The Grand Canal (Chinese: 大运河; pinyin: Dà yùnhé) is a system of interconnected canals linking various major rivers in North and East China, serving as an important waterborne transport infrastructure between the north and the south during Medieval and premodern China.
When built, the 363-mile (584 km) canal was the second-longest in the world after the Grand Canal in China. Initially 40 feet (12 m) wide and 4 feet (1.2 m) deep, the canal was expanded several times, most notably from 1905 to 1918 when the "Barge Canal" was built and over half the original route was abandoned.
The Grand Canal (Irish: An Chanáil Mhór) is the southernmost of a pair of canals that connect Dublin, in the east of Ireland, with the River Shannon in the west, via Tullamore and a number of other villages and towns, the two canals nearly encircling Dublin's inner city.
A plan and side view of a generic, empty canal lock. A lock chamber separated from the rest of the canal by an upper pair and a lower pair of mitre gates.The gates in each pair close against each other at an 18° angle to approximate an arch against the water pressure on the "upstream" side of the gates when the water level on the "downstream" side is lower.
Though all of the lakes are naturally connected as a chain, water travel between the lakes was impeded for centuries by obstacles such as Niagara Falls and the rapids of the St. Marys River. [2] Its principal civil engineering works are the Welland Canal between Lakes Ontario and Erie, and the Soo Locks between Huron and Superior.
The GRAND Canal would stabilize water levels in the Great Lakes and St. Lawrence River and improve water quality. The GRAND Canal system would also deliver new fresh water from the James Bay dyke-enclosure, via the Great Lakes, to many water deficit areas in Canada and the United States. The project was estimated in 1994 to cost C$100 billion ...
In a corner of northeast France, the ground rumbles with industry. After multiple false starts and much political back and forth, work is underway on the Seine-Nord Europe Canal (SNEC), a €5.1 ...
The canal diverts much of the water from the original bed of the fast-flowing Rhine in this area, which is almost entirely unnavigable by boats. The Grand Canal produces hydroelectric power at Kembs , Ottmarsheim , Fessenheim and Vogelgrun, supplying electricity to one of the most heavily industrialized regions in France and even to Germany .
