Description

<p>During heavy rainfall disasters, quantitative assessments of disaster risk are necessary to support municipalities' decision to issue evacuation information and residents' decision on whether to evacuate has been noted. In this research, two disaster risk assessment methods are proposed for municipalities and residents, based on the evacuation time. Afterwards, in a flood scenario of Joso City, the lead-time of municipalities' evacuation decisions has been calculated by the municipality-oriented assessment method. Meanwhile, the temporal variation of evacuation difficulty of each resident has been quantified by resident-oriented assessment method. As a result, the proposed methods have been considered feasible to support the evacuation decisions of municipalities and residents.</p>
