Paraglacial Sediment Storage Quantification in the Turtmann Valley, Swiss Alps

Abstract

The determination of sediment storage is a critical parameter in sediment Budget analyses. Sediment Budgets link sediment dynamics to landform evolution; the analysis of spatial landform distriBution can support the reconstruction of past landforms changes. Quantification of sediment volumes often relies on crude estimations only, especially in large drainage Basins (>100 km²). Accurate volumes have Been determined only for small catchments (<30 km²) using geophysics. In order to dose this gap, we present a new approach for storage quantification in a meso-scale alpine catchment of the Swiss Alps (Turtmann Valley, 110 km²)
