Canal De La Somme
The Canal de la Somme is a canal in northern France. Its total length is 156.4 km with 25 locks, from the English Channel at Saint-Valéry-sur-Somme to the Canal de Saint-Quentin at Saint-Simon. History The Somme River was canalized beginning in 1770. The 54 km section from St. Simon to Bray was completed by 1772, but the rest was not finished until 1843. Overview The canal as originally built has seen substantial modifications since construction of the Canal du Nord in 1904–1965, and is now made up of four distinct sections: * and 1 lock from Saint-Valery-sur-Somme to Abbeville (the ''Canal maritime'') * and 18 locks from Abbeville to Péronne * with 2 locks the section upgraded as part of the Canal du Nord * and 4 locks from Voyennes to Saint-Simon, closed upstream from Offoy since 2004.

Canals or artificial waterways are waterways or engineered channels built for drainage management (e.g. flood control and irrigation) or for conveyancing water transport vehicles (e.g. water taxi). They carry free, calm surface flow under atmospheric pressure, and can be thought of as artificial rivers. In most cases, a canal has a series of dams and locks that create reservoirs of low speed current flow. These reservoirs are referred to as ''slack water levels'', often just called ''levels''. A canal can be called a ''navigation canal'' when it parallels a natural river and shares part of the latter's discharges and drainage basin, and leverages its resources by building dams and locks to increase and lengthen its stretches of slack water levels while staying in its valley. A canal can cut across a drainage divide atop a ridge, generally requiring an external water source above the highest elevation. The best-known example of such a canal is the Panama Canal. Man ...
