A Basic Study on Ship Drifting by Tsunami

Abstract

Tsunami attack generates not only the raise of sea surface but strong horizontal current in the bay It is very important for marine disaster prevention to grasp the drifting motion of the vessel caused by the tsunami curent. According to the ship drifting simulation by tsunami at the bay of Owase, Mie Prefecture, we found a possibility that a vessel collides with a berth, and also a possibility of ship grounding by the tsunami current. Such results suggest that still more detailed examination is required in the future
