Development of Science-Based Decision Support System for Evaluating the Safety of Evacuation Facilities in Case of Torrential Rains

Abstract

Torrential rains have been increasing in frequency. There have been instances in which residents were caught up on their way to evacuation shelters. It is important to check on hazards caused by conditions, on the adequacy of evacuation facilities, and on water levels and weather advisories. When taking appropriate action in torrential rains, it is necessary to assess weather and water information based on the preliminary survey of evacuation. To improve the quality of decision making, a science-based procedure should utilized by public agencies to judge the situation. We propose a procedure manual and web-based system for take appropriate action as disaster response.
