The Beneden Merwede is a stretch of river in the Netherlands, the continuation of the Boven Merwede after the branching-off of the Nieuwe Merwede ship canal. It flows from Hardinxveld-Giessendam to Dordrecht, where it splits into the Noord and Oude Maas rivers. Its length is 14.9 km. The Merwede is part of the main shipping route between Rotterdam and Germany.

There is a road bridge and, more to the east, a railroad bridge between the train stations Dordrecht Stadspolders and Hardinxveld-Giessendam on the line Dordrecht-Gorinchem.

Beneden Merwede

The Merwede (etymology uncertain, possibly derived from the ancient Dutch (Merwe or Merowe) word meaning "wide water") is the name of several interconnected stretches of river in The Netherlands, all part of the Rhine-Meuse-Scheldt delta. The Meuse river joins the Waal at Woudrichem to form the Boven Merwede (Upper Merwede). A few kilometers downstream it splits into the Beneden Merwede (Lower Merwede) on the right and the Nieuwe Merwede (New Merwede) on the left. All these rivers are tidal. The Nieuwe Merwede joins the Bergse Maas near Lage Zwaluwe to form the Hollands Diep estuary, and separates the Island of Dordrecht from the Biesbosch National Park. The Beneden Merwede splits into the Noord River and Oude Maas near Papendrecht.

In medieval times there was no such distinction. The Merwede (or "Merwe" in Middle Dutch) was the name of a continuous stretch of river, considered to be the lower part of the river Waal (being a major distributary branch of the Rhine). Although the name Merwede is currently only used between the towns of Woudrichem and Papendrecht, during its early history it carried on his name all the way to the sea - including the rivers currently named Noord river and Nieuwe Maas.
