Abstract

The numerical model for three-dimensional beach change prediction is constructed to simulate a pocket beach formation. The model consists of three modules of waves, currents (include beach change) and sediment transport. Wave transformation module is based on the mild slope equation of hyperbolic type, current module is horizontally two-dimensional with direct interaction with sea bottom change which is evaluated by sediment transport model formulated by Bailard. Numerical simulation of pocket beach formation was performed under two conditions of an artificial pocket beach formation which is the typical case of beach stabilization by headlands and an empirical pocket beach which is made by combining an equilibrium bay and beach profile.
