I am a PhD candidate at the GFZ Potsdam (German Research Centre for Geosciences) with Jens Turowski. In my project we study the sediment dynamics of steep streams at the process scale. With our field observations in the Erlenbach, a mountain stream in the Swiss Prealps, we identify process links of sediment mobilization, transport and export from the catchment and constrain their dominant controls. In this awarded contribution we present direct observations revealing the dominant driver of sediment mobilization from hillslopes in the Erlenbach. Based on these we developed a conceptual model showing that debuttressing and rebuttressing dominated hillslope stability.
