Unterhalb Altmühlmündung
The central section of the river Danube in Germany
The sub-area Unterhalb Altmühlmündung (downstream of the mouth of river Altmühl) lies in the middle reaches of the Danube in the Munich Gravel Plain north of the Hallertau.
The size of the Danube increases significantly by the confluence with the Altmühl and changes its character from the upper reaches to the middle reaches. The Altmühl connects the Danube with the Rhine-Main-Danube Canal and hence with the Rhine.
This section of the Danube is used as shipping route and the sub-area is therefore characterized by extensive straightening and chains of barrages. Furthermore, the river banks of the main stream are almost completely reinforced by gravel.
