Knowledge on the flood risk due to tsunami and storm surge is slight in the persons living in coastal urban areas. The information of the size of anticipated damage and influence to evacuation routes is not enough for them to minimize the hazard risk by inundation.
In this research, the inundation in the coastal urban area caused by tsunami attack is analytically estimated, and the display system on the website was developed. The site is capable for sending the understandable information on the risk through the internet.
The inundation calculation was conducted according to the characteristics of the land use of coastal area, and the relational expression was derived between the distance from the seawalls line and the arrival time, the maximum depth, the maximum celerity. It is possible to display the inundation risk of the maximum design tsunami on the target coastal regions.
