Grain size distributions of Bossons stream sediment bedload (France) in 2011

This dataset presents sediment load grain size distributions of Bossons stream, one of the subglacial stream draining Bossons glacier meltwater. Bossons glacier is rapidly retreating and its proglacial area is deglaciated for ~30 years. Within this area, Bossons stream flows through an alluvial plain with day-to-day morphological changes. It is an intriguing location to study periglacial and proglacial erosion processes which requires to characterize transported sediments. Since coarse particles are difficult to monitor in such alpine stream environment, this dataset focuses on fine grained particles in suspension load, saltation load 5 cm from bed and bedload. […]
