Abstract : This is a simulation program designed to analyze scour and deposition by modeling the interaction between the water-sediment mixture, sediment material forming the stream's boundary and the hydraulics of flow. It is sometimes possible to separate sedimentation studies from those involving the hydraulics of flow. For example, deposition in deep reservoirs can be studied from the standpoint of a reduction in reservoir storage capacity because there is no reentrainment of material once it is deposited. On the other hand, sedimentation studies in shallow reservoirs, downstream from dams or in natural rivers require treatment of the entire movable boundary problem because both scour and deposition are involved. It is for this more general case of problems that this simulation model is designed. This is not a sediment yield program per se. It simulates the ability of the stream to transport sediment and considers the full range of conditions embodied in Einstein's Bed Load Function plus silt and clay transport and deposition, armoring and the destruction of the armor layer.
