The morphology of the river valleys depends on the amount of the water
delivered. By morphology we do not only understand the width of the
valley: the term also includes the development of the bends. The more
abundant the water discharge of a river is, the larger bends it forms.
If we consider that the water discharge of a river varies widely even
within a year, the more so it was in the various geological ages. The
bend development of long abandoned riverbeds indicate the water
discharge conditions of old ages. Therefore, a geographer always
becomes suspicious if he sees a small brooklet – that cannot be even
properly called a stream – running in a large and wide valley. The
Wellheim valley in Bavaria is such a place.
