Abstract: In 2011, the example that breakwaters collapsed because of the basic ground’s destabilization was reported by Tohoku-Kanto earthquake tsunami. Fluid-Structure-Soil coupling simulation is desired for a systematic comprehension of the breakwater collapse mechanism, and it may help to develop next disaster prevention method. In this study, as a first step, this simulation should treat the surface flow and seepage flow interactions. A particle simulation tool based on the SPH has been modified and improved to solve this interaction problem.

Keywords: ISPH method, Seepage flow, Porous flow, extended Darcy’s law,
