摘要
Purpose Quantifying suspended sediment fluxes and dynamics across mountains, and identifying the origin of sediment in severely eroded areas, are of primary importance for the management of water resources. This contribution aims to generalise previous results from suspended sediment fingerprinting obtained during 2007–2009 in a mesoscale Alpine catchment (the Bléone River; 905 km2) in France, and to assess variability in sediment sources throughout the second half of the twentieth century.
