Abstract

An existing numerical model system of bathymetric change due to wave action and wave-induced currents has been extended to simulate combined flow fields by wave-induced and unsteady tidal currents as well as the consequent bathymetric change. The combined flow field is obtained by a direct interactive calculation instead of linear summation of both flows. In order to save computation time the tidal variation during a cycle is divided into several flow phases, and each phase is treated as a quasi-steady flow in the model system. The model system has been app
