Abstract

We performed model experiments on the inundation flow of tsunamis with ice floes. After the collision force imparted by the ice floes acts on structures, the tsunami flow is dammed by the formation of ice jams between the structures, and a large static force also acts on the structures because of the water level rise in front of the structures and because of hydrostatic pressure between the structures due to the ice-jam, and this steady state remains for some time. We developed a simple theoretical model for estimating the water depth and the tsunami force, and we verified the validity of the model.
