| Research Abstract |
In urban conglomerate cities extensively developed in bay area, flood-related hazard zoning, evaluation of losses due to storm surge and river flood, and evaluation of the effficacy of various structural and nonstructural measures are essential in planning strategy for hazares. This study mainly aims to present the method to predict the hazardous area due to storm surges and river floodings. Presented method, by which the occurrence of storm surges and the results of the flooding of protected low-lying areas are estimated, has been shown to be very useful for the assessment of countermeasures taken against storm surges. Zones at risk of storm surge flooding after the 21st century rise in sea level caused by the greenhouse effects could be predicted by this simulation model. A rise in sea level of 65cm would cause severe inundation in Osaka Bay Area about two and half times that flooded in a designed typhoon before the rise in sea level. If the predicted rise in sea level is valid, new countermeasures will have to be taken against storm surges in Osaka Bay area. Our simulation model and the results calculated from it can be used as the basis for the design of such countermeasures.
