2019年台風15号の高潮・高波による 横浜市金沢区福浦・幸浦地区の浸水分布と企業被害の実態

抄録

Typhoon No. 15 in September 2019 caused significant storm surge damages to the Fukuura and Sachiura areas in Yokohama City, Kanagawa Prefecture. Based on the results of a questionnaire survey and a field survey, this study clarified a distribution of inundation depths on land and evaluated relationship between the inundation depths and damages to industries. As a result, we found that the storm surge inundation occurred widely in the coastal areas more than assumed in a hazard map, and that manufacturing industries that handle materials vulnerable to water, such as paper and pulp, were more likely to suspend operations even at relatively shallow inundation depths. Additionally, the number of days businesses were suspend due to storm surge tended to be longer than other water-related disasters.
