Abstract
The coastal structure may collapse due to beach erosion and scour. There are few cases that tried to analize the scour of coastal sturucture affected by tsunami. In numerical simulation, a particle method is suitable for tracking complicated surface water motion and sand movement. In this study, we performed the reproducible analysis of the toe scour of a seawall of the large-scale experiment using numerical simulation based on an accurate ISPH method. As a result, it is proved that the waveform and velocity of the first wave are accurate by reproduced. The behavior of scour can also be reproduced by the ISPH method.
