Research Abstract

In this study,' Numerical Wave Flume' for a resilient design of coastal structures against violent waves was constructed by introducing free-surface flow models, including particle method. The characteristic of numerical models were investigated by 4 types of benchmark tests. And GPGPU computing was introduced tomake calculation as fast as possible. One of the tsunami disasters in the Tohoku-Pacific Ocean Earthquake was simulated by' Numerical Wave Flume' to examine its applicability
