高潮浸水シミュレーションによる三大湾奥部の浸水被害の感度解析

抄録

Three major bays in Japan have large low-lying lands. Inundation damage there by storm surges is increased by sea level rise and typhoon strengthening due to global warming. For estimating this damage, numerical models that describe storm surges, waves and inundation were built up. Then, damage graphs that output damage index from sea level rise and typhoon strengthening were drawn based on calculations by the models. The graphs showed that inundation area, inundated population and amount of loss increase rapidly at typhoon strengthening ratio 1.0to 1.3.
