| Outline of Final Research Achievements |
This study is intended to establish the real time estimation method of tsunami inundation and to investigate generation mechanism of tsunami induced hazard like a local scour which causes severe damage on coastal dike or breakwaters. Moreover, tsunami force on structures is investigated and its estimation method is studied. Though the present study, the real time simulation method has been successfully established and its reliability has improved by considering stochastic approach. As far as tsunami induced hazard is concerned, numerical simulation method to evaluate local scour behind coastal dikes has been developed considering in/exfiltration flow and suspeded sediment transport which play important role on actual event. The model was also improved to consider the effect of viscosity change due to suspended sediment. This effect was also examined in the estimation method of tsunami force on the structures. The tsunami force on the structure was also investigated in the study.
