the Locust Gap Tunnel, the Packer #5 Breach, the Packer #5 Borehole, and the Girard Mine seepage. The 15 most significant sources have discharges of between 29,200 liters per minute and 680 liters per minute.

The Munisport Landfill is located about from Biscayne Bay. Natural soils in the landfill area had been removed prior to dumping, increasing risk of pollution seepage, especially into the Biscayne Aquifer, a primary source for drinking water in South Florida. The solid waste was disposed of without the use of a liner and with no leachate control mechanisms, so rainfall percolating through the solid waste has caused the release of elevated levels of ammonia and other contaminants into the underlying groundwater and discharges into adjacent surface water. The remainder of Munisport site beyond the landfill area unfortunately lies below the mean high water line, further increasing risk.

The case involves the Apalachicola-Chattahoochee- Flint (ACF) River Basin, which includes three major rivers in the southeast United States. The Chattahoochee River runs from the southern end of the Appalachian Mountains in northern Georgia and runs south-southwest and towards the Gulf of Mexico; it forms the state border between Georgia and Alabama. The Flint River forms from groundwater seepage in northern Georgia, and also runs south-southwest until it meets with the Chattahoochee at the southern edge of both Georgia and Alabama. The combined rivers become the Apalachicola River which then crosses Florida's panhandle and empties into Apalachicola Bay, an estuary abutting the Gulf.

The cooling system was made by Delphi Automotive, a former Harrison Radiator Division of General Motors. This was a bold step for Apple, and should have allowed the use of very fast processors, giving Apple an advantage in both the performance and reliability race, but the system turned out to be subject to coolant leakage. If not caught in time, the leakage could destroy the processors, logic board, and even corrode the aluminium casing itself. While leakage was sometimes detectable by drops of green coolant in or beneath the machine, in many machines the seepage is so slight that it was almost impossible to detect without dismantling the entire computer.

Officially, decommissioning an oil rig is the act of removal according to regulatory requirements and includes flushing, plugging and cementing wells to make them safe. Decommissioning is complicated by factors such as cost, safety, operational duration, environmental issues, risk, experience, and historical relationship between operator and state. As part of decommissioning, the operator must deal with the shell mound that collects on the bottom surrounding the rig. The mound forms on the pile of cuttings discharged from the original drilling operations, shells that have fallen from the platform's underwater structure, and material that has fallen and/or leaked from the platform, occasionally mixed with well seepage.

Antonio was also conscious of adapting his buildings to the tropical climate of the Philippines. In order to highlight natural light and also avoid rain seepage, he utilized sunscreens, slanted windows and other devices. Antonio himself has been quoted as stating that "buildings should be planned with austerity in mind and its stability forever as the aim of true architecture, that buildings must be progressive, simple in design but dignified, true to a purpose without resorting to an applied set of aesthetics and should eternally recreate truth" . When he was named National Artist of the Philippines in 1976, he was only the second architect so honored, after his contemporary, Juan Nakpil.

In the 21st-century modernisation of the Great Western Main Line, the tunnel was prepared for electrification. The tunnel had good clearances and was relatively easy to electrify but the continuous seepage of water through its roof in some areas provided a challenge. The options of using conventional tunnel electrification equipment or a covered solid beam technology were considered and it was decided to use the solid beam approach. An aluminium conductor rail held in place using 7000 high-grade stainless steel fixtures, resistant to the hostile environment in the tunnel, was installed to hold an un-tensioned copper contact cable along the length of its roof.

The watershed of the lake covers an area of about . Springs, four of which are permanent, are the main source of its water which flows for some distance before reaching the lake surface; diffuse seepage of water within the wetlands and the lake itself makes up the rest of the water supply. Part of the water comes from Tuyajto volcano as well as Pampa Las Tecas and Pampa Colorada east and northeast from Tuyajto Lake and flows underground towards Tuyajto. In general, groundwater in the region is salty to brackish, it originates as rain or snow and probably obtains salts from underground salt bodies.

Experimental Dam wall, showing raised area of wall, from W, 2003 The dam is constructed as a curved stone overshot weir, with later form-cast concrete additions above, at the entrance to a narrow gully of Kennedy Creek at the southern end of the Mount Isa Mine tailings and seepage ponds (). The wall shows the height of original construction and of two subsequent extensions in height and width. The original section is of rendered stone, initially rising an estimated above the original valley floor, assuming a current build-up of about of silt. The deep overflow was subsequently in-filled with roughly rendered stonework.

The embankment section of the dam has experienced seepage problems at several points in its lifetime, the first during the 1980s, which was corrected in 1996 with the construction of a drainage system. The leak re-emerged in 2009 and 2010, when it was discovered that water was leaking between the dam structure and the original ground surface, requiring extensive re-construction and filling work. In 2005 USGen New England filed for bankruptcy, and TransCanada purchased Moore Dam and 13 other hydroelectric stations for the sum of $505 million. As of 2016, TransCanada intends to sell the dam to local utilities in Vermont and New Hampshire.

Since then, the NAS building had undergone an 18-month revamp in 2017, the first time since it moved there in 1997. The revamp would fix wear and tear, including water-seepage and paint peeling, as well as enhance the look of the building with restorations to reflect the building's past. These changes will allow the building to blend with its surroundings. The building reopened on 7 April 2019 with better facilities, with an expanded Oldham Theatre taking 132 people instead of 44 before, three new oral history recording studios, microfilm readers and expanded conservation labs, as well as lifts installed and levelled floors for the disabled.

John Shearman, essay The Chapel of Sixtus IV in The Sistine Chapel, ed. Massimo Giacometti, (1986) Harmony Books, Continued ingress of water from the roof and from unroofed exterior walkways above the ceiling level had caused seepage which carried down salts from the building mortar and deposited them on the ceiling through evaporation. In places, this caused the surface of the frescoes to bubble and lift. Although discolouration was a serious problem, bubbling was not, because the thinness and transparency of the paint which Michelangelo employed on the greater part of the ceiling permitted the salts to pass through rather than accumulating beneath the surface.

Subirrigation also known as seepage irrigation, is a method of irrigation where water is delivered to the plant root zone. The excess may be collected for reuse. Subirrigation is used in growing field crops such as tomatoes, peppers, and sugar cane in areas with high water tables such as Florida and in commercial greenhouse operations. Three basic types of subirrigation system are in general use for potted plants in greenhouses: ebb-and-flow (bench- mounted enclosures holding pots are filled and then drained); trough (water is flowed through bench-mounted, slightly sloping enclosures containing pots); and flooded floor (special sloped concrete flooring is flooded and drained).

The north of the island is dominated by a well developed, thick, thrift (Armeria maritima) turf whilst the southern part is dominated by dense stands of bracken (Pteridium aquilinum), bramble (Rubus fruticosus) and bluebells (Hyacinthoides non-scripta), with some sand sedge (Carex arenaria) and Yorkshire fog (Holcus lanatus). Thickets of tree mallow (Lavatera arborea) have developed at the back of some of the boulder beaches. There were scattered colonies of shore dock (Rumex rupestris) until a storm in 1982 swept away some of the boulder beaches. One colony remains in the corner of a relatively sheltered beach in the south of the island at a freshwater seepage.

The ground water seepage has produced the lake which many locals know as "Blue Lake". Following on from residential development in Bundoora, subdivisions occurred in the 1970s and a kindergarten, pre-school centre and shopping complex were built by the end of the decade. The shopping centre has several historic place names: The "Stables Shopping Centre" and Redleap Avenue commemorate the solidly built Redleap racing stables on the Miller property and the Plough Hotel commemorates the Plough Inn which formed a nucleus village in the Mill Park area during the 1850s. The street "Mill Park Drive" is a large oval ring, which was once a horse racing track.

Canadian Geotechnical Journal, 26, 484-490. and thus the seismic events were more likely caused by the impact of the landslide masses on the opposite valley wall. Changes in groundwater condition, often a trigger for landslides, is not thought to have played a role in the Hope Slide as the slide occurred during a protracted period of sub-zero temperatures in the winter, though some have suggested that freezing of seepage exit points may have caused an increase in water pressure at the toe of the slide.

The outcome of this confrontation is not clearly documented. In 1854, rainfall was less than two thirds of the normal average, and the reservoirs ran dry. Consideration was given to providing other sources of water, and £595 was spent on constructing a small reservoir on Mapperley Brook, and on raising the banks of the old reservoirs at Shipley and Mapperley. Further problems arose from seepage, which resulted in a puddle bank being constructed at the head of the canal between 1857 and 1866, and extensive puddling being carried out at Limekiln lock in 1866, which had little effect, since canal water was reputedly entering two mines there in 1867.

During World War I, he was a quartermaster in the British Army. In his efforts to source food and supplies for the British Army in Mesopotamia (today's Iraq), Holmes travelled widely through the Middle East and may have heard rumours of a possible oil seepage on the eastern seaboard of the Arabian peninsula. This, together with a close study of Admiralty maps of the area, appears to have triggered an abiding interest in oil in the region. By 1918, he was writing to his wife that "I personally believe that there will be developed an immense oil field running from Kuwait right down the mainland coast [of eastern Arabia]".

An externality exists when a person makes a choice that affects other people in a way that is not accounted for in the market price. An externality can be positive or negative but is usually associated with negative externalities in environmental economics. For instance, water seepage in residential buildings occurring in upper floors affect the lower floors.Rita Yi Man Li (2012), The Internalisation Of Environmental Externalities Affecting Dwellings: A Review Of Court Cases In Hong Kong, Economic Affairs, Volume 32, Issue 2, pages 81–87 Another example concerns how the sale of Amazon timber disregards the amount of carbon dioxide released in the cutting.

False Bay has a high incidence of dinoflagellate blooms that may produce toxins or accumulate as red tides. The water retention and stratification of late summer and autumn produce the environment most conducive to harmful algal blooms. Algal blooms tend to propagate clockwise with the circulation, and may become trapped in the Gordon's Bay eddy for more extended periods. Brown discoloration in the surf zone along the north shore is frequently due to persistent blooms of the non-toxic diatom Anaulus australis, which is provided with nutrients from groundwater seepage through the sand bottom and river outfalls containing waste water from the nearby sewage purification systems.

Historically, Native Americans made extensive use of the lands surrounding Lake Wingra, which takes its name from the word for "duck" in the language of the Ho-Chunk Nation.Wingra Water Trail Map In the past, Lake Wingra was a very productive lake ecosystem with significant groundwater inputs. These inputs primarily took the form of surface springs and subsurface seepage, with drainage running through Wingra Creek to Lake Monona and the Yahara River, which is part of the Upper Rock River drainage, a tributary to the Mississippi River. Over the past two hundred years, human use of the lake and its watershed have changed significantly.

Nearly all of the water entering Lake Ellesmere / Te Waihora is derived from the groundwater system that underlies the gravel-dominated strata of the Central Canterbury Plains. The groundwater system is fed from two sources of recharge: rainfall incident on the plains and subterranean seepage from the Rakaia and Waimakariri Rivers. The exception to this is periods of persistent rainfall, usually during winter when discharge into Lake Ellesmere / Te Waihora is supplemented by surface flow derived from the foothills from the Rakaia Gorge to Darfield. This illustrates why Lake Ellesmere / Te Waihora has undergone significant ecological transformation in recent years as land use practices in the catchment area have changed.

