We measure soil erosion in hydrological catchment areas and develop and improve models for erosion prognosis. Furthermore, we examine the connections between erosion by surface runoff and their influence on our waters. Based on these findings we develop and test measures for surface water protection.
Soil erosion impairs the functional capability of soil and waters. It is considered the biggest threat for damage on our soils worldwide.
Experiments with simulated rainfall allow us to observe soil erosion and surface run off on small areas. These experiments enable us to strongly control the environmental background conditions.
Plot experiments make it possible to observe soil erosion and surface runoff to a size of single fields. Controlling environmental background conditions is only partly possible.
The observation of runoff, as well as the transport of particulate materials and nutrients in hydrological catchments is a crucial instrument for spatial management of the water and matter cycle.
