Numerical Simulation on Scour behind Seawalls Due to Tsunami Overflow
During the Great East Japan Earthquake of March 11, 2011, many protective structures were damaged by tsunami overflow. Some previous results of researches indicate the declining of the safety factor of bearing capacity due to scouring near the foundation of structures. However, the relation between scouring depth and overflow parameters has not yet been well understood. In this study, the scouring depth due to tsunami overflow is investigated by using numerical model based on SPH method and the numerical results are compared with those of the physical model tests. The analysis of numerical results concludes that the maximum depth of scouring is proportional to the height of overflow and is inversely proportional to the falling height of the overflow over the dike.