The walls are about twelve inches thick and consist of two layers with a space the width of a brick between them to provide insulation. Foundation walls are even thicker to prevent seepage of water into the basement when flood irrigation was taking place around the house. The house had many conveniences not enjoyed by other homes in the community. It was lit by electricity, powered by twelve batteries, which were recharged by a motor, it was centrally heated by radiators and a coal-fired furnace, and had hot and cold running water which was pumped from a very large cistern beside the house into a storage tank in the basement.

One of the first cold local heating networks uses seepage water from the Furka Base Tunnel as a heat source The first cold district heating network is the heating network in Arzberg in Upper Franconia, Germany. In the Arzberg power station there, which has since been shut down, uncooled cooling water was taken from between the turbine condenser and the cooling tower and piped to various buildings, where it was then used as a heat source for heat pumps. This was used to heat the school and the swimming pool in addition to various residential buildings and commercial enterprises.Leonhard Müller: Handbuch der Elektrizitätswirtschaft: Technische, wirtschaftliche und rechtliche Grundlagen.

On this major axis, the "backbone" of the project, has created spaces for encounter and relaxation. The latest techniques have been implemented for the economic management of energy, giving maximum comfort to staff and the public while ensuring the development of architectural building. Opened in May 2007, by January 2011 all buildings already had developed many problems of water seepage and stability. Thus one of the gateways weighing a hundred kilos came off its hinges and nearly fell on a lawyer who entered, cracks opened between concrete blocks, the joints of windows let in wind and water when it rains in the concourse, etc.

While flowing from the sluices, coarse material is deposited first and then finer material is deposited (fine material has a slower terminal velocity thus takes longer to settle, see Stoke's Law) as the flow velocity is reduced towards the center of the dam. This fine material forms an impervious core to the dam. The water flow must be well controlled at all times, otherwise the central section may be bridged by tongues of coarse material which would facilitate seepage through the dam later. Hydraulic fill dams can be dangerous in areas of seismic activity due to the high susceptibility of the uncompacted, cohesion- less soils in them to liquefaction.

Bull Run Reservoir 1 lies behind a concrete arch-gravity dam built in 1929. Although most of the watershed is generally closed to the public, the protected area includes forest roads, buildings, three dams and reservoirs, two hydroelectric power stations, and other infrastructure used by government employees who manage the forest and the water supply system. The system includes a concrete dam and spillway, added to the natural outlet of Bull Run Lake. The dam, completed in about 1960, was preceded in 1915 by a timber-and-rockfill structure and later by other measures to increase the lake's storage capacity and to prevent seepage.

About 60 percent of the reefs occur next to or inside seabed pockmarks. Because these craters are formed by the expulsion of liquids and gases (including methane), several scientists hypothesize that there may be a link between the existence of the deep-water coral reefs and nutrients seepage (light hydrocarbons, such as methane, ethane, and propane) through the seafloor. This hypothesis is called the 'hydraulic theory' for deep-water coral reefs. Hovland and Risk, 2003 Lophelia communities support diverse marine life, such as sponges, polychaete worms, mollusks, crustaceans, brittle stars, starfish, sea urchins, bryozoans, sea spiders, fish and many other vertebrate and invertebrate species.

This bill transfers, for a limited time, the proceeds of the Lake Belt water treatment upgrade fee from Miami-Dade County to the South Florida Water Management District to pay for seepage mitigation projects. Senator García and then-incoming Senate President Don Gaetz passed CS/CS/CS SB 1568. This bill set up new requirements as to the steps needed to take when a public hospital is going to be sold or leased. Some of the new requirements included requiring any sale or lease of a public hospital that is owned by a county, district, or municipality to be approved by the Chief Financial Officer (CFO) of Florida.

Secondhand smoke is a major cause of disease and premature death, including lung cancer, heart disease, and respiratory problems in nonsmoking adults. According to the U.S. Surgeon General, there is no safe level of secondhand smoke exposure. Children exposed to secondhand smoke are at increased risk of Sudden Infant Death Syndrome (SIDS) and are more susceptible to respiratory infections, asthma, and ear infections. One study showed that children who live in homes in which no one smokes inside have a 45% increase in cotinine levels if they live in multi-unit housing compared with detached homes, due to seepage through walls and shared ventilation systems.

This map shows the United State Geological Survey's compartmentalized map of Water Conservation Areas 1, 2 and 3 Water Conservation Area 3 (WCA-3) is the largest existing WCA covering a total of 915 square miles within Western Dade and Broward Counties. Lying southwest of WCA-2 and just north of Everglades National Park, WCA-3 is used primarily as an area to receive flood waters from adjacent areas and store them for beneficial municipal, urban, and agricultural uses. It was subdivided into WCA-2A and WCA-2B by way of the L-67 canal and levees as a safeguard against seepage into the aquifer.

Workers were ordered to seal off the leak, but they were not entirely successful and water continued to permeate through the face of the dam. A two- inch pipe was used to collect this seepage and was laid from the fault line down to the home of the dam keeper, Tony Harnischfeger, which he used for domestic purposes. Water that collected in the drainage pipes under the dam to relieve the hydrostatic uplift pressure was carried off in this manner as well. In April 1927 the reservoir level was brought to within ten feet of the spillway, and during most of May the water level was within three feet of overflowing.

As it does, it displaces warmer, more buoyant air which naturally rises and exits the mouth of Booming Ice Chasm. As the warmer air escapes into the atmosphere, it is replaced by a new current of cold air that enters the cave in small circular flows creating an air flow system similar to swirling eddies in a stream, known as eddy currents. As a result, Booming Ice Chasm is insulated from external warm air, maintaining temperatures within Booming Ice Chasm to less than freezing all year around. Secondly, the ice itself is slowly expanded by the cumulative action of low levels of precipitation, seepage and drip water throughout the year.

Dense seagrass beds still exist in King George Sound, although they have been adversely affected by increased nutrient levels and industry in the area. Some of the seagrasses present in the sound include Posidonia australis, Posidonia robertsoneae, Posidonia kirkmanii, Posidonia sinuosa, Posidonia denhartogii, Posidonia ostenfeldii, Amphibolis antarctica, Amphibolis griffithii, Halophila australis, Halophila ovalis, Ruppia megacarpa and Heterozostera tasmanica. The fringing vegetation around the sound includes both the saltmarshes of Oyster Harbour and Princess Royal Harbour, and the sandy beach vegetation. Saltmarshes contain a variety of species including samphire, seablite, astartea, wattle, greenbush, shore rush, twig rush and saltwater paperbark Freshwater species also occur in areas where substantial freshwater seepage occurs.

Development in Austin in the 1970s and 1980s began to threaten both the creek's water quality and wildlife. Heavy rainfall often led to contamination of the stream due to runoff and sewer line seepage from the upstream subdivisions entering the Edwards Aquifer recharge zone. Following public outcry, the Austin City Council passed the Barton Creek watershed ordinance in 1980 and the Comprehensive Watersheds Ordinance in 1986. Proposals in 1990 to develop land in the watershed resulted in more public outcry, which spurred passage of the Save Our Springs Citizens' Initiative of 1992, which severely limited construction, curtailed tax exemptions, established pollution control standards and implemented methods for reducing accidental contamination.

London Clay is an ideal medium for driving tunnels, which is why the London Underground railway network expanded quickly north of the River Thames, but south of the Thames the stratum at tube level is water-bearing sand and gravel (not good for tunnelling) with London Clay below, which is why there are few tube tunnels there. London Clay has a stand-up time long enough to enable support to be installed without urgency. It is also almost waterproof, resulting in virtually no seepage of groundwater into the tunnel. It is over-consolidated, which means that it is under pressure, and expands upon excavation, thus gradually loading the support, i.e.

Chemosynthetic communities in the northern part of Gulf of Mexico around cold seeps known in 2000 There is a clear relationship between known hydrocarbon discoveries at great depth in the Gulf slope and chemosynthetic communities, hydrocarbon seepage, and authigenic minerals including carbonates at the seafloor (Sassen et al., 1993a and b). While the hydrocarbon reservoirs are broad areas several kilometers beneath the Gulf, chemosynthetic communities occur in isolated areas with thin veneers of sediment only a few meters thick. The northern Gulf of Mexico slope includes a stratigraphic section more than 10 km (6 mi) thick and has been profoundly influenced by salt movement.

By December, seven of the actual piles had been pulled from the ground and measured. The Engineering News Record reported on December 16 that they ranged from 23' 3 1/8" to 23' 7 7/16" long, well within the original design specifications, contradicting the early report of short pilings. They also found that homeowners along the 17th Street Canal, near the site of the breach, had been reporting their front yards flooding from persistent seepage from the canal for a year prior to Hurricane Katrina to the Sewerage and Water Board of New Orleans. However, no data exists confirming that the water was coming from the canal.

One worker was killed and four were injured in a partial collapse on November 25, 2019 in the 14 story luxury apartment at 4th & Race under construction in Cincinnati that is being built by Turner for Cincinnati Center City Development Corporation (3CDC) and Flaherty & Collins. Cement was being poured onto seventh floor which was being supported from below on a temporary structure called "shoring" placed on the sixth floor. Workers were inspecting for cement seepage from sixth floor when the floor above collapsed from the weight of cement. A worker has gone missing in the collapse who was found dead more than a day later in the rubble.

Two oedometers at the University of Cambridge Soil consolidation refers to the mechanical process by which soil changes volume gradually in response to a change in pressure. This happens because soil is a two-phase material, comprising soil grains and pore fluid, usually groundwater. When soil saturated with water is subjected to an increase in pressure, the high volumetric stiffness of water compared to the soil matrix means that the water initially absorbs all the change in pressure without changing volume, creating excess pore water pressure. As water diffuses away from regions of high pressure due to seepage, the soil matrix gradually takes up the pressure change and shrinks in volume.

The powerhouse was doubled in size, and provisions for four more turbines were made. Turbines 5 and 6 were commissioned four years later in 1938. The last two turbines were commissioned in 1946 to meet the increasing demand for electricity following World War II. In 1990, a $50 million repair, refurbishment and upgrade project was completed, the first stage of which involved construction of a diversion channel. In 2000 it was determined that the historic seepage problem had worsened, interim repairs were carried out while a more permanent solution was devised and this took the form of a $20 million engineering project, which was carried out in 2005–07.

Example applications are building and bridge foundations, retaining walls, dams, and buried pipeline systems. Principles of soil mechanics are also used in related disciplines such as geophysical engineering, coastal engineering, agricultural engineering, hydrology and soil physics. This article describes the genesis and composition of soil, the distinction between pore water pressure and inter-granular effective stress, capillary action of fluids in the soil pore spaces, soil classification, seepage and permeability, time dependent change of volume due to squeezing water out of tiny pore spaces, also known as consolidation, shear strength and stiffness of soils. The shear strength of soils is primarily derived from friction between the particles and interlocking, which are very sensitive to the effective stress.

