At the intermediate scale the river basins of the Rhin, Nuthe and the lower Havel are studied.

The Rhin with a basin area of 1.780 km2 is the third largest supply to the Havel, following the Spree and the Nuthe. He originates in a lake area in the south of Mecklenburg Vorpommern and is characterized by a comparatively high flow gradient. Wide lakes and the famous Rhinluch characterize itís river bed till the Havel main stream. Itís total lenght is 125 km.

The Nuthe originates in the Flšming region and flows north to the Havel main stream. Itís total basin area is 1.872 km2. The slope from the spring at 80,3 m.a.s.l to the Havel near Potsdam-Babelsberg (28,5 m.a.s.l.) amounts to about 52 m. Lage parts of the Nuthe basin represent former drainage areas, which were meliorated more than 100 years ago and are used agriculturally till today. Since the northern part of the basin was used for sewage purposes from the beginning of the 20th century til the mids of the 80th, considerable water quality problems are still evident.

bullet

The Lower Havel (about 2.000 km≤) is mainly characterized by greenlands and represents an area with a strong exchange of ground- and surface water. Therefore, it strongly influences the discharge dynamics of the main river course. Main modelling goals in this region are a description of the discharge dynamics between Rathenow und Havelberg, which have a considerable impact on nutrient exchange and transport processes.
