Monsoonal variability and erosional processes on decadal to millennial timescales control the impact of climate variability on glacial, fluvial, landslide- and debris-flow erosion on different time scales in the NW Himalaya, a transitional area between the summer monsoon and westerly precipitation regimes. The present day moisture transport will be determined from remotely sensed rainfall, snow-cover and glacial velocity data as well as gauging station runoff, There will be a combination between the analysis of remotely sensed data on moisture transport with water and lipid biomarker stable isotope analysis to constrain organic matter sources and to decipher transport and erosive processes within a large fluvial catchment in the Indian Himalaya. By using sedimentological archives (river terrace sediments, lake sediments) wet will try reconstruct changes in these processes over time and relate them to monsoonal variability during the Holocene.
