Parallel session: Poster pitch: 2I: FloodRisk - Adaption
The multi-environment zones (i.e., with various geographical risk factors) have very high potential disaster risks. In addition, the current natural disasters have occurred complex set of factors according to the debris flow and urban inundation in multiple-environment zones between urban areas with high and low mountainous areas. In order to mitigate these disasters more effectively by a countermeasure, it is necessary to investigate what causes the damage from the overall natural disasters simultaneously. However, it is very difficult to predict the disasters in the foreseeable future as well as to analysis the accident cause of disasters. Therefore, emergency evacuation system should be established by considering of feed-back from each disaster. The objectives of this study are to estimate the risk evaluation index according to 2-D debris flow with 2-D urban inundation models, to determine the PMP (probable maximum precipitation) and run-off discharge due to the DAD analysis for estimate the external force condition. Finally, the multi-hazard risk maps, evacuation plans and evacuation route maps combining both disasters according to the EES (emergency evacuation scenario) are proposed by a GIS (Geographic Information System).
