DEVELOPMENT OF HUMAN DAMAGE MACRO EVALUATION METHOD FOR CATASTROPHIC FLOOD DISASTERS CONSIDERING DISTRIBUTION OF MID-TO-HIGH-RISE BUILDINGS IN NEIGHBORHOOD

Abstract

The authors proposed an evaluation method for lifesaving countermeasures against extreme condition in catastrophic flood disasters in metropolitan areas considering the distribution of mid–to-high-rise buildings in neighborhood. We assumed that not small number of residents would start evacuation when flood inundation was indeed imminent. We use GIS to calculate the potential death toll etc. during a catastrophic flood disaster considering the location, the number of stories, and the floor space of each building etc. We applied the method to a river, and found that it was important to consider the distribution of mid-to-high-rise buildings in neighborhood when developing and examining specific lifesaving countermeasures against extreme condition in catastrophic flood disasters.
