Thickness and structure of alpine slope sediments derived from geophysical investigations

Understanding regional sediment budgets requires the quantification of stored material in sediment sinks. However, our knowledge of talus slope and basin volumes is still fragmentary. Geophysical investigations frequently offer the only opportunity of achieving significant results on debris volume and composition. The aims of the studies were (1) to gain insight into the inner structure of alpine sediment bodies using ground-penetrating radar (GPR) and further geophysical techniques, (2) to provide an estimate of long-term weathering and removal rates by measuring the total volume of debris accumulated on slopes and in basins and (3) to compare these values to short-term measurements of current processes and find reasons for discrepancies.
