A proper understanding and prediction of movement and transfer of sediment and associated nutrients and contaminants through river basins is indispensable for an adequate management of sediment quantity and quality. Despite the substantial progress that has recently been made in the measurement and modelling of erosion and deposition of sediments on hillslopes, in the river channel network, and on floodplains, it remains difficult to predict the fate of sediments at the river basin scale. This session aims to bring together hydrologists, geomorphologists, and soil scientists working on fine to coarse sediment transfers at spatial scales from small catchments to large river basins and at time scales from storm events to centuries. This session solicits contributions that examine the amounts and rates of transfers and storage of sediments and associated nutrients and contaminants in the various compartments of the fluvial system from hillslopes to estuaries. Abstracts that address transfers of sediment between river basin compartments, sediment retention time within the compartments, or transit times of sediment in river basins are especially welcome.
