The Nieuwe Merwede ("New Merwede") is a canal that was constructed in 1870 to form a branch in the Rhine-Meusedelta. It was dug along the general trajectories of a number of minor Biesbosch creeks to facilitate navigation and regulate river traffic in the increasingly silted-up delta.
The Boven Merwede is a stretch of river in the Netherlands.
The Afgedamde Maas river joins the Waal at Woudrichem to form the Boven Merwede, which at Hardinxveld-Giessendam splits into the Beneden Merwederiver on the right and the NieuweMerwederiver on the left.
There is a road bridge, from the west side of Gorinchem on the north to the west side of Sleeuwijk on the south.
River Boven Merwede ("Upper Merwede"), itself the continuation of the Rhine-Lek and Meuserivers after their confluence at Gorinchem, branches near the town of Hardinxveld-Giessendam into River Beneden Merwede ("Nether Merwede") to the northwest and the NieuweMerwede to the southwest.
The NieuweMerwede joins RiverBergse Maas near Lage Zwaluwe to form the Hollands Diep estuary, and separates the Island of Dordrecht from the Biesbosch National Park.
There are no bridges or tunnels crossing the NieuweMerwede, but there is a car ferry from the Island of Dordrecht on the west at "Kop van 't Land" to Brabantse Oever, Werkendam (Biesbosch).
