Durdent (river) Durdent (river) The river Durdent is one of the many small coastal rivers that flow from the plateau of the Pays de Caux into the English Channel. The river rises just northwest of Yvetot, near Héricourt-en-Caux, at the meeting of the two streams, the Saint-Denis and the Saint-Riquier, then takes a north-northwest route, typical of the rivers of the Seine-Maritime department. It passes through the villages of Robertot, Sommesnil, Oherville, Le Hanouard, Clasville, Grainville-la-Teinturière, Cany-Barville, Vittefleur and Paluel and empties into the English Channel at Veulettes-sur-Mer. In earlier times, it powered many watermills along its course. The Durdent valley is
Sundays River South/Southeasterly direction, passing the town Graaff-Reinet in the Karoo before winding its way through the Zuurberg Mountains and then past Kirkwood and Addo in the fertile Sundays River Valley. It empties into the Indian Ocean at Algoa Bay after running through the village of Colchester, 40 km east of the city of Port Elizabeth. The Fish River-Sundays River Canal Scheme consists of a canal and tunnel system which supplies water from the Orange River to the Great Fish River Valley and subsequently to the Sundays River Valley in order to supplement the existing water supply of the Eastern Cape.
