| Outline of Final Research Achievements |
For effective design of breakwaters against huge tsunamis, complicated damage process, e.g. sliding of a caisson, scouring of the mound, drifting of blocks should be considered comprehensively. The numerical wave flume is expected to approach this challenging issue, however, this kind of phenomenon comprises prudent scaling effects under the violent flows, and as a result, it is difficult to treat them with a practical computational cost. In this study, improved boundary models are introduced into the so-called accurate particle method in order to resolve this problem. The proposed model includes DEM-MPS coupling model and a multi-resolution scheme so as to develop the comprehensive, accurate and stable framework for violent solid-liquid multiphase flows.
