A NUMERICAL MODEL FOR BEACH DEFORMATION AROUND RIVER MOUTH DUE TO WAVES AND CURRENTS

Tomoya Shibayama, Akiko Yamada

Abstract


A numerical model Is proposed for beach deformation under wave and current in river mouth area. The model includes three major driving forces for sediment transport which are wave, wave-induced current and river discharge. Interaction of wave and current is also included. Laboratory experiments are performed to be compared with numerical results. Wave field, current field and beach deformation are compared between laboratory and numerical results and good agreements are obtained.

Keywords
