Sediments on the earth's surface are continuously rearranged, with rivers playing a particularly important role. Rivers continuously transport sediments from the place of production (e.g. mountain slopes) to another deposition site (e.g. to the oceans). The properties of the sediments produced (chemical composition, quantity, particle size distribution) vary according to local conditions. Sediment deposits are therefore used to reconstruct environmental conditions from the past. These sediment properties, on which the reconstructions are based, are modified in the course of transport along the rivers, which makes the reconstructions more difficult.
On the one hand, we investigate the relationships between local environmental conditions and the properties of the sediments produced. Furthermore, we investigate sediment transport along river systems, changes in sediment properties during transport, and the influence of sediments on the morphology of the channel bed itself. Based on this we reconstruct environmental conditions from the past by a detailed analysis of sedimentary properties in sedimentary sediments.
The interaction of soil hydrological parameters and precipitation properties determines how the stand precipitation is distributed on and in the topsoil. In particular, we investigate under which circumstances these parameters and their spatial patterns affect the formation of surface runoff.
We develop the MATLAB-based software for the analysis of digital terrain models. TopoToolbox finds applications in tectonic geomorphology, but also in hydrology, glaciology and natural hazard research.
