Abstract
The primary mitigation measure for flood disaster is to develop effective evacuation strategies and to implement disaster education. A Comprehensive Scenario Simulator in Flood Time was developed as a tool to optimize the warning system and evacuation. The simulator combines hydrodynamic simulation of flood with warning and human-response simulations for evacuation. Therefore, the use of this simulator can be twofold: One as a strategy tool to examine effective flood disaster mitigation measures. Two, because of its visual presentation, this simulator can be used as a risk communication tool to learn about various disaster phenomena and appropriate actions to be taken to reduce the impact of flood disasters.
