Kurzfassung/Abstract

This study aims at quantifying and modelling the contribution of snow avalanches to the sediment balance of alpine catchment areas. It is part of the SEDAG research project (SEDiment cascades in Alpine Geosystems) taking place in two drainage basins in the northern limestone Alps (Lahnenwiesgraben / Ammergebirge mountains, Reintal / Wetterstein mountains) near Garmisch-Partenkirchen / Southern Germany. In spring of 2000 and 2001, numerous avalanche deposits were mapped and sampled to calculate their sediment yield. First results (64-327 t/a per catchment area; ca. 1 kg-170 t per single avalanche event) lead to the conclusion that avalanches contribute significantly to the sediment balance and relief development of high mountain areas. Their impact is, however, highly variable in time and space. It is the aim of our ongoing work to predict potential sediment yield and to locate erosion, transport and deposition of sediment by avalanches.
