Modelling Beach Topography Evolution Due to Waves and Currents in the Vicinity of Coastal Structures

Summary, in English

A numerical model of beach topography evolution due to waves and currents in the vicinity of coastal structures was developed. The model consists of five sub-models for nearshore random wave transformation, surface roller development, wave-induced currents, sediment transport, and morphological evolution. It was validated based on high-quality data sets from the Large-scale Sediment Transport Facility at the Coastal and Hydraulics Laboratory, in Vicksburg, Mississippi, USA. The simulations discussed here showed that the model well reproduced hydrodynamic conditions as well as beach morphological evolution in the vicinity of a detached breakwater. Previous simulations have confirmed the applicability of the model to simulate the conditions at other breakwater configurations and T-head groins.
