Niederrhein
Upper Rhine
Area situated along the German-Dutch border
The sub-area is located at the Lower Rhine along the German-Dutch border. The whole region is characterized by agriculture. The most important tributaries of the Lower Rhine are the Ruhr and the Lippe. Like the Upper Rhine, also the Lower Rhine is straightened and large sections of the riverbanks are reinforced by rock fills. Moreover, groynes have altered the course of the stream and have lead to vertical erosion. The narrowing of the floodplains by dams has significantly affected the river ecosystem. Only minor sections of the Lower Rhine are still in their natural state. The surroundings are characterized by pastures and grazing land for cattle and sheep.
