The Deûle ( Dutch Deule ) is a river in northern France , in the Hauts-de-France region . It crosses the Pas-de-Calais and Nord departments .

geography

The Deûle at Quesnoy-sur-Deûle

Its two source streams, Saint-Nazaire and Clarency, unite in the village of Souchez to form the Souchez river , which is known as the upper reaches of the Deûle and which merges into the Canal de Lens after a few kilometers in Lens . This canal is a branch canal and flows at Courrières into the canalized Deûle (also: Canal de la Deûle ) from here on . Under this name, it then flows through Lille and to its confluence in Deûlémont ( Deulemonde in Dutch ), on the Belgian- French border. There it flows as a right tributary into the Leie ( French Lys ), a tributary of the Scheldt .

shipping

Almost its entire length of the river is canalised for shipping, only its upper course still flows under natural conditions.

The canalized Deûle includes the following sections:

  • Section between Douai and Bauvin , length 26 km, 1 lock
    It overcomes the ridge between the valleys of the Scarpe and Deûle and is part of the major shipping route Dunkirk-Scheldt , which continues to the west in the Canal d'Aire .
  • Canal de Lens canal (German: Lens Canal ), length 8.5 km
    This branches off in Courrières and provides a connection to the city of Lens. It also takes care of the water supply from the upper reaches of the Deûle.
  • Distance between Bauvin and Marquette-lez-Lille 23 km long, 2 locks
    It connects to Lille and the Canal de Roubaix , which joins Marquette-lez-Lille.
  • Branch Canal Canal de Seclin (German: Seclin Canal ), length 4.5 km
    This branches off at Wavrin and provides a connection to the city of Seclin .
  • Basse-Deûle (German: Untere Deûle ), length 11 km, 1 lock
    It extends from Marquette-lez-Lille to its confluence with the Leie at Deûlémont.

The canalised Deûle has been continuously navigable for category IV ships with a loading capacity of 1350 tons ( European ship ) since 2004 . The exception to this are the branch channels, which remained in the Freycinet format but are hardly used today. The section of the large shipping route Dunkirk-Scheldt is navigable with ships up to a loading capacity of 3000 tons.

history

The Deûle has been canalized since the Middle Ages. Already in the 17th century there was a connection with the Scarpe near Douai. In the 19th century, Lille became the center of a network of waterways for Penichen, with canals and canalized rivers to Belgium , Calais , Douai, and especially Dunkirk . It was not until the end of the 20th century that the Deûle began to be expanded in such a way that traffic with European ships from Belgium via the Leie to northern France is possible.