On August 27, 1859, Edwin Drake dug a successful commercial oil well in Titusville, Pennsylvania which is commonly credited as the first oil well dug specifically as a commercial well in the United States. Days after the Drake well came in, news reached the Grandin General Store in Tidioute approximately 20 miles away. After hearing that Drake was selling barrels of oil at 75 cents each, John Livingston (then aged 23) who knew of petroleum seepage in the area, immediately began buying up small tracts of land surrounding an “oil spring” he knew of. On August 31, 1859, 4 days after the Drake well, John Livingston set up a spring-pole well, a simpler setup than Drake's technique.

The seep field is among the largest and best studied areas of active marine seepage in the world. These perennial and continuous oil and gas seeps have been active on the northern edge of the Santa Barbara Channel for at least 500,000 years. The combined seeps in the field release about 40 tons of methane per day and about 19 tons of reactive organic gas (ethane, propane, butane and higher hydrocarbons); about twice the hydrocarbon air pollution released by all the cars and trucks in Santa Barbara County in 1990.J.

Scott Hornafius and Bruce Luyendyk, along with graduate student Derek Quigley made sonar surveys of the COP field two decades later using 50 kHz sonar and 3.5 kHz sonar equipment that matched that used by Fischer and colleagues. They calibrated the sonar data with seafloor artificial sources to estimate the volume of gas discharge cited above. Using an estimate of the gas/oil ratio along with capture of oil with a floating boom, they also estimated the volume of oil discharge (above). Comparing the surveys made in the mid 1990s with the early 1970s data of Fischer and colleagues they determined that seepage near the producing platform Holly had decreased by half.

Rodgers' background in the blackface minstrel shows and as a railroad worker enabled him to develop a unique musical hybridization drawing from both black and white traditions, as exemplified by the blue yodel songs. In his recordings Rodgers and his producer, Ralph Peer, achieved a "vernacular combination of blues, jazz, and traditional folk" to produce a style of music then called 'hillbilly'. ‘Black and White Cultural Seepage in Country’, by Cole M. Greif-Neill, "Your folyops" website (2005). Rodgers' blue yodel songs, as well as a number of his other songs of a similar pattern, drew heavily on fragmentary and ephemeral song phrases from blues and folk traditions (called "floating lyrics" or "maverick phrases").

Developers and farmers intertwining interventions: the case of rainwater harvesting and food-for-work in Degua Temben, Tigray, Ethiopia Giba dam building site in 2019 A major change is the construction of Lake Giba, a 350 million m³ reservoir on the Giba river that will occupy the whole lower eastern side of the tabia. The reservoir is mainly intended to provide water to Mekelle. The lithology of the dam building site is Antalo Limestone. Part of its water is anticipated to be lost through seepage; the positive side- effect is that this will contribute to groundwater recharge and river baseflow in the downstream areas, which largely belong to tabias Addi Azmera and Debre Nazret.

These mites are typically abundant along the margins of temporary ponds, springs, streams, and seepage areas in North America and Europe. Nymphs and adults can be seen crawling and mating along substrate beginning in early Spring, soon after the recession of surface ice. Eggs are laid soon after the thaw, and larvae typically emerge and begin host seeking within 30–40 days. According to Mullen (1977), P. barbigera attach exclusively to female mosquitoes as they land near the water's edge to oviposit, which was supported by an extensive field study in which he observed zero mite larvae on 15,000 Aedes pupae, and dissection of parasitized females revealed them all to be parous.

The method uses seasonal water balance components as input data. These are related to the surface hydrology (like rainfall, evaporation, irrigation, use of drain and well water for irrigation, runoff), and the aquifer hydrology (like upward seepage, natural drainage, pumping from wells). The other water balance components (like downward percolation, upward capillary rise, subsurface drainage) are given as output. The quantity of drainage water, as an output, is determined by two drainage intensity factors for drainage above and below drain level respectively (to be given with the input data), a drainage reduction factor (to simulate a limited operation of the drainage system), and the height of the water table, resulting from the computed water balance.

San Andreas Creek's source elevation is at approximately on the eastern slopes of Sweeney Ridge from which it flows southeasterly along the San Andreas Rift between Sweeney Ridge to the west and Buri Buri Ridge to the east, through San Andreas Reservoir, which was formed by the construction of a earth dam in 1868. The San Andreas Dam eliminates flow in the creek immediately below the dams, except for occasional spills or releases from the reservoir and seepage through the dam. From San Andreas Reservoir, the creek descends and enters the northeast arm of Lower Crystal Springs Reservoir. Historically San Andreas Creek joined San Mateo Creek just above the current location of the Crystal Springs Dam.

Further explorations in the area yielded nothing useful with a majority of the nearby drilling sites abandoned by 1908, but general exploration in more northerly portions of Alberta yielded the Turner Valley field in 1914. The Oil Creek strike is believed to be the result of oil seepage along fault planes in the Lewis Overthrust, in which oil originating in younger Cretaceous rock has moved upwards through older Pre- Cambrian rock that has been forced over the oil-bearing layers. More oil in the Waterton area was eventually discovered at the Pincher Creek oil field in 1948. A small monument, depicting a stylized drill rig, was placed over the well in 1968.

Below the outer hills is a dry boulder-strewn tract, corresponding to the Bhabar of Kumaun and Garhwal and here the bulk of the moisture contributed by the rainfall and the small streams is absorbed by the soil, to reappear through seepage in the damp and unhealthy tract, known as the terai. The climate is extreme temperate climate, with soaring temperatures in summer crossing 40 degrees and in winters temperatures as low as 3 to 4 degrees. There are a number of cinemas and malls and supermarkets in Kanhaiya Takij, Krishna Takij, Sahu Palace, Padrauna such as Unik Bazar, V2, Super Market, City Cart, and V Mart. A city mall has also been proposed.

Also recorded as Anete in 1305, Anet in 1339, Agnet in 1570 and Agnet iland alias Annett in 1650. In the 19th century Annet was ″used for pasturage by the inhabitants of other islands″ although with only one freshwater seepage there could not have been many animals grazing on the island. The SS Castleford struck the Crebawethans in June 1877 and led to some of her cargo of 250 to 450 cattle being landed on the island and staying there for up to 10 days. Gurney (1889) reported that "... the animals trampled everything and would have caused an immense amount of damage at the peak of the shearwater and storm petrel nesting season".

The namesake of the natural area, Dorothy Lake, is a 5.2 acre soft-water seepage lake, and contains a large, diverse assemblage of invertebrates, as well as three rare plant species. Three smaller, unnamed lakes surround Dorothy Lake, one of which contains a high- quality floating poor fen border. The uplands surrounding the lakes and wetlands contain northern mesic and dry-mesic forests, of primarily white pine (Pinus strobus), red pine (Pinus resinosa), and red oak (Quercus rubra). Rare plant species that can be found on the site include Blunt-Lobe Grape Fern (Botrychium oneidense), Prickly Hornwort (Ceratophyllum echinatum), White Adder's Mouth (Malaxis monophyllos), Farwell's Water Milfoil (Myriophyllum farwellii), Bog Bluegrass (Poa paludigena), and Hidden-Fruited Bladderwort (Utricularia geminiscapa).

Lycian Tomb of Telmessus Telmessos was a flourishing city in the west of Lycia, on the Gulf of Fethiye. It was famed for its school of diviners, consulted among others by the Lydian king Croesus, prior to declaring war against Cyrus, and by Alexander the Great, when he came to the town after the siege of Halicarnassus. The sign on site says one statue has been destroyed by water seepage and two others damaged. August 2011 Telmessos was a member of the Delian League in the 5th century BC. It was taken by Alexander in 334 BC. Telmessos was renamed Anastasiopolis in the 8th century AD, apparently in honour of Emperor Anastasios II, but this name did not persist.

In the United States, many of the first commercial fields in California were found using this method including the Newhall Field discovered in 1876 and the Kern River Field discovered in 18997. Seeps have also been used to find offshore fields including the Cantarell Field in Mexico in 1976; the largest oil field in Mexico and one of the largest in the world. The field is named after a fisherman, Rudesindo Cantarell, who complained to PEMEX about his fishing nets being stained by oil seeps in the Bay of Campeche. The biological and geochemical manifestations of seepage leads to distinct bathymetrical features including positive relief mounds, pinnacles, mud volcanoes and negative relief pockmarks.

In May 2009, the U.S. Army Corps of Engineers (USACE) inspected the Gathright Dam as part of Screening Portfolio Risk Analysis and routine inspections. Later in the year on September 2, the USACE assigned the dam a Safety Action Classification (DSAC) II which is defined as "Urgent (Unsafe or Potentially Unsafe)". The rating is attributed to concerns about possible increased seepage at the toe of the dam, and an undetermined flow rate at the river spring downstream, and potential flow channels through limestone below the spillway during pool events above . Because of this rating, the USACE has implemented risk reduction measures which include increased monitoring, updating emergency operation plans and reducing the water level in the reservoir.

Mimetes palustris is an endemic species restricted to the Kleinrivier Mountains, Western Cape province of South Africa, where it can be found between the Platberg in the Fernkloof Nature Reserve near Hermanus in the west and slightly east of the Rocklands Peak. Here it grows in a vegetation type called Overberg Sandstone Fynbos, at an altitude of 600–900 m (2000–3000 ft). Mimetes palustris can only be found on south-facing slopes in part-shade in locations where an updraught from the sea create cool and moist air during summer. At the edge of seepage zones it can be found in combination with Brunia alopecuroides, Erica hispidula, Roridula gorgonias, and Villarsia ovata.

However, these sanitary facilities are not built per the design specifications, or they are not suitable for the geophysical characteristics, which results in seepage into the fresh water lens and run- off into coastal waters. A project involving the South Pacific Applied Geoscience Commission (SOPAC) is constructing composting toilets and improving the treatment of sewage sludge from septic tanks on Fongafale in order to reduce the leakage from septic tanks into groundwater, and the ocean and lagoon. In November 2013 the World Bank announced US$6 million in funding to improve the operational safety of the Funafuti International Airport and associated infrastructure. An 800,000-litre water cistern will be constructed to improve storage of drinking water.

This station opened just after midnight on November 23, 1904, as part of the IRT's original system. It was completed along with the rest of the IRT Lenox Avenue Line, then known as the East Side Subway or East Side Branch, south of 145th Street. Starting on March 2, 1998, the tunnel was reconstructed along with the cracked tunnel floor, and the 116th Street station was closed for a complete renovation. This was done to correct a major water problem that had existed for many years due to the presence of the Harlem Creek and other underground streams, which caused extensive flooding, water damage, and seepage problems that occasionally contributed to severe service disruptions.

Work on the foundations continued but water penetration of cylinders A and C became a concern caused by general seepage and then by small leaks. By 19 August 1946, the Engineer in Chief reported: "Water was coming in fairly rapidly" and on 24 August two divers worked in relays plugging the leak, but the depth was great and the job was not successful. Divers working in of water could only generally work for a total time of 2 hours 50 minutes in tw The main use of the crane has been in the removal and refitting of gun turrets. The crane comprises an asymmetric horizontal steel boom, radius , swiveling on a square section steel tower.

