Abstract

Cities often have numerous underground spaces such as subways and shopping malls. These hold the possibility of being inundated in a disaster. The reasons of these disasters are urbanization and global warming. The vulnerability of underground spaces to extreme flood and evacuation from there are treated in this paper by using the results obtained by numerical methods in densely urbanized area, Osaka, Japan. It is found that up to 60% of water would flood underground spaces if no counter measures were taken. It was also confirmed such areas should be evacuated before inundation.
