Simulation of General Sediment Transport in Rivers and Reservoirs

CCHE1D and CCHE2D sediment transport models (including FVM-based and EEM-based versions) have been widely applied to the simulation of general sediment transport in rivers and reservoirs. The 1D and 2D models are designed for nonuniform sediment transport modeling, and can handle sediment selection, bed material hiding, exposing and armoring. These models can predict very well channel aggradation and degradation patterns, as well as the sediment transport characteristics.