In very old lime, mortar or concrete structures, possibly tens or hundreds of years old, the calcium hydroxide (Ca(OH)2) may have been leached from all the solution seepage paths and the pH could fall below pH 9. This could allow a similar process to that which creates speleothems in limestone caves [Equations to ] to occur. Hence, CO2 rich groundwater or rainwater would form carbonic acid (H2CO3) (≈pH 7.5 – 8.5)Hartland, A, Fairchild, I J, Lead, J R, Dominguez-Villar, D, Baker, A, Gunn, J, Baalousha, M and Ju-Nam, Y, (2010).

It also meant the Evans party of three had to try to split the ration pack (at a time when they were cold and tired and later when one member was suffering from scurvy) to leave an allowance for the fifth man in Scott's party. This also will have affected the seepage of fuel from cans which were opened and then re-closed and left for several weeks before Scott's team got to them. Moreover, for some unexplained reason Scott had ordered Evans's team to cache their skis a week before so Bowers (the fifth man) walked to the pole and back to the cached skis (360 miles) while the rest of Scott's team skied.

The MWCD estimates that if the Mohawk Dam were to fail during a flood, the water normally held back could cost 307 people their lives and up to $449 million in property damage. According to the MWCD, the dam's greatest problem is the inherent downstream seepage that occurs with most earthen dams. In the case of the Mohawk Dam, this condition is exacerbated by the fact that it was built on highly permeable land, which could cause instability if too much water were to seep through the lower part of the dam. A rehabilitation and repair plan to stabilize the structure has not yet been established, nor has an official cost-estimate been prepared.

Males reach reproductive maturity by 3.5 yrs old, and females mature by 4.5. Mating occurs in fall and spring, and involves the males biting on to the female's tail to initiate the mating process. In a typical Plethodontidae mating behaviour, the pair will then walk in a line with the female straddling the male's tail and the male will then deposit a spermatophore on the ground and guide the female to it so she may pick it up with her cloaca. This is how they achieve internal fertilization, and the female will lay a clutch averaging 3-10 eggs in a seepage area or wherever she can find moist ground and stay nearby to protect them.

These surveys established that the center section had moved downstream and toward the eastern abutment. Although this investigation was insightful and informative, the theory, along with others which hypothesized an appreciably increasing amount of seepage just prior to the failure, becomes less likely when it is compared against the eyewitness accounts of the conditions in the canyon and near the dam during the last thirty minutes before its collapse. Grunsky hypothesized, though failed to explain, the action of the dam tilting as he described. This action would have the dam in motion as a singular unit while conversely, testimony given at the Coroner's Inquest indicates that the dam was fractured transversely in at least four places.

An agreement was signed jointly by Governments of Maharashtra, Karnataka and Andhra Pradesh on 14 April 1976 to spare 15 thousand million cubic feet (TMC) of Krishna water to Chennai city. Following this, an accord between Andhra Pradesh Government and Tamil Nadu Government was signed on 18 April 1983 for drawing 15 TMC of Krishna water to Chennai City from Sri Sailam Reservoir to be conveyed through Somaseela and Kandaleru Reservoirs. Ultimately a net quantity of 12 TMC (after loss of 3 TMC en route in evaporation and seepage) will reach the Tamil Nadu border. Thus the water from Krishna river were stored in Sholavaram lake as well as Poondi Reservoir for drinking purposes.

Gas hydrates have been sampled at the Amsterdam and Kazan mud volcanoes, and high methane levels have been recorded above the seafloor. Several provinces of the Nile deep-sea fan have been explored recently. These include the very active brine seepage named the Menes Caldera in the eastern province between 2,500 m and 3,000 m, the pockmarks in the central area along mid- and lower slopes, and the mud volcanoes of the eastern province, as well as one in the central upper slope (North Alex area) at 500 m depth. During these first exploratory dives, symbiont-bearing taxa that are similar to those observed on the Olimpi and Anaximander mud fields were sampled and identified.

The HLC was designed to carry nearly three-quarters of a billion gallons of water per day, but actually averages only 71 million gallons. The canal today has a water capacity of . When the Rocky Mountain Arsenal was built in 1942, a lateral was built off the HLC (at about mile 64) in order to supply water to the chemical weapons manufacturing center, and until about 2008, the Rocky Mountain Arsenal National Wildlife Refuge was the furthest-downstream customer that was still taking water delivery via the HLC. However, the canal does not provide a very efficient method of delivering water; Denver Water estimates 60-80% of water in the canal is lost to seepage and/or evaporation.

While often cited by literature that the flame chub inhabits spring-fed streams, shallow seepage waters, and springs, usually over gravel in areas of abundant aquatic vegetation, substrate the species found over can vary from bedrock to rubble to mud and may be found in areas of low flow near the bank of large streams. A study by P. W. Shute notes that although the flame chub is often described as a spring-dwelling species, only 37 of 231 collection localities were springs. Despite this, the species can still be found primarily in association with spring heads, as most collection localities are found within watersheds that are fed by springs. Most documented records of this species are found in small streams.

The quantity of marble reserves in the region is estimated to be 55 million tonnes by the state government. About 120 thousand tonnes of the marble are produced annually from over 400 mines in the region. Makrana marble has a high percentage of calcium and is therefore resistant to water seepage. The water absorption of Makrana marble is said to be the lowest among all types in India, and the marble is claimed to contain 98 percent of calcium carbonate and only two percent of impurities, this property of Makrana marble helps it to stay the same proportion of white for a long period of time and because it contains 98 percent of calcium the polish of this marble is considered in the best.

The company will also have to pay a fine of $800,000, supply 21 households with hook-ups to municipal water systems, and conduct an environmental impact study on the area." FirstEnergy is required to clean up the site by 2031, but in April 2014, FirstEnergy agreed to have the site cleaned by 2028. FirstEnergy is required to cover the ash with two layers of impermeable "geotextile" sheeting to keep unhealthy chemicals from entering the local groundwater, it must monitor noise, odors and particulate emissions, conduct quarterly reconnaissance of contaminated water seepage from the lake and take corrective actions when necessary. According to the PADEP, FirstEnergy is also required to monitor the site "for as long as environmental problems remain at the site.

Yucca Mountain lies in a region of ongoing tectonic deformation, but the deformation rates are too slow to significantly affect the mountain during the 10,000-year regulatory compliance period. Rises in the water table caused by seismic activity would be, at most, a few tens of meters and would not reach the repository. The fractured and faulted volcanic tuff that Yucca Mountain comprises reflects the occurrence of many earthquake-faulting and strong ground motion events during the last several million years, and the hydrological characteristics of the rock would not be changed significantly by seismic events that may occur in the next 10,000 years. The engineered barrier system components will reportedly provide substantial protection of the waste from seepage water, even under severe seismic loading.

Dahla Dam in June 2012 After completion of the dam in 1952, it functioned well for many decades. However, the irrigation system and its operation was neglected during the 1980s Soviet occupation. A technical appraisal of the status of the project carried out by experts from Agriculture and Agri-Food Canada in 2008 revealed that the siltation in the reservoir had resulted in reduction of the storage capacity by 34%, irrigation system had deteriorated resulting in loss in canal discharge to the extent of 70% on account of siltation, evaporation, seepage and other defects. The intake tower of the dam was not functioning properly and control valves were leaking, spillway capacity to discharge flood waters was inadequate, and there was no operational plan.

The findings of the investigation of 1979 were that the entire interior of the chapel, but particularly the ceiling, was covered with a grime of candle smoke comprising wax and soot (amorphous carbon). Above the windows (the main source of ventilation), the lunettes were particularly stained from the smoke and exhaust fumes of the city, being "much dirtier than the ceiling proper". The building was a little unstable and had already shifted considerably prior to Michelangelo's work of 1508, causing cracking of the ceiling, the crack in the "Judith" pendentive being so large that it had to be filled with bricks and mortar before painting. The upper part of the ceiling provided Michelangelo an irregular surface due to cracks and water seepage.

A diameter tunnel, later expanded to , was dug around the south side of the O'Shaughnessy Dam site, and a timber crib cofferdam diverted the waters of the Tuolumne River into the tunnel during construction. The riverbed on the site of the future dam was excavated over before hitting the granite bedrock. A retaining wall was poured on the upstream side to prevent water seepage into the foundation hole, and the granite was scoured and artificially roughened to prepare for receiving concrete. The dam as initially completed in May 1923 The concrete for the dam was processed in a plant located shortly upstream from the construction site, with sand and rock excavated from abundant alluvial deposits in the Hetch Hetchy valley.

Sediment failure on glacial margins as a result of glacial loading is common and operates on a wide spectrum of dimensions, ranging from relatively small scale mass wasting processes in fjords to large scale slides covering several thousand square kilometres. Factors which are significant in glacial loading induced landslides are the flexing of crust due to the loading and unloading of a fluctuating ice front, variation in drainage and groundwater seepage, quick deposition of low plasticity silts, rapid formation of moraines and till above hemipelagic interstaidal sediments. An example where glacial loading leads to submarine landsliding is the Nyk slide of northern Norway.Lindberg, B., Laberg, J. S. & Vorren, T. O. (2004) The Nyk Slide – morphology, progression, and age of a partly buried submarine slide offshore northern Norway.

Traditional family-managed taankas are constructed by digging a hole of 3 to 4.25 meter diameter in the ground and plastering it with lime mortar cement about 6 mm thick, followed by a cement plaster of about 3 mm thickness. Most modern taankas have a capacity of around 21,000 liters but larger ones can be constructed where resources are available. Commonly, the catchment area, known as an agor, is a concave cemented funnel-like slope directing water into a collection pit that reduces the sediment load of water before it enters the underground cistern via a suitable mesh supported by bars in an angle iron frame to filter out other large debris. The micro-catchment avoids seepage and prevents erosion, and is fenced to restrict animal entry.

The Corps identified safety and seepage problems with the dam in 2009, and has assigned it a Dam Safety Action Class rating of DSAC II, or "Urgent". The reservoir it creates, Ball Mountain Reservoir, has a normal water surface of , a maximum capacity of , and a normal capacity of . Recreation includes fishing (for stocked Atlantic salmon, smallmouth bass, and trout), camping at 111 campsites in nearby Winhall and Jamaica, and activities at the adjacent Jamaica State Park. The river between Ball Mountain Lake and downstream Townshend Lake (also operated by the Army Corps of Engineers) is used for white water boating during releases from the Ball Mountain Dam, usually occurring during one weekend in April and one weekend in September.

Both evaporation loss and seepage loss take place in manmade water works such as canals, reservoirs, ponds, tanks, percolation ponds / meadows, sewage treatment plants, water harvesting / ground water recharging works / contour bunding of fields, etc. Many times land is used for enhanced ground water charging from rain water by constructing contour bunds to the fields for better soil moisture and salt’s leaching from the top soil. All these works are either manmade reservoirs or manmade other works as explained in Clause III B & C of final order of GWDT. Water reservoir creates space to store water for various requirements such as domestic, municipal, irrigation, industrial, production of power, navigation, carryover storage in future year’s use, pisciculture (fish rearing), wild life protection and recreation purposes .

