Abstract
 It is predicted that the storm surge damage due to climate change may be more serious in the world. The objective of this study is to verify the estimation method for economic damage of storm surge, focusing on the case of Isewan typhoon. This study compares the two estimation methods of storm surge damage using the case of Isewan Typhoon. Specifically, the economic damage was estimated by two methods: 1) the method based on flood control and the economic research manual and 2) the method based on macro socio-economic indicators such as GDP and affected population. It was found that the former estimated the damage 10 times as large as observed one and the latter estimated the damage smaller than the observed one.
