As Cologne Bay (rarely Cologne-Bonn Bay ) which is low terraces - level of the Rhine , made up, of Bonn in the southeast northwestward over Cologne until immediately before Dusseldorf and Neuss draws.

It is located in the southwest of North Rhine-Westphalia and forms the central part of the Lower Rhine Bay , which sinks into the Rhenish Slate Mountains from the northwest . To the east and west of the Cologne Bay, the adjoining partial landscapes of the Lower Rhine Bay rise in terraces towards the Southern Mountains (in the east) and the Eifel (in the west).

Occasionally the term Cologne Bay is used synonymously with the entire Lower Rhine Bay or the agglomeration of the city of Cologne.

geography

Location and limits

The Cologne Bay is framed by the wider landscapes of the Lower Rhine Bay. The border is particularly clear on the west side with the bounding landscape of the Ville and its eastern slope, the promontory . On the east side, the area of ​​the surrounding heather terraces does not rise so clearly, but the change to the heather is particularly noticeable. To the northwest, the entire bay opens up along the Rhine and merges into the Lower Rhine Lowland , to which the Münsterland chalk basin of the Westphalian Bight sinks from the east . Further to the northwest, the Rhine and Maas valleys gradually merge.

Natural structure

In terms of nature , the Cologne Bay represents a main unit (three-digit) and is divided into sub-units (decimal places ) as follows:

The Lower Rhine Bay (55) with the Cologne Bay (551) in the center
Dormagener Rheinaue near Zons
  • 55 (to 55 Lower Rhine Bay )
    • 551 Cologne Bay in the narrower sense ( Cologne-Bonn-Rhine plain and central terrace slabs on the left bank of the Rhine )

Culture

Due to the function of the Rhine as a mode of transport since ancient times, the bay is heavily populated and shaped by people. In recent times this traffic situation has also been used by industry, particularly in the peripheral areas of the agglomerations .

climate

As the southernmost foothills of the Lower Rhine lowlands, the Cologne Bay, protected by the surrounding mountains, is one of the warmest regions in Germany with average annual temperatures between 10 and 11 ° C.

The maritime climate is influenced by the Gulf Stream across the Atlantic and the proximity to the North Sea. Mild winters and moderate summers correspond to this situation.

In turn, the bay location can lead to inversion weather situations in which there is hardly any air exchange and pollutant concentrations in the air rise.

Geological history of development

About 30 million years ago parts of the Rhenish Slate Mountains sank, and a lowland area formed, which the Rhine alternately accumulated or carried away with gravel. The imprint of the immediate Cologne Bay, the lower terrace, took place in the geologically most recent era. Often, former rivers can still be seen on it, for example the Worringer Bruch . The arable land is characterized by the alternation of gravelly areas with more fertile stretches of alluvial clay.