The accumulation of moisture and water seepage caused serious inconveniences to the master builders. Besides that, most of the stones of the cathedral are of poor quality rock, a limestone, with little resistance to atmospheric agents. In addition, the subtlety of its style is a challenge to its construction materials; the numerous supports are extremely fragile, the lines are reduced to a total optimization, to such a degree that several architects of the time questioned whether such a project could remain standing. This almost unreal structure, together with the poor quality of the stone and its poor foundation, forced it to suffer constant interventions and restorations from the fifteenth century on, changing the temple into a European model for transformative intervention, restoration and conservation.

The minaret tower (centre) stands between the Imam's residence (left) and the main entrance (right) Masjid Hajjah Fatimah contains within its walled compound a prayer hall, a mausoleum, the quarters of an Imam, an ablution area, several annexes and a garden. The building style is eclectic, perhaps its most unusual feature is a distinctive minaret designed in a European style with Doric pilasters, in direct contrast to the Islamic dome above the prayer hall. The tower leans about six degrees off centre due to moisture seepage, shifting of bricks used in the construction of the tower, and the sandy soil on which it sits. The minaret is flanked by two houses in European style but with Chinese features, for example in its windows and woodwork.

The Tank Stream itself was only a tiny rivulet which rose in marshy ground skirting the western slopes of the ground which later became Hyde Park. The seepage from the bed-joints of the underlying sandstone around the upper portion of its catchment, which headed about the centre of the park, filtered through the soil to form a definite channel near King and Pitt Streets. The area now occupied by Hyde Park was relatively flat, rising slightly along the centre and elevated. We know it was timbered, as was the rest of the topography, from the early drawings of the settlement, and Director of the Botanic Gardens, Sydney J. H. Maiden has suggested that the dominant species were probably white or brittle gum (Eucalyptus micrantha), blackbutt (E.

Groundwater flow is important parameter for consideration in the design of waste rock basins for mining operations. Waste rock is heterogeneous material with particles varying from boulders to clay-sized particles, and it contains sulfidic pollutants which must be controlled such that they do not compromise the quality of the water table and also so the runoff does not create environmental problems in the surrounding areas. Aquitards are clay zones that can have such a degree of impermeability that they partially or completely retard water flow. These clay lenses can slow or stop seepage into the water table, although if an aquitard is fractured and contaminated then it can become a long-term source of groundwater contamination due to its low permeability and high HRT.

Hydrolock is common on radial and inverted engines (cylinders pointing downwards) when the engine sits for a long period. Engine oil seeps down under gravity into the cylinder through various means (through the rings, valve guides, etc.) and can fill a cylinder with enough oil to hydrolock it. The seepage effect can be observed by the blue-white smoke commonly seen when a radial engine starts up. In order to prevent engine damage, it is universal practice for the ground crew or pilot to check for hydrolock during pre-flight inspection of the aircraft, typically by slowly cranking the propeller for several turns, either by hand or using the starter motor, to make sure the crankshaft cycles normally through all cylinders.

Once joined, the river flows in a northerly direction, past Fletland Mill, a former grain mill which was built in 1759, and Kate's Bridge weir, where a modern bridge carries the A15 road over it. This bypasses a single-arched bridge built in the late 1700s, which has a female head carved on the keystone of the western face, presumed to be the Kate after whom the bridge is named. Beyond the bridges, the river becomes a typical Fens high level carrier, embanked on both sides and partially straightened, with counter drains on both sides of the channel, to collect seepage through the banks, as the normal water levels are higher than the surrounding land. At Tongue End the waters of the Bourne Eau join.

The Ridgeway mine recovery has been an ecological success with minimal seepage of acid water into the environment, a stark contrast to the nearby Barite Hill and Brewer gold mines that were both declared Superfund sites after being abandoned by their owners. Both mine pits are expected to fill with water by 2020 and the public may be able to access the South Pit Lake. To make the lake safe for public use and to control environmental hazards management hopes to turn it into a meromictic lake, a self-regulated lake with distinct layers of water that do not mix. To see if this was possible the South Pit Lake's physical, chemical and biological properties were measured in a limnology study from 2000 to 2004.

As illustrated by the sketches, seepage began at a point several hundred meters above the falls and, owing to the horizontal bedding of the rock, it first took a path at right angles to the river course, then descended from bed to bed to the bottom of the falls. The porous, soft nature of the rock favored the rapid enlargement of the underground channel, and eventually the entire stream followed this course. Subsequent erosion and caving had greatly decreased the length of the underground channel and produced the short canyon above the present entrance portal. Owing to the thinness of the roof, the first part of the tunnel caved rapidly, whereas the erosion and caving of the lower part was much slower.

As with others, Mulholland inspected it, judged it to be another contraction crack and ordered it filled with oakum and grouted to seal off any seepage. At the same time another fracture appeared in a corresponding position on the eastern portion of the dam, starting at the crest near the last spillway section and running downward at an angle for sixty-five feet before ending at the hillside. It too was sealed in the same manner. Both of these fractures were noted to be wider at their junction with the hillside abutments and narrowed as they angled toward the top of the dam. The reservoir continued to rise steadily until early February 1928, when the water level was brought to within one foot of the spillway.

About of the catchment is in Turkey, in Armenia,Armenia is entirely in the Kura River catchment in Georgia, in Azerbaijan,Problems of Transboundary Water Management in Azerbaijan report states that 65% of Azerbaijan is drained by the Kura and about are in Iran. At the confluence with the Aras River, the drainage area of the tributary is actually larger than the Kura by about 4%, and it is also longer. However, because of the more arid conditions and equally intensive water use, the discharge of the Aras is much less than the Kura, so downstream of the confluence the river is still called the Kura. About 52% of the river's flow comes from snowmelt and glaciers, 30% comes from groundwater seepage, and roughly 18% from precipitation.

Prior to the center being built, visitors to the Capitol had to line up in the basement of the Cannon House Office Building or the Russell Senate Office Building. The new underground facility provides a grand entrance hall, a visitors theater, room for exhibits, and dining and restroom facilities, in addition to space for building necessities such as a service tunnel. A large-scale Capitol dome restoration project, the first extensive such work since 1959–1960, began in 2014, with completion scheduled before the 2017 presidential inauguration. As of 2012, $20 million in work around the skirt of the dome had been completed, but other deterioration, including at least 1,300 cracks in the brittle iron that have led to rusting and seepage inside, needed to be addressed.

The occurrence of chemosynthetic organisms dependent on hydrocarbon seepage has been documented in water depths as shallow as 290 m (951 ft) (Roberts et al., 1990) and as deep as 2,744 m (9,003 ft). This depth range specifically places chemosynthetic communities in the deepwater region of the Gulf of Mexico, which is defined as water depths greater than 305 m (1,000 ft). Chemosynthetic communities are not found on the continental shelf although they do appear in the fossil record in water shallower than 200 m (656 ft). One theory explaining this is that predation pressure has varied substantially over the time period involved (Callender and Powell 1999). More than 50 communities are now known to exist in 43 Outer Continental Shelf (OCS) blocks.

Scientific research over the years also reveal that Telbal, Botkal, and sewage drains are responsible for a substantial influx of nitrogen and phosphorus into the lake. Quantitatively, fifteen drains and several other sources have released a total of 156.62 tonnes (56.36 tonnes by drains alone) of phosphorus, and 241.18 tonnes of inorganic nitrogen into the lake from a discharge of 11.701 million cubic metres /year. Non-point sources, such as seepage and diffused runoff, also add to this pollution and have been recorded as further adding 4.5 tonnes of total phosphates and 18.14 tonnes of nitrogen (NO3–N and NH4–N) to the lake. Based on the values mentioned above, it has been inferred that the water quality of the lake has deteriorated.

Shortly after commissioning, Arapuni was closed for two years while a water seepage problem was investigated and the headrace lined. The station, with the addition of a fourth turbine, was recommissioned in May 1932. The Arapuni Gorge during the construction of the power station, 1929 The Arapuni Suspension Bridge, just downstream from the power station, was opened in 1926. It gave access from 'top camp' (which eventually became the Arapuni township) on the true right to the power station construction site on the true left of the Waikato River. Originally, Electricity from Arapuni was stepped up to 110,000 volts and transmitted along two lines (one single-circuit and one double-circuit) to Penrose substation in Auckland, with intermediate substations at Hamilton and Bombay.

The EPA estimates there are 650,000 such Class V wells in place across the United States. Map of the northwestern shore of the island of Maui, highlighting the location of the Lahaina Wastewater Reclamation Facility and its proximity to the shoreline In the present case, the Lahaina Wastewater Reclamation Facility in Maui County, Hawaii treats wastewater from homes and businesses. The facility is authorized by the EPA and the Hawaii Department of Health under the SDWA to inject the reclaimed water into four Class V wells on the island, with an average total effluent of per day. Because of the geologic nature of Hawaii, it was estimated that more than 90% of this water eventually enters the surrounding ocean through seepage.

Construction of dam wall, 1939The construction of Canning Dam ended a long period during which Perth's water supply was generally unsatisfactory in quality (either due to salinity or bacterial pollution or both) and in quantity. The project, the biggest public works program of the decade, stimulated significant growth in the local economy and provided desperately needed work for around five hundred men. Several innovative design concepts and construction methods which were new to Australia were introduced on the project, while others which were used on the nearby Wellington Dam, were improved upon at the Canning dam site. At the Canning Dam and indeed all dams, care had to be taken to prevent water seepage between the foundation rock and the structure of the dam.

At Norton, it passes the site of Norton mill and Norton Priory before passing under Tanpit bridge, a single arched bridge constructed of dressed stone with brick lined soffits in the early nineteenth century. By the time it reaches another railway line, it is only above sea level, and the channel is embanked on both sides to prevent flooding of the surrounding low- lying land. Beyond Went bridge, where the A19 road crosses, the river used to take a winding route round the southern edge of Stubbs Common, but a new straight channel has been made, which has counter drains on either side, to collect seepage through the banks. Lake Drain joins the river at Lake Mouth, just beyond the point at which the old course of the river rejoins the new.

These perplexing results have since led the shipboard researchers to believe that gas hydrates were present in the core and would explain the high volumes of gas locked in the small quantity of water filling the sediment pore spaces and the long degassing time. During the R/V Sonne SO174 research cruise in 2004, remote sensing results guided researchers to the discovery of oil, gas, and asphalt seepage on the top of one knoll in the northern tip of the Campeche Knolls province. This knoll was named Chapapote, the Aztec word for “tar,” and is located at 21° 54’ N by 93° 26’ W in approximately 1.8 mi (3, 000 m) water depth. Extensive surface deposits of solidified asphalt are present at Chapapote, with one subcircular-shaped flow measuring at least across.

Floodwaters up to deep submerged at least 70% of nearby Crooked Island, where the storm left widespread structural damage. The hurricane "completely destroyed" a Bahamas Electricity Corporation power plant, where two large diesel tanks were shifted off their bases, allowing more than 10,000 gallons of fuel to leak into the ground. In the days following the storm, about 100 evacuees—including 46 from Crooked Island—were flown to New Providence, where several of them sought medical attention. On Long Island and Crooked Island, septic tank seepage contaminated residential wells, leaving residents without clean drinking water. Both areas still had extensive standing water on October 7. Acklins endured severe flooding, with many homes inundated and numerous calls for rescue; the island's sea barrier was breached by 9:00 a.m.

