Lower Rhine Bay

The Lower Rhine Bay[1] (German: Niederrheinische Bucht), sometimes called the Lower Rhine Bight,[2] is a lowland plain in the German state of North Rhine-Westphalia that cuts into the Rhenish Massif.

To the south, are the Lower Middle Rhine region including the Pleiser Hills, Siebengebirge and Lower Middle Rhine Valley, to the southwest is the Eifel.

To the north, the loess strip forms the boundary with the Lower Rhine Plain.

The surface of the landscape is flat or gently rolling and divided by tectonically-formed ridges and valleys that mainly run from southeast to northwest.

Characteristic of the area is the blanket of loess west of the Rhine deposited by the prevailing westerly winds from the Meuse gravels and the heathland east of the river which is covered with coarse-grained sands.
