M-SHORECIRC:AMorphodynamic Model

, able to simulate the short-term evolution of nearshore sandy regions, is presented. The model is based upon the hydrodynamic model , coupled with a sediment transport module for the estimation of the sediment transport rates, and a sediment conservation equation solver. Presently, it uses the sediment transport equation of Soulsby-Van Rijn, which calculates the total transport for non- cohesive sediments, in combined waves and currents, over horizontal and sloping beds. The present simulations focus on the growth of rhythmic surf zone bottom features, consisting of shoreline-attached normal and oblique bars, and quasi-uniform alongshore bars. M-SHORECIRC ABSTRACT