This lava dam is over 300 m (1,000 ft) in thickness and about 2 km (1.2 mi) wide where it impounds the lake. A series of lava outcrops along the northwestern shore of the lake form the numerous tiny Battleship Islands, several of which have been connected to the shore by simple man-made stone causeways. The turquoise colour of the lake's water is due to glacial flour suspended in the meltwater from its two primary inflows, the large Sphinx Glacier to the east and the Sentinel Glacier to the south on the flanks of Mount Garibaldi. Throughout most of the year, outflow from Garibaldi Lake occurs only via seepage through cracks in the lava dam, with Rubble Creek appearing from springs at the base of The Barrier.

After several unsuccessful salvage attempts by the original owners and a Miami man who bought her from them, the ship was abandoned and became a menace to those people daring enough to board and wander through her, as well as a concern for the motel owner whose guests were annoyed by the sightseers and kept awake at night by clanging noises from the ship. Oil seepage fouled the water and beach and one fire broke out on the ship. Local residents and officials became concerned about the danger of further damage to the coral reef by the ship as well as the discharge of large quantities of bunker oil from the ship if she broke up. The Army Corps of Engineers became involved in dismantling the ship and removing the oil.

With a grant from the National Endowment for the Arts, Selick was able to make the short film Seepage, which won an award.IMDb: Best short film at Chicago International Film Festival 1982 Then he spent several years freelancing in the Bay Area, directing still-famous commercials for the Pillsbury Doughboy and Ritz Crackers, and sequences of John Korty's animated feature Twice Upon a Time. He also storyboarded fantasy sequences for Walter Murch’s Return to Oz and Carroll Ballard's Nutcracker: The Motion Picture (with designs by Maurice Sendak). When he created an acclaimed series of MTV station IDs and an award-winning six-minute pilot for an animated series called Slow Bob in the Lower Dimensions, Selick attracted the attention of director Tim Burton, whom he had known at CalArts, and was catapulted into features directing.

One problem that prevented the use of the bell was the seepage of water into the wooden driveshaft case, causing it to expand and warp. While the exact date the clock stopped regularly functioning is unknown, after about 30 years of being out of service the mechanism was restored in the Spring of 2018 by local steeplejack and arborist Dave Cotton, and a UMass professor emeritus of English, John Nelson, who worked on the clock of the Old Chapel previously. On July 4, 2018, the clock was restarted with new face lighting and repaired electrical systems, all from donated components and time. Due to problems with its mechanics, the bell however does not function and no immediate plans have been put into place to restore it in the foreseeable future.

A large earthfill dam, the O'Sullivan Dam (also referred to as the Potholes Dam) was constructed from 1947 to 1949, forming Potholes Reservoir, which serves as a central point in the CBP for storage of irrigation water, natural runoff, and irrigation-return flow, allowing irrigation water reuse throughout the southern CBP area. Potholes Reservoir releases water through canals and has no perennial outlet to Lower Crab Creek. Hence today the water in Lower Crab Creek comes from ground-water seepage from Potholes Reservoir and irrigation, from the Goose Lake Wasteway, and from tributary inflows downstream of the O'Sullivan Dam.Columbia Basin Project , Bureau of Reclamation History Program Research on Historic Reclamation Projects The water table in this section is variable but generally high due to the low elevation and irrigation runoff.

Tailings do not have to be stored in ponds or sent as slurries into oceans, rivers or streams. There is a growing use of the practice of dewatering tailings using vacuum or pressure filters so the tailings can then be stacked. This saves water which potentially reduces the impacts on the environment in terms of a reduction in the potential seepage rates, space used, leaves the tailings in a dense and stable arrangement and eliminates the long-term liability that ponds leave after mining is finished. However although there are potential merits to dry stacked tailings these systems are often cost prohibitive due to increased capital cost to purchase and install the filter systems and the increase in operating costs (generally associated electricity consumption and consumables such as filter cloth) of such systems.

The GNR were the owners of the Witham Navigation, and the money was for maintenance of the banks of the river. The Greetwell Level covered an area of around , but the amount of water that had to be managed was disproportionate, as water from the higher ground to the north found its way into the drains, and the banks of the Witham were porous, resulting in significant seepage out of the river and into the drains. Responsibility for the North Delph, a catchwater drain running parallel to the river for from Lincoln to Horsley Deeps, passed from the GNR to the Commissioners. Before the Act, the land had been drained by a wind pump, but the Commissioners built a steam pumping station where the South Delph and the old course of the River Witham met.

So the actual return flows available would not exceed 10% of primary water supply of the river. Thus as an exception in case of irrigation use, Clause II B aptly says that the extent of return flows shall not be deducted from the water lifted / diverted for the irrigation use (clause III A i). Also, it implies that return flows deduction is applicable for water uses under domestic & municipal water supply (clause III A iii) and industrial purpose (clause III A iv) at the rate of 80% and 97.5% respectively. Clause III C very clearly says seepage and evaporation water losses to the extent of actual depletion from a manmade reservoir shall be accounted under water use in each water year whether stored water is put to use or not.

The deep, anoxic water of the Black Sea originates from warm, salty water of the Mediterranean. Lake Texoma, a reservoir on the border between the U.S. states of Texas and Oklahoma, is a rare example of a brackish lake that is neither part of an endorheic basin nor a direct arm of the ocean, though its salinity is considerably lower than that of the other bodies of water mentioned here. The reservoir was created by the damming of the Red River of the South, which (along with several of its tributaries) receives large amounts of salt from natural seepage from buried deposits in the upstream region. The salinity is high enough that striped bass, a fish normally found only in salt water, has self-sustaining populations in the lake.

In 1847 Young had his attention called to a natural petroleum seepage in the Riddings colliery at Alfreton, Derbyshire from which he distilled a light thin oil suitable for use as lamp oil, at the same time obtaining a thicker oil suitable for lubricating machinery. In 1848 Young left Tennants', and in partnership with his friend and assistant Edward Meldrum, set up a small business refining the crude oil. The new oils were successful, but the supply of oil from the coal mine soon began to fail (eventually being exhausted in 1851). Young, noticing that the oil was dripping from the sandstone roof of the coal mine, theorised that it somehow originated from the action of heat on the coal seam and from this thought that it might be produced artificially.

Although many designers and builders of dams had become aware of this phenomenon by the late 1890s to early 1900s, it was still not generally well understood or appreciated. Nevertheless, it was becoming a matter of debate and a concern to dam builders of this era that water from a reservoir could seep under a dam and exert pressure upward. Due for the most part to inadequate drainage of the base and side abutments, the phenomenon of uplift destabilizes gravity dams by reducing the structure's "effective weight", making it less able to resist horizontal water pressure. Uplift can act through the bedrock foundation: the condition most commonly develops where the bedrock foundation is strong enough to bear the weight of the dam, but is fractured or fissured and therefore susceptible to seepage and water saturation.

In 2000 the Conestee Foundation, a 501(c)(3) conservation organization, was formed to lead the revitalization of the lake as a wetlands through the development of the nature park; and the foundation used settlement funds from a June 1996 Colonial Pipeline spill to purchase the lake and the dam. Once safety studies of the brownfield were complete, it was determined that no harm would result if the toxic sediment and dam were left in place,; Cary, 4A. The toxic wastes include heavy metals (such as lead), pesticides, and cancer-causing chemical compounds such as PCBs and PAHs. though in December 2016, inspectors from the state Department of Health and Environmental Control determined Conestee Dam, which is not keyed into the bedrock, to be in poor condition due to deterioration of mortar and water seepage.

The NWSC was founded in 1985 in the root of the New Youth Study Society in Tsuen Wan which was a social group formed by activist Lau Shan-ching and other graduates from the University of Hong Kong aiming at providing education for workers and raise their social consciousness. However, as the government set up night courses for adults in the early 1980s, the number of workers attended to the society's courses dropped. The lecturers and students in the society decided to participate in the newly established District Board elections as the government introduced constitutional reform. Leung Yiu-chung, lecturer of the New Youth Study Society, led the Kwai Chung residents who were affected by concrete spalling and seepage in their public housing estates to demand solutions from the Housing Department.

Over of oil was eventually recovered, all from seepage from poorly cased wells. Production from the field peaked in 1929, with a total production of of oil. That year also saw the spudding of well Yates 30-A, which blew out with the spectacular flow of per hour, and over 200,000 in a day, setting the world record; even the Lakeview Gusher at the Midway- Sunset field in California, which spewed a total of approximately in its 18-month uncontrolled run, only attained half of that daily flow rate. Because of the high production rate from the field and lack of storage and transport, the State of Texas Railroad Commission – the entity that oversees petroleum production – required a proration of the field for the first time in Texas history.

After a bill that would have provided funds to protect the site failed, then-President Lyndon B. Johnson signed an Executive Order that authorized funding for the Army Corps of Engineers to build a levee around the site to protect it from the imminent flooding caused by construction of the Lower Monumental Dam. Late that year, Daugherty left the dig, leaving Fryxell to lead the project. Within three days of the closure of the Lower Monumental Dam in February 1969, the site was completely underwater, due to the seepage of water through thick layers of gravel that had not been accounted for. However, as the site was being flooded, the excavation team laid down plastic sheeting topped with gravel in the hopes of being able to return to the dig in the future.

In 1992 Jagannathan started working on issues concerned with prawn farms along the coast of Tamil Nadu. This time the problems were not from the local landlords, but from large industries from cities such as Chennai, Mumbai, Kolkata, Delhi and Hyderabad which occupied large areas of land for aquaculture along the coast, which not only threw the landless labourers out of employment but also converted fertile and cultivable land into salty deserts after a few years when the prawn companies moved on. The prawn farms also caused heavy seepage of seawater into the groundwater in the neighbourhood, thus the local people were deprived of clean drinking water resources. The result is that even more small farmers sell their meagre land- holdings to multinational prawn companies and move to the cities, filling urban slums.

Yanar Dag view by the road side The reason offered for the Yanar Dag fires is the result of hydrocarbon gases emanating from below the earth's surface. Apart from Yanar Dag, the most famous site of such a fire is the Fire Temple near Baku, off the Greater Caucasus, which is a religious site known as an ateshgah, meaning temple of fire. It has also been inferred that such fires could be the cause for "thermal metamorphism." Like the flames of Yanar Dag, the Ateshgah of Baku's flame was a manifestation of the seepage of natural gas from porous strata, but the natural flow at Ateshgah ceased some time ago and the flames seen there now are fed from a gas main for touristic effect - whereas those at Yanar Dag are still entirely natural.

Paste tailings is a modification to the conventional methods of disposal of tailings (pond storage). Conventional tailings slurries are composed of a low percent of solids and relatively high water content (normally ranging from 20% to 60% solids for most hard rock mining) and when deposited into the tailings pond the solids and liquids separate. In paste tailings the percent of solids in the tailings slurry is increased through the use of paste thickeners to produce a product where the minimal separation of water and solids occurs and the material is deposited into a storage area as a paste (with a consistency somewhat like toothpaste). Paste tailings has the advantage that more water is recycled in the processing plant and therefore the process is more water efficient than conventional tailings and there is a lower potential for seepage.

