| Research Abstract |
Web camera monitoring system has been installed in Shichiri-mihama Ida beach. New detecting method of a shoreline from camera image has been proposed and characteristic of shoreline change was discussed in relation with incident wave properties. Fully nonlinear direct numerical simulation method has been developed in this study and applied to simulate flow field where wave and current co-exist. Results show that the density profile affects on the flow field and that artificial reef has an influence of mean surface level and flow field. Also sediment transport on the trapezoidal mound has been investigated and it was found that profile change due to wave can be estimated by the numerical method proposed in this study.
