Abstract

The aim of this study is to compare different methods and to conclude on suitability for the determination of alpine soil erosion. Furthermore, the advantages and disadvantages of the single measurement methods with regard to alpine basins are focused. The AA. distinguish between sediment traps and sediment cups to determine erosion rates bi-weekly in 2007 and 2008, and Cesium-137 based measurements to measure long term erosion rates since 1986. They investigate 3 different land cover types : hayfields, pasture with dwarf shrubs and pasture without dwarf shrubs in the Urseren Valley (Central Switzerland) with a mean slope steepness of 37°. The combination of all three methods turns out to be useful for erosion quantification and process understanding
