A superposed inundation simulation is conducted on the conditions, the sewer does not function and the probable rainfall is 1000 years, for a compound water disaster in which inland and foreland waters inundation occured at the same time, targeting the second-class river Gobo River in Takamatsu City, Kagawa, JAPAN. The results show that the inundation area increases and the flow velocity partly increases in the compound water disaster compared to the cases where the inland and the foreland inundations are occurred individually. Therefore, it is assumed that the difficulty of evacuation will increase, and it will be necessary in the future to consider superimposed inundation on the hazard map of water disaster.
