List of rivers in North Rhine-Westphalia

The list of rivers in North Rhine-Westphalia contains a selection of the rivers that are wholly or partly in North Rhine-Westphalia (NRW). The waters are grouped according to the major river systems Rhine , Maas , Weser and Ems , whereby the Meuse belongs to the river system of the Rhine , which is also expressed in the river code (Rhine: 2, Maas: 28), but with the river basin units that defined for administrative purposes (including the coastal fringes) is shown separately. Furthermore, they are partly divided into further sub-areas within these areas. The list does not contain all of the named rivers in North Rhine-Westphalia, but at least all rivers with a total length of 30 kilometers or more that are wholly or partially located in North Rhine-Westphalia. In order to generate a hierarchical representation, rivers are also included that run entirely outside of North Rhine-Westphalia, but in turn contain listed North Rhine-Westphalia rivers.
All river systems in North Rhine-Westphalia are linked by natural flowing waters via the Rhine-Maas Delta , the bifurcations of the Schwarzwasserbach from the Krollbach and the bifurcations of the Else from the Hase . North Rhine-Westphalia is completely drained to the North Sea. The hard coal mining in the Ruhr area led to subsidence and large polder areas , which can only be kept artificially dry by constant hydraulic engineering measures; Without human intervention, large parts of the Ruhr area would be under water.
Systematics
System: name of the water body (length (thereof in NRW), catchment area (thereof in NRW), L / R)
- Length in kilometers
- Catchment area in km²
- L / R: Left or right inflow
All tributaries are ordered downstream in relation to the respective main river. The tributaries are indented according to their order in the river system:
- 1st order (river flows into the sea)
- 2nd order (river flows into a river that flows into the sea)
- 3rd order (river flows into a river that flows into a river that flows into the sea)
- 4th order: analogous, see above
- 3rd order (river flows into a river that flows into a river that flows into the sea)
- 2nd order (river flows into a river that flows into the sea)
All rivers whose course does not lie entirely within the NRW area are listed in italics .
Rhine → North Sea
Note: The Rhine has a total length of 1,233 kilometers. Of these, 226 kilometers are in North Rhine-Westphalia in the sections Middle Rhine, Lower Rhine and Delta Rhine. In the Delta Rhine, the lengths of the side arms are not included. Without the IJsselmeer tributaries (in the delta only the direct catchment area of the Waal and Nederrijn / Lek), the Rhine has a catchment area of 163,141 square kilometers. Of these, around 18,847 km² are in North Rhine-Westphalia. With the previously excluded rivers, the Rhine has a catchment area of around 185,300 km². The IJsselmeer tributaries have a total catchment area of around 10,010 km². Of these, about 2185 km² are in NRW.

The river systems of the Rhine and the Ems are connected by the bifurcation of the Schwarzwasserbach from the Krollbach .
Rhine delta
Note: In the Rhine delta, the rivers are no longer to be ordered strictly hierarchically. Rather, it is about tributaries of the Rhine or other rivers, or the lower reaches of other rivers, which are often connected to one another by canals or side arms that have been developed into canals with the direction of flow depending on the water level. The IJssel, for example, is a northern branch of the Rhine estuary. Therefore, depending on the definition, the catchment area of the rivers is not uniform. The Maas river system flows into the Rhine-Maas delta in the river system of the Rhine, about 40 kilometers before reaching the North Sea.