Starting on March 2, 1998, the tunnel was reconstructed along with the cracked invert (tunnel floor). This was done to correct a major water problem that had existed for many years due to the continued presence of the Harlem Creek and other underground streams, which caused extensive flooding, water damage, and seepage problems that occasionally contributed to severe service disruptions. The project cost $82 million and was finished on October 12, 1998. During the reconstruction, many trains were rerouted via the IRT Lexington Avenue Line, while the trains were rerouted to the 137th Street–City College station on the IRT Broadway–Seventh Avenue Line. Each of the two Lenox Avenue Line tracks were alternately taken out of service, the 116th Street station was closed, and supplemental shuttle bus service connecting to other lines in the area were provided for much of this time.

Clause II declares each of above purpose is water use along with the evaporation loss from the associated storage. The sum of all storages (without repetition) associated with all water uses is the total storage of all manmade reservoirs and other works. The loss of water by seepage is due to natural cause/ phenomenon from the manmade reservoirs and other manmade works. Clause III A defines how the water use is quantified / measured for domestic, municipal, irrigation, industrial, production of power and diversions outside the Godavari river basin area. Clause III B defines how a water use from the manmade reservoirs and other works are measured for remaining uses (navigation, pisciculture, wild life protection and recreation purposes) which are not covered under Clause III A. Every manmade reservoir’s water is invariably used for pisciculture, wild life survival, navigation, recreation, etc.

During this maneuver, Solovyev and Vinogradov opened a pressure regulation valve to allow air into the Spektr module to see if STS-89 crew members could detect seepage or debris particles that could indicate the location of the breach in the damaged module's hull. During the flight, Wetherbee and Bloomfield fired small jet thrusters on Atlantis to provide data for the Mir Structural Dynamics Experiment (MISDE), which measures disturbances to space station components and its solar arrays. Other experiments conducted during the mission were the Commercial Protein Crystal Growth investigation; the Cell Culture Module Experiment (CCM-A), the Cosmic Radiation Effects and Activation Monitor (CREAM) and the Radiation Monitoring Experiment-III (RME-III); the Shuttle Ionospheric Modification with Pulsed Local Exhaust (SIMPLE) experiment; and the Midcourse Space Experiment. Two NASA educational outreach programs were also conducted, Seeds in Space-II and KidSat.

The large outlet tower structure used to release water from Lake McConaughy (2002) Kingsley Dam is located at the east end of Lake McConaughy and was the second largest hydraulically filled earthen dam in the world (behind Fort Peck Dam) on the time of its completion. The dam was named for George P. Kingsley, a Minden, Nebraska banker, who worked with C. W. McConaughy to promote the project. The dam was built by pumping sand and gravel from the river bed to form its sides, while pumping a mixture of loess soil and water into the center of the structure to form its watertight core. Seepage of water under the dam is prevented by a wall of interlocked sheet piling driven 30 to deep and tied into the impervious Brule clay formation that lies beneath the dam.

That such extensive wetlands existed in this site served likely to be a stimulus for the original growth of Lhasa city as the humidity the wetlands provided in the narrow valley makes the otherwise dry air of Lhasa more moist than the surrounding Tibetan Plateau. The wetlands historically covered about , being the flat drainage area between the base of the Gangdise Mountains east of Lhasa City and the Lhasa River (Kyi Chu). A slightly raised northern riverbank prevented the water from directly draining to the river, and along this raised bank a series of structures were historically built—most notably the summer palace of the Dalai Lama the Norbulingka (Jewel Park). This holy retreat site having especially rich vegetation and unusually tall trees because of its better water supply due to underground seepage from the wetlands to the river.

It covers a wide range of physical and computational issues in the field of porous/fractured-media modeling. The book starts with a more general theory for all relevant flow and transport phenomena on the basis of the continuum mechanics, systematically develops the basic framework for important classes of problems (e.g., multiphase/multispecies non-isothermal flow and transport phenomena, variably saturated porous media, free-surface groundwater flow, aquifer-averaged equations, discrete feature elements), introduces finite element methods for solving the basic multidimensional balance equations, in detail discusses advanced numerical algorithms for the resulting nonlinear and linear problems, and completes with a number of benchmarks, applications and exercises to illustrate the different types of flow, mass and heat transport problems (e.g., subsurface flow and seepage problems, unsaturated-saturated flow, advective-diffusion transport, saltwater intrusion, geothermal and thermohaline flow).

On 21 August 2010, Ontario, Canada, had its first confirmed case of the "superbug" in Brampton. There were other confirmed cases in British Columbia and Alberta. These confirmed NDM-1 infected cases have no relationship with New Delhi, India. The patients or their relatives never travelled to India in the last decade. On 6 September 2010, Japan detected its first ever case of the NDM-1 enzyme. In May 2009, a Japanese man in his 50s who had recently returned from vacation in India was struck with a fever and hospitalized, later making a full recovery. Hospital officials confirmed that tests carried out after the patient's recovery were positive for the NDM-1 enzyme. An environmental point prevalence study conducted between 26 September and 10 October 2010 found bacteria with the NDM-1 gene in drinking water and seepage samples in New Delhi.

Ongoing culvert function without failure depends on proper design and engineering considerations being given to load, hydraulic flow, surrounding soil analysis, backfill and bedding compaction, and erosion protection. Improperly designed backfill support around culverts can result in material collapse or failure from inadequate load support. For existing culverts which have experienced degradation, loss of structural integrity or need to meet new codes or standards, rehabilitation using a reline pipe may be preferred versus replacement. Sizing of a reline culvert uses the same hydraulic flow design criteria as that of a new culvert however as the reline culvert is meant to be inserted into an existing culvert or host pipe, reline installation requires the grouting of the annular space between the host pipe and the surface of reline pipe (typically using a low compression strength grout) so as to prevent or reduce seepage and soil migration.

The Kettles are two pools that are the end result of catastrophic subsidence in 1179: the Permian rocks underlying the area include substantial thicknesses of evaporites--gypsum and gypsiferous mudstone--and subsidence resulting from subterranean dissolution of these beds is a frequent occurrence, though the scale of the Hell Kettles subsidence is exceptional. Surface runoff and seepage from calcareous springs has created the two pools, one of which is the only body of spring-fed open water in County Durham: there were originally four subsidence depressions, but one filled in and two are now linked in a pond aptly named 'Double Kettle'. The name "hell-kettle" is often applied to ponds that are popularly believed to be bottomless; these particular ponds are mentioned in Holinshed's Chronicles: and, it has been suggested, may have inspired the scene in Lewis Carroll's Alice's Adventures in Wonderland in which Alice tumbles down a rabbit hole.

On 14 February 2018 Labor voted with the Greens to disallow a mechanism in the Murray Darling Basin Plan which would have prevented farmers in the Northern Basin giving up 70GL of water which otherwise would have been lost to seepage and evaporation. The disallowance motion triggered a crisis in basin states when New South Wales and Victoria pledged to abandon the Plan as a result. It was widely considered the withdrawal of the two largest states would see the Basin Plan dismantled after it had taken more than a century to strike the agreement. On 7 May 2018, in the lead up to a second disallowance motion that would have blocked 36 environmental water savings projects, Littleproud struck a deal with Labor that both secured the works in question and the 70GL recovery reduction for Northern Basin farmers which had previously been disallowed.

The MWD responded by stating that local claims had been settled and that a substantial amount of the water was being used for local agriculture, indirectly citing the Poorman contract. On June 21, 1944, the Water and Natural Resources Committee of the Hemet Valley Chamber of Commerce called a meeting of concerned ranchers from Hemet, San Jacinto, Perris, Lakeview and Nuevo. They organized themselves as the San Jacinto River Protective Committee, with Irwin Farrar elected as chairman. The committee focused on development of the local area, and claimed that water that was being carried out of the area by the MWD could irrigate up to 4,000 acres (16 km2) each year. The committee made two demands of the MWD: stop seepage in the San Jacinto tunnel, and return the estimated 150,000 acre feet (190,000,000 m3) of water than had been carried away since 1934.

Each of the main tunnel interiors was that of a windowless open- plan office constructed as a building shell within the granite void, complete with a pitched roof to collect water seepage from the rocks, a false ceiling, plastered and decorated walls and all the necessary services. In total about 15,000 tons of rock were removed to construct the tunnels. The construction work progressed relentlessly day and night, taking nearly a year and the completed tunnels were opened in May 1941 by Lady Wilshaw who was the wife of Sir Edward Wilshaw, Chairman of Cable and Wireless at the time.Bell; p 1, p 29Bell; p 5 The concrete defences around the tunnel entrances and the nearby buildings were camouflaged with the help of a local artist, the design, when viewed from the air with some imagination, resembling a belt of trees, complete with rabbits and birds.

Abney Park was included on the Heritage at Risk Register in 2009, as one of Britain's historic parks and gardens at risk from neglect and decay.English Heritage's "At Risk" register accessed 5 July 2010. Although the level of malicious damage is kept low by the conspicuous presence of staff and volunteers of the Abney Park Trust when maintaining the park; by frequent arts and environmental events promoted by the trust; and by community safety initiatives involving the police and their community support officers; nevertheless, over time it has taken its toll, leading to the current 'at risk' designation. The roof slates and roof flashings of the Abney Park Chapel have been damaged by unauthorised climbing and theft at times when the park was left unsupervised and unlocked overnight, and this has resulted in water seepage into the chapel walls which is now causing serious problems to the whole building.

Plaque of Satyamoorthi reservoir An agreement was signed jointly by Governments of Maharashtra, Karnataka and Andhra Pradesh on 14 April 1976 to spare 15 thousand million cubic feet (TMC) of Krishna water to Chennai city. Following this, an accord between Andhra Pradesh Government and Tamil Nadu Government was signed for Telugu Ganga project on 18 April 1983 for drawing 15 TMC of Krishna water to Chennai City from Sri Sailam Reservoir to be conveyed through Somaseela and Kandaleru Reservoirs and ultimately a net quantity of 12 TMC (after loss of 3 TMC en route in evaporation and seepage) will reach the Tamil Nadu border. Initial works for supplying water under this scheme were completed in 1996 and from September 1996, water is received at Poondi Reservoir from Kandaleru Reservoir in Andhra Pradesh through 152 km. long open canal up to Tamil Nadu Border near Uthukottai.

The industry declined in the late 19th century when large-scale production of potash from mineral salts was established in Germany. In 1943, potash was discovered in Saskatchewan, Canada, in the process of drilling for oil. Active exploration began in 1951. In 1958, the Potash Company of America became the first potash producer in Canada with the commissioning of an underground potash mine at Patience Lake; however, due to water seepage in its shaft, production stopped late in 1959 but following extensive grouting and repairs, resumed in 1965. The underground mine was flooded in 1987 and was reactivated for commercial production as a solution mine in 1989. A postcard of the Kalium Chemicals plant in Belle Plaine, Saskatchewan In 1964 a Canadian company known as Kalium Chemicals established the first potash mine that took advantage of the solution process. The discovery was made during oil reserve exploration.

