A FUNDAMENTAL STUDY ON THE EFFECTS FOR REDUCTION OF LOSS OF LIVES FROM BREAKWATERS AND SEAWALLS

Abstract

 In this study, the analysis of tsunami evacuation based on cellular automata method is proposed. Because the problems of tsunami evacuation simulation in order to plan for effective breakwaters and seawalls to the reduction of loss of human lives by the tsunami was considered. Tsunami evacuation using the shortest route to the end point and inundation that changes from moment to moment are uniformly analyzed based on cellular automata method. Accordingly, the point where the damage to each evacuation start time occurs are shown if the fastest escape route is used. In this paper, it is considering changing the specifications of the breakwaters and seawalls of Shimizu. Then, the possibility of loss of human lives is increased is revealed by the multiple placement of tsunami measures. Also in this paper, the existing development plan on tsunami measures in Shimizu Port is referred. From the study results, measures should be given priority in development is estimated that raising the breakwater.
