Abstract
Increase of damage caused by storm surge is one of the important effects of global warming. It is necessary to know quantitatively the relationship between sea level rise/ tropical cyclones trengthening and damage of storm surge. The researcho bjectivei s to formulate a climate-change susceptible function on storm surge damage. For that purpose, the author built the numerical model that explains inundation state under storm surge. The information of topography and coastal facilities is given as spatial mesh data in the model. The fluid motion is described by linear long wavest heory. Seawater is considered to flows intol and as seawallo verflow. Run up is calculated by Iwasaki and Mano's method. In the first step of making the nationwide model, the author built the model of inner parts of three major bays in Japan, which have large populations and properties. A ccording to the calculation, the inundation areas had tendencies to increase in small rate in the early stage corresponding to increase of atmospheric pressure of typhoon eye, but had tendencies to increase rapidly from certain typhoon pressures and sea levels.
