Abstract

A numerical wave model based on the Boussinesq equation was extended to the computation of two-dimensional wave-current field including diffraction, refraction and wave breaking. The energy dissipation due to wave breaking was modeled by a momentum mixing term using eddy viscosity. Beach deformation was estimated based on the wave-current field simulated in the nearshore region. Energetics-based equations were used to estimate the total sediment transport in the cross-shore and longshore directions. The model applicability was confirmed with laboratory experiments.
