| Outline of Final Research Achievements |
When a large-scaled tsunami attacks on a caisson breakwater, a tsunami overtopping flow falling on a mound or a sand bed can induce a scouring, a bearing capacity can be gradually lost, and then a caisson can overturn. In order to simulate this kind of failure process of a caisson breakwater, a numerical model is needed to have an ability for solving the interaction among a wave deformation, a caisson behavior and deformation of mound and sand bed. In this study, a numerical model satisfying this requirement is developed, and its applicability is examined.
