Research Abstract |
Vertical profile of eddy viscosity is modeled in wave breaking and swash zones. It enabled to get vertical profile of suspended sediment. Quasi-3D sediment transport model coupled with the higher order Boussinesq model was developed. Bypass sediment flux around headlands was observed at the Yamamoto coast, the prediction model of which was developed. It is shown the bypass flux is effectively controlled by adjusting the length of the head.
