Canada has a number of canals, including some ship canals. Most are located in eastern Canada, namely in Ontario, Quebec, and three in Nova Scotia. Seton Canal is located in British Columbia and is mostly a diversion channel.

Canals can disrupt water circulation in marsh systems. Large-scale ship canals such as the Panama Canal and Suez Canal continue to operate for cargo transportation, as do European barge canals. Due to globalization, they are becoming increasingly important, resulting in expansion projects such as the Panama Canal expansion project. The expanded canal began commercial operation on 26 June 2016.

The horizontal loop radiated most of its energy in the form of a surface wave, thereby minimising any unwanted interference. In practical terms, erecting a horizontal loop antenna on a ship caused several problems. The loop was supported by guy wires from a central mast. It was too wide for the ship to pass through Dutch ship canals, so the side sections had to be hinged so they could be raised to a vertical position until the ship was at sea.

In 1875, Thornton would return to his first and favorite love - in the realm of economics - with land tenure systems heading the fray of his arguments. Accompanying his newest arguments were irrigation and multiple "artifacts" of "bureaucratic levers of control and economic development". The final work was a book titled Indian Public Works and Cognate Indian Topics. The book also covered India's controversies over the railroad development across the country, the ship canals, and telegraph wires that ranged from cities to cities.

In 1885–1886, he edited the American Engineering Register. In 1897, President William McKinley appointed him to the Nicaraguan Canal Commission, which studied the possibility of a canal connecting the Atlantic and Pacific Oceans. A route through Panama was finally selected, and Haupt was appointed to the Panama Canal Commission. He was president of the Colombia-Canea Arbitration (1897), and was chief engineer of the survey for ship canals across New Jersey, and was consulting engineer on the construction of the Ohio-Lake Erie ship canal.

Carlisle & Finch Company.Carlisle & Finch Company. It is an active navigational aid and is known as the South Breakwater Light by the United States Coast Guard in the Volume VII light list and the United States Geological Survey Geographic Names Information System. It is located on the southern Superior Harbor entry breakwall. The Saint Louis River, which rises in Minnesota, becomes the Saint Louis Bay, then flows into Superior Bay and exits into Lake Superior via the ship canals, at each end of (Park Point) Minnesota Point.

Total length of waterways per country in kilometers This is a list of waterways, defined as navigable rivers, canals, estuaries, lakes, or firths. In practice, and depending on the language, the term "waterway" covers maritime or inland transport routes, as suggested by "way". Wherever a free- flowing river cannot bear load-carrying vessels, the correct term is "watercourse", with no connotation of use for transportation of cargo. To be of practical use, the list distinguishes international maritime waterways (including ship canals), international inland waterways, then inland waterways, including canals and large lakes.

On large modern canals, especially very large ones such as ship canals, the gates and paddles are too large to be hand operated, and are operated by hydraulic or electrical equipment. On the Caledonian Canal the lock gates were operated by man-powered capstans, one connected by chains to open the gate and another to draw it closed. By 1968 these had been replaced by hydraulic power acting through steel rams. Even on smaller canals, some gates and paddles are electrically operated, particularly if the lock is regularly staffed by professional lock keepers.

The forerunner to the first Welland Canal was the watercourse of the Twelve Mile Creek which enabled sailing ships to travel and be pulled by horses up the watercourse to the heart of the city. Subsequently, this early navigational course was developed into a canal and preceded three ship canals that followed a path through the city until the present-day fourth ship canal. The cornucopia, commonly referred to as a "horn of plenty", pertains to the rich agriculture and fruitlands abundant in the area. The millstone, (sometimes, and incorrectly, referred to as a grindstone) is symbolic of the grist mills and flour mills prevalent of an earlier era.

Mercer gave English names to two large Seattle lakes previously known by their Native American names. In an address delivered at Seattle's first Fourth of July picnic in 1854 he suggested that the greater be called Lake Washington after George Washington in recognition of the occasion, to replace the Duwamish tribe's Lushootseed language name, Xacuabš ("great- amount-of-water"). The smaller lake, XáXu7cHoo ("small great-amount-of-water") in Lushootseed, Mercer renamed to Lake Union. This was the first vague proposal for the union of Lake Washington with Puget Sound via ship canals, eventually realized decades later in the form of the Lake Washington Ship Canal.

The first survey of Lake Superior was undertaken in 1823 by Henry W. Bayfield of the British Navy, who chose a spot on Minnesota Point as the zero point of his mapping. The point is the eastern end of a great sand bar separating Superior Bay from the lake; the passage to the east of the point (known as Superior Entry) was the original outlet of the Saint Louis River. The Saint Louis River, which rises in Minnesota, becomes the Saint Louis Bay, then flows into Superior Bay and exits into Lake Superior via the ship canals, at each end of Minnesota Point (Park Point). Both Superior, Wisconsin, and Duluth, Minnesota, sprang up on opposite banks of the river and bay to take advantage of the excellent natural harbor; thus plans for a lighthouse to mark the entrance preceded Minnesota statehood, and appropriation was made by Congress in 1855.

For the movement of bulk raw materials such as coal and ores are difficult and marginally affordable without water transport. Such raw materials fueled the industrial developments and new metallurgy resulting of the spiral of increasing mechanization during 17th–20th century, leading to new research disciplines, new industries and economies of scale, raising the standard of living for any industrialized society. The surviving canals including most ship canals, today primarily service mostly bulk cargo and large ship transportation industries, whereas the once critical smaller inland waterways conceived and engineered as boat and barge canals have largely been supplanted and filled in, abandoned and left to deteriorate, or kept in service and staffed by state employees, where dams and locks are maintained for flood control or pleasure boating. Their replacement was gradual, beginning first in the United States in the mid-1850s where canal shipping was first augmented by, then began being replaced by using much faster, less geographically constrained & limited, and generally cheaper to maintain railways.

During heavy periods of rain or when the Des Plaines overflowed its banks due to downstream ice dams in the early spring, the river would flow through Mud Lake to the South Branch of the Chicago River, forming a favorite portage for early traders and creating the path of the future I&M; and Chicago Sanitary and Ship Canals. When the city we know today was initially founded in the 1830s, the land was swampy and most of the early building began on low dunes around the Chicago River's mouth. Indeed, Chicago's low lying geography, which ultimately became crucial to its boom town development (as the site of the Chicago Portage and canal), could not initially attract substantial early settlement because the tall grass prairie around its lake and river systems was underlain by hard packed glacial clay, making much of the area forbidding wetlands.Donald L. Miller, City of the Century, p.

Towing path and canal bed of the Portsmouth and Arundel Canal near Woodgate, Sussex The Portsmouth and Arundel Canal was a canal in the south of England that ran between Portsmouth and Arundel, it was built in 1823 but was never a financial success and was abandoned in 1855; the company was wound up in 1888. The canal was part of a larger scheme for the construction of a secure inland canal route from London to Portsmouth, which allowed craft to move between the two without having to venture into the English Channel and possibly encounter enemy ships or natural disaster. It was built by the Portsmouth & Arundel Navigation company. The canal was made up of three sections: a pair of ship canals, one on Portsea Island and one to Chichester, and a barge canal that ran from Ford on the River Arun to Hunston where it joined the Chichester section of the canal.
