The Godesberger Rheintaltrichter (occasionally also Bonn-Godesberger Taltrichter ) is a natural area in the south of North Rhine-Westphalia and the southernmost part of the Cologne Bay , which represents a natural spatial unit . It extends substantially over the Bonn district of Bad Godesberg and is settlement geographically the compression chamber Bonn assign.

Demarcation

In the north, the Godesberg Rhine valley funnel merges into the southern Cologne Rhine plain (also Cologne-Bonn Lower Terrace ), the Cologne-Bonn Rhine valley and the Siegburg Bay, and in the south into the Honnef valley widening as part of the Lower Middle Rhine area , bordered in the east he to the Siebengebirge as well as the Pleiser Hügelland (mountain range Ennert ) and in the west to the Oberwinterer Terrassen- and Hügelland and the Kottenforstterrasse (all lower Middle Rhine area).

description

The natural area extends as a valley widening especially on the left bank of the Rhine over a length of about eight kilometers in north-south direction along the river bed , which is about 400 m wide at this point , with a width of up to four kilometers. It forms a funnel-shaped transition from the Lower Rhine (Cologne) Bay to the Rhenish Slate Mountains, tapering up the Rhine , thus marking the transition from the Middle Rhine to the Lower Rhine .

By far the largest part of the natural area is taken up by the loess- free lower terrace with its up to two meters thick layer of clay . At Plittersdorf it drops off with a clear bend of around five meters to the so-called island terrace . At the Mehlemer Bach and the Godesberger Bach , small strips of the central terrace have been preserved.

The outer contours of the Rhine valley funnel are formed on the left bank of the Rhine by the steep slope of the younger main terrace , which is over 100 meters higher , and on the right bank of the Rhine by the volcanic peaks of the Siebengebirge, which come close to the bank. The basalt cone of the Godesburg ( 120.8 m above sea  level ) is a striking elevation and natural spatial singularity within the Rhine valley funnel  .

Localities

Within the Godesberg Rhine Valley funnel, on the left bank of the Rhine, are the following districts of the city of Bonn (from south to north): Mehlem , Lannesdorf , Muffendorf (partially), Pennenfeld , Rüngsdorf , Alt-Godesberg , Plittersdorf , Friesdorf , Hochkreuz (district of Bad Godesberg), Dottendorf and Kessenich ( City district Bonn). The narrow strip of the natural area on the right bank of the Rhine extends over the city of Königswinter (city center) and the districts of Niederdollendorf and Oberdollendorf as well as part of the Bonn district of Oberkassel (district of Beuel ).
