Dender

The Dender () or Dendre () is a long river in Belgium, the right tributary of the river Scheldt. The confluence of the two rivers is in the Belgian town of Dendermonde.

The Western or Little Dender is long and begins in Barry near Leuze-en-Hainaut at an elevation of about above sea level. It begins as several canals in the fields merging together to form the Little Dender. As such, it does not have any one specific source. The source of the Eastern Dender, which is long, is near Jurbise at a height of above sea level. The two rivers meet in the town of Ath. From that confluence, the river is called the Dender proper. From Ath, the Dender passes into the Denderstreek through the cities and towns of Geraardsbergen, south of which its tributary, the Mark, flows into it. From this confluence, the river continues to flow through Ninove, Denderleeuw, and Aalst, before ending in Dendermonde. The Dender is navigable up to Aalst for small ships up to 600 tons and further upstream for ships up to 350 tons. The Molenbeek-Ter Erpenbeek flows into the Dender at Hofstade.
