| Research Abstract |
A tsunami attack on the coast would not only increase the sea level, but would also create strong horizontal flows in bays and ports. It is very important from the viewpoint of marine-disaster prevention to gain a better understanding of the motion of ships originating in tsunami flows and to develop countermeasures in the face of a tsunami attack. A new evaluation system of ships movement under the tsunami attack has been established by use of computer fluid dynamics method. As the results, it enables the simultaneous estimation of the movements and mooring forces exerted on moored ships in the case of a tsunami wave.
