Kurzfassung/Abstract

Full-depth snow avalanches as a geomorphic process are investigated in this study, which is part of the SEDAG (SEDiment cascades in Alpine Geosystems) research project. First results concerning the sediment yield of these events were presented in an earlier paper (HECKMANN ET AL. 2002). Here, they are supplemented with new data and a description of certain models constituting our modelling approach. A disposition model (certainty factor model) is used to determine potential avalanche starting zones, while a process model delineates the potential process area (lateral spread and runout length) along with modelling flow parameters (e.g. velocity).
First steps towards spatial modelling of the geomorphic activity of snow avalanches, i.e. erosion and deposition of soil and debris, are presented on the basis of empirical correlation with flow parameters.
