For realization of tenacious structure, it is significant to investigate the influence of scouring behind the seawall due to tsunami overflow. Although studies have been made on the estimation of maximum scour depth, there is few studies on the relationship between overflow time and scour depth. In this study, we conducted the scour experiments and analyzed the experiment in order to design the estimation equation of scour depth. And, we investigated the scour depth of the seawalls at Hachinohe Port which were damaged by tsunami overflow.
