In the last decade, torrential rain has been increasing and it caused pluvial and fluvial flooding in Japan. These floods caused inundations in urban and rural areas. Intensity of such rainfall was sometimes excesses over the design rainfall of drainage systems and rainwater was running over the road. In these floods, some portion of rainwater intruded into underground spaces and the users faced the danger of underground flooding. In this paper, pluvial flooding was investigated by InfoWorks CS and underground flooding in a mega-underground mall was also discussed on the bases of calculation by shallow flow model with structural mesh. And then, the effects of counter measures for reducing underground inundation were studied with the criteria of safe evacuation obtained by the previous evacuation tests.
