Abstract

This study quantifies sediment deposits of different high alpine landforms in a meso-scale alpine catchment of the Swiss Alps (Turtmann Valley) by applying a combination of geophysical surveying and GIS modelling techniques at different scales. Mean thickness values of each landform type calculated from these data was used to estimate the sediment volume in the hanging valleys and the trough slopes. Sediment volume of the remaining subsystems was determined by modelling an assumed parabolic bedrock surface using digital elevation model (DEM) data. As the quantification approach includes a number of assumptions and various sources of error the values given represent the order of magnitude of sediment storage that has to be expected in a catchment of this size
