We plan to quantitatively explore the human impact on erosion and fine sediment transfer in the Rhône drainage basin, which is the largest inner Alpine system. In this basin, anthropogenic flow abstraction and river regulation during the past decades have had a measurable impact on the transfer of sediment as documented by a decrease in sedimentation rates in Lake Geneva, the primary sedimentary sink of the Rhône River. Our aim is to analyse quantitatively the sediment fate in the changing Rhône basin during the late Anthropocene, and to test basic hypotheses, which explain the changes in sediment production, transfer and deposition rates. We will focus on considering three critical question areas: (i) What are the precise timings, amplitudes and patterns of change? (ii) Where are the sources responsible for the change? (iii) What are the mechanisms responsible for change, and what is the role of human activities in this context? To address these questions, the project brings together sedimentologists (UNIGe), geologists (UNIBe), geomorphologists (UNIL) and hydrologists (ETHZ) to disentangle natural climate variability, climate change and long-term geologic forcing from human impacts in a collaborative effort.
