The 'Dender' (-Dutch, in French: 'Dendre') is a 65 km long river in
Belgium, right tributary of the river
Scheldt. The confluence of both rivers is in the Belgian town
Dendermonde.
The Western or Little Dender springs near
Leuze-en-Hainaut at altitude of about 60 to 70 meters above sea level. The source of the Eastern Dender is near
Jurbise at a height of 100 meters above sea level. The two rivers meet in the town of
Ath. The length of the Western Dender up to Ath is 22 kilometers, the Eastern Dender is 39 km long. From that confluence the river is called the Dender proper. From Ath, the river passes through the cities and towns of
Geraardsbergen,
Ninove,
Denderleeuw and
Aalst to end in
Dendermonde. The Dender is navigable for small ships up to 300 ton.
