Description :
Bedload, the transport of sediment remaining in contact with the stream bed, has mainly been studied from the perspective of the correlation between fluid driving forces and the responding sediment flux. Yet grain–grain interactions are important and bedload should also be considered as a granular phenomenon. The AA. review progress made recently in the study of granular flows, especially on segregation and rheology, that better illuminates the nature of bedload. Mutual study of these phenomena may benefit both physics and fluvial geomorphology.
