Abstract
<p> In recent years, sea level rise and intensification of typhoon which are induced by global warming have been feared. It is, therefore, important to estimate the flood characteristics caused by potential maximum typhoon, and evaluate the mitigation effect of tide gate on storm surge. In this study, we simulated storm surge around Nagoya port caused by two potential maximum typhoons, which are the present and SRES A1B scenarios, using improved “T-STOC” for storm surge analysis. The numerical results revealed that maximum storm surge level is about 2m higher than Isewan Typhoon in 1959 and a wider range of below-sea-level area is flooded. It was also found that closed tide gates can delay the start time of inundation, but the evacuation time is very hard to keep once the storm surge flows over the gate.</p>
