Research Questions

Floodplains are important landscape elements connecting streams with their catchment. While strong gradients of biogeochemical parameters are often observed in organic-rich floodplain sediments, the strength of groundwater flow through reducing sediments determines how important these zones are for the receiving water body.

The floodplain of River Ammer between Pfäffingen and Tübingen is fairly typical for the hilly landscapes found in Triassic geology. Like in many other cases, the hydrology of this floodplain is poorly understood regarding three main aspects:

These hydrological factors influence the fate of nitrate and other pollutants introduced at the hillslopes and in the floodplain of the Ammer valley. They are determined by the internal structure of the floodplain sediments and their hydraulic properties.

 

Approach

In project P3, we combine hydrogeological and geophysical techniques to determine

We will install observation transects along the direction of groundwater flow for itensive monitoring campaigns in cooperation with project P4, and perform tracer tests moitoried by classical techniques and geophysical imaging to elucidate the flow field and groundwater travel times.
