The numerical model CSHORE predicts beach evolution over the nearshore region, and a full description of the model development is available in Kobayashi et al. 2009. The combined wave and current model operates under the assumption of longshore uniformity and includes the effects of a wave roller and quadratic bottom shear stress. The numerical integration of the depth-averaged energy, momentum, and continuity equations results in predictions of wave height, water level, and wave-induced steady current. The development of new and physically defensible sediment transport algorithms for a nearshore breaking wave environment has been the focus of the most recent research efforts. The model accounts for wave and current interaction, bedload, suspended load, and wave-related sediment transport. The interested reader is referred to Kobayashi et al. 2009 for a detailed description of the model formulation of these processes.
