Energy Relations for Suspended Sediment Transport

Document Type: Proceeding Paper

Part of: Sediment Transport Modeling


One of the main difficulties in predicting transport rates of suspended sediment on the basis of the Rouse-expression for relative sediment concentrations, is the lack of any reliable information about the reference concentration, Ca. As the sediment suspension process consumes energy, it appears appropriate to infer Ca from the energy balance of a sediment-laden flow. Energy relations also explain how the structure of the flow is modified in the presence of sediment suspensions.
