NUMERICAL SIMULATION OF STORM SURGE INUNDATION INDUCED BY OVERFLOW, OVERTOPPING AND DIKE BREACH

摘要

A new scheme of numerical simulation of storm surge has been developed recently.With this simulation model, abnormal high storm surges generated by large typhoons around the coasts of Japan were well reproduced. Furthermore, numerical simulation model for storm surge inundation is developed to study and prevent storm surge disasters on Japanese coasts. Inundation simulation method induced by overflow, overtopping and dike breach is incorporated into this model. With this inundation simulation, coastal protection works consisted of hard and soft countermeasures can be designed. This paper presents the application to Ise Bay.
