In this paper, a numerical model DIVAST (Depth Integrated Velocities And Solute Transport), which can predict two-dimensional depth-integrated tidal flows and solute transport, has been refined and set up to stimulate hydrodynamic and sediment transport processes. The highly accurate ULTIMATE QUICKEST scheme has been used to represent the advective terms in solving the advective-diffusion equation for suspended sediment transport. The model has been applied to simulate tidal flows and sediment fluxes in the Bristol Channel and Severn Estuary in the U.K. The predicted velocities and water elevations have been compared with three sets of Admiralty Chart data. Comparisons between the numerical model predictions of sediment fluxes and field data were made at two sites along the estuary where field data existed. The resulting comparisons are encouraging.
