A STUDY ON POSSIBLE CRITICAL STORM SURGE UNDER PRESENT CLIMATE CONDITIONS IN THE ARIAKE SEA, JAPAN

[摘要] In this study, to understand the characteristics of storm surges along the coast of innermost area in the Ariake Sea, the tidal changes at three points along the embankments were measured for about three months in the summer of 2012. In addition, several storm surge simulations were conducted by using the parameters of an actual Typhoon No.16 (T1216) to investigate the possible large storm surge in the Ariake Sea under the present climate conditions. The observational results show that the storm surge amplifies remarkably in the innermost area in particular. Furthermore the numerical simulation results imply that there is the risk of serious storm surge disaster in the Ariake Sea under even the present climate condition.
