Merwede in the context of "Hollands Diep"

The Nieuwe Merwede (Dutch pronunciation: [ˌniu.ə ˈmɛrʋeːdə]; "New Merwede") is a Dutch canal, mainly fed by the river Rhine, that was constructed in 1870 to form a branch in the Rhine–Meuse delta. It was dug along the general trajectories of a number of minor Biesbosch creeks to reduce the risk of flooding by diverting the water away from the Beneden Merwede, and to facilitate navigation and regulate river traffic in the increasingly silted-up delta.

It is one of several rivers called Merwede. The most upstream is the river Boven Merwede ("Upper Merwede"), itself the continuation of the Rhine-Waal river and, until 1904, the Meuse (now the closed-off Afgedamde Maas) as well. The Boven Merwede branches near the town of Hardinxveld-Giessendam into River Beneden Merwede ("Lower Merwede") to the northwest and the Nieuwe Merwede to the southwest. The Nieuwe Merwede joins River Bergse Maas near Lage Zwaluwe to form the Hollands Diep estuary, and separates the Island of Dordrecht from the Biesbosch National Park.

The Boven Merwede (Dutch pronunciation: [ˌboːvə ˈmɛrʋeːdə]; "Upper Merwede") is a stretch of river in the Netherlands, mainly fed by the river Rhine. The Afgedamde Maas river joins the Waal at Woudrichem to form the Boven Merwede, which at Hardinxveld-Giessendam splits into the Beneden Merwede river on the right and the Nieuwe Merwede river on the left. Its length is 8.8 km (5.5 mi). The Merwede is part of the main shipping route between Rotterdam and Germany.

A road bridge connects the west side of Gorinchem on the north to the west side of Sleeuwijk on the south.

The Afgedamde Maas (Dutch pronunciation: [ˌɑfxədɑmdə ˈmaːs]; Dammed-up Meuse) is a former distributary of the Maas River (French: Meuse) in the Dutch provinces of North Brabant and Gelderland. The Maas splits near Heusden with one channel flowing north until its confluence with the river Waal (the main distributary of the river Rhine) to form the Merwede, while the other channel (the Bergse Maas) continues west as the main distributary of the Maas.

The Bergsche Maas (Dutch pronunciation: [ˈbɛr(ə)xsə ˈmaːs]; current spelling: Bergsche Maas) is a canal that was constructed in 1904 to be a branch of the river Maas (French: Meuse) in the Dutch province of North Brabant. The Maas splits near Heusden into the Afgedamde Maas and the Bergse Maas. The Afgedamde Maas flows north until its confluence with the river Waal (the main distributary of the river Rhine) to form the Merwede, while the Bergse Maas continues west as the main distributary of the Maas. Part of the Merwede (the Nieuwe Merwede) rejoins the Bergse Maas to form the Hollands Diep estuary.