Construction of the plant began in 1999 and was expected to be completed in 2004. Delays in construction (some for political reasons) have increased the cost of the project. Costs have also increased from increases in the costs of raw materials from 2003. The 921 earthquake in 1999 prompted three legislators to inspect construction progress; they cited rusty rebar and potential seawater seepage into the plant's foundation as potential issues. President Chen Shui-bian was elected along with other Democratic Progressive Party (DPP) legislators in March 2000 on an anti-nuclear platform which included stopping plant construction. DPP legislators called for a halt to the project in April 2000, which led to the suspension of construction in October 2000 by Premier Chang Chun-hsiung. Contractors were idled for 111 days from 2000 October 27 to 14 February 2001. This delay caused a 576-day delay towards commercial operation.

In this way, the mere is replenished by seepage from the bed of the lime-rich river, through the river's natural levée, or by winter floods. The water of the mere is then static through the summer, when the concentration of the calcium carbonate rises until it is precipitated on the bed of the mere. Even quite shallow lake water can develop a thermocline in the short term but where there is a moderately windy climate, the circulation caused by wind drift is sufficient to break this up. (The surface is blown down-wind in a seiche and a return current passes either near the bottom or just above the thermocline if that is present at a sufficient depth.) This means that the bed of the shallow mere is aerated and bottom-feeding fish and wildfowl can survive, providing a livelihood for people around.

In 1991 most of the Malibu land grant was incorporated as a city to allow local control of the area (as cities under California law, they are not subject to the same level of county government oversight). Prior to achieving municipal status, the local residents had fought several county-proposed developments, including an offshore freeway, a nuclear power plant, and several plans to replace septic tanks with sewer lines to protect the ocean from seepage that pollutes the marine environment. The incorporation drive gained impetus in 1986, when the Los Angeles County Board of Supervisors approved plans for a regional sewer that would have been large enough to serve 400,000 people in the western Santa Monica Mountains. Residents were incensed that they would be assessed taxes and fees to pay for the sewer project, and feared that the Pacific Coast Highway would need to be widened into a freeway to accommodate growth that they did not want.

In 1988, the 6.9-liter engine was supplanted by the 7.3-liter upgrade, with over 300,000 6.9's shipped to Ford and countless numbers installed into medium-duty trucks, school buses, and the like. This engine features numerous improvements over the 6.9-liter, with most of the changes located in the heads; the block received an increase bore and select-fit pistons, while the heads received an enlarged prechamber, enlarged valve stem shields, harder valves, and other minor upgrades. The front cover was revised to reduce seepage. The 1st 7.3-liter engine was introduced in 1986 for the International s-series trucks & school buses, The 6.9-liter and the 7.3-liter engine was an optional for International s-series trucks and school buses from 1986-1987 before it went straight to the 7.3-liter engine in 1988 for Ford trucks and International trucks and school buses until the end of the 1994 year model.

Casagrande's passionate interests in earth dams can be seen in the extensive research work he has carried out on seepage as well as soil liquefaction. It was also through the study commissioned by the Corps of Engineers (who after WWII became concerned about the influence of a possible atomic blast on the stability of embankments of the Panama Canal) that led Casagrande to become one of the first persons in the world to investigate the dynamic strength of soils. Even though the word "liquefaction" was first used by Casagrande in the soil mechanics literature, he considered it to be inappropriate for describing the effects of earthquake loading or cyclic loading in building up pore pressures and deformations in sands (which is effectively the modern notion of liquefaction). Casagrande strenuously insisted that the definition of liquefaction should be reserved for soil exhibiting drastic strain-softening which results in an almost flow- type behavior.

The pits were a source of gault, an impervious clay used to maintain river banks in the low- lying regions of the South Level of the Fens. Following the re-routing of the rivers in the region by Cornelius Vermuyden and his Adventurers in the 1650s, to more effectively drain the Fens, the peaty soils began to dry out and shrink.The Urgent Hour, (1983), John Beckett, Ely Local History Publication Board, As the land surface sunk below the levels of the rivers, it became important to maintain the banks with something impervious to water, to prevent seepage into the newly drained agricultural land, and to prevent collapse of the banks and flooding of the land in times of heavy rainfall. Roswell Pits were an ideal source of this material, as they were located adjacent to the River Great Ouse, and boats could take the bulky material directly to the banks being maintained.

Flooded streets in New Orleans Relationship between impervious surfaces and surface runoff Urban runoff is a major cause of urban flooding, the inundation of land or property in a built-up environment caused by rainfall overwhelming the capacity of drainage systems, such as storm sewers. Triggered by events such as flash flooding, storm surges, overbank flooding, or snow melt, urban flooding is characterized by its repetitive, costly and systemic impacts on communities, regardless of whether or not these communities are located within formally designated floodplains or near any body of water.Center for Neighborhood Technology, Chicago IL "The Prevalence and Cost of Urban Flooding." May 2013 There are several ways in which stormwater enters properties: backup through sewer pipes, toilets and sinks into buildings; seepage through building walls and floors; the accumulation of water on property and in public rights-of-way; and the overflow of water from water bodies such as rivers and lakes.

By the 1980s, the building suffered from water seepage, cracked plaster and badly outdated electrical, plumbing and HVAC systems. The newly restored building is a point of pride on campus, both for its beauty and the sense of history it affords, according to NIU President John Peters. “The restoration of Altgeld Hall was an important step for NIU. It is a physical connection with our very roots as a university and we are proud to see the project recognized by the construction industry.” said Peters. “Altgeld Hall is not a museum, but a living, working public space where the roots of American higher education are still very much in view.” Currently, Altgeld Hall houses the Office of the President, Academic and Student Affairs, Finance and Facilities, University Advancement & NIU Foundation, University Legal Services, University Council, Community and External Affairs, the NIU Art Museum, the Instructional Technology Teaching Laboratory, conference rooms, and an auditorium with seating capacity for 500.

A metal fence was erected to block off the fountain again in 2018 and replaced with a white plastic fence by April 2019; that was replaced with a high plywood fence in August in preparation for a project to convert part of the fountain's sump into a storage tank for treated non-potable water that will be used to wash streets in Civic Center and the Tenderloin. A branch of the subterranean Hayes Creek had been discovered to run underneath UN Plaza during the construction of the fountain's sump; seepage had been pumped for use in street-cleaning trucks, but that source was abandoned in the 1980s. Three proposals were advanced in 2018 to redesign the entire Civic Center area, including UN Plaza; of those three, only Civic Sanctuary calls for the restoration of the fountain at UN Plaza. Public Platform would install a new "iconic, interactive fountain" near the present site.

With continuing experience, particularly on the upper continental slope in the Gulf of Mexico, the successful prediction of the presence of tubeworm communities continues to improve, however chemosynthetic communities cannot be reliably detected directly using geophysical techniques. Hydrocarbon seeps that allow chemosynthetic communities to exist do modify the geological characteristics in ways that can be remotely detected, but the time scales of co-occurring active seepage and the presence of living communities is always uncertain. These known sediment modifications include (1) precipitation of authigenic carbonate in the form of micronodules, nodules, or rock masses; (2) formation of gas hydrates; (3) modification of sediment composition through concentration of hard chemosynthetic organism remains (such as shell fragments and layers); (4) formation of interstitial gas bubbles or hydrocarbons; and (5) formation of depressions or pockmarks by gas expulsion. These features give rise to acoustic effects such as wipeout zones (no echoes), hard bottoms (strongly reflective echoes), bright spots (reflection enhanced layers), or reverberant layers (Behrens, 1988; Roberts and Neurauter, 1990).

Exterior of the 1981 building Iconic letters outside of building In 1981, the growth of the library required a new building, which was built just across the street at 2880 Hennepin Avenue South. The two main floors of the building were underground. There was a large "LIBRARY" sign on Hennepin Avenue with an entry pavilion to indicate the presence of the library. Although the library was built underground to conserve space and save energy, the underground building was not very visible, and had problems with water seepage. By 2006, proposals were being considered to replace the library with something that would be more visible. In the 1970s the Walker Library at 2901 Hennepin Avenue was deemed, “not to meet the standards of a modern facility…with many exterior steps and the interior is crowded.” It was replaced by Walker Community Library, 2880 Hennepin Avenue South in 1981, which was built out of concrete and earth at a cost of $2.3 million. It was designed by Myers & Bennett and built by George F. Cook Construction.

Beneath the great domed Katholikon is a burial crypt, accessible only by a stairwell on the southern side. The crypt has three distinct areas: the entrance way; the main interior space which includes nine groin-vaulted bays and a sanctuary with a vaulted bay and an apse; and three vaulted passages, referred to formerly as bone vaults. The crypt’s frescoes were until recently covered in hundreds of years of dust and hidden but in the 1960s the crypt underwent a cleaning by the Greek Archaeological Service which revealed their remarkably well preserved state with the exceptions of the apse which has lost most of its plaster exposing brick and stone, as well as the entrance vault and groin vaults which have suffered slight damage from water seepage and minor vandalism, mostly on the lower lunettes near the entrance. The crypt contains frescoes on the entryway and its vault, eight lunettes around the walls with depictions of Christ’s Passion and Resurrection, and forty medallion portraits of apostles, martyrs and holy men, abbots including Philotheos, as well as numerous inscriptions.

The oilfield-related subsidence in the Inglewood field, though generally denied by the oil companies as a legal policy, was documented exhaustively by the US Geological Survey in 1969.Castle 1969 Subsidence following oil extraction from shallow deposits in unconsolidated sediments had been understood by oil industry experts since the 1920s.Geertsma 1973 Following the discovery in 1970 by geologist Douglas Hamilton of faulting and surface seepage of oilfield waste brines along the fault, which traversed and extended south of the reservoir, Hamilton and Meehan concluded that oilfield injection for waste disposal and improved recovery of oil, a new technology at the time, was a significant cause of the failure, triggering hydraulic fracturing and aggravating movements on a fault traversing the reservoir even on the day of the failure.Hamilton 1971 Subsequently, the US Geological Survey concluded in 1976 that displacements at the ground surface causing reservoir failure and ground cracking in the Stocker-LaBrea area southeast of the reservoir were 90% or more attributable to exploitation of the Inglewood oil field, and that this faulting was likely aggravated by water flooding with pressures exceeding hydraulic fracturing levels.

In 1932, Casagrande moved to Harvard University where he would later be promoted to a newly created chair of soil mechanics and foundation engineering in 1946. There he rapidly established a school of postgraduate teaching and research that would see the number of students steadily grow from 12 in 1932 to over 80 after World War II. At one stage during 1942–44, Casagrande went on to train a total of approximately 400 army officers on the soil mechanics aspects of airfield construction through a series of intensive four-week programmes at the request of the Army Corps of Engineers. Even though Terzaghi would later join Harvard (with the assistance of Casagrande) from Vienna out of concerns on the turbulent political landscape in Europe, Casagrande was effectively alone in the soil mechanics section because of Terzaghi's many periods of absence (Terzaghi would often be away to the University of Illinois collaborating with his close friend Ralph Peck) and disdain of administrative duties. The successful soil mechanics and foundation engineering programme at Harvard was hence often credited to Casagrande, and its particular emphasis on laboratory courses and seepage being an integral part of the curriculum would later form the basis of similar courses around the world.
