Suspended load often represents the most significant fraction of sediment load in rivers. The transfer of these fine particles produced on hillslopes and transported through the river system is poorly understood in Alpine rivers. However, fine particles transport is associated with social, economic, and ecological issues such as pollutant transfer, riverbed clogging, vegetation growth, or reservoir siltation. In this context, the objective of this study is to characterize the interactions between suspended load and the riverbed of La Severaisse (Ecrins Massif), a typical Alpine river. To this aim, we applied a short-term sediment budget approach based on high frequency suspended load measurements on a 3.5-km reach. In addition, we measured bedload transport through direct sampling. The results indicate that suspended load is significantly buffered in the studied reach during the two-month campaign. Moreover, conditions leading to the mobility of coarse particles were found to evolve concomitantly with conditions leading to fine particle mobilization. These observations bring new insights in understanding the transfer of suspended material in Alpine rivers.
