Heavy Rain Damage Prediction Considering Regional Disaster Prevention Budget

Abstract

Many researches are conducted to evaluate benefit from local disaster prevention projects. However, since such evaluation can only be assessed at the local district level, there is a limitation to applying this assessment to the local government's disaster prevention management in that it requires the local characteristics. To compensate for this, in this study, the effect of disaster damage reduction through local governments’ local disaster prevention budget was estimated, and that used for disaster damage reduction in the area was calculated. Further, the effect was applied to the damage prediction model that is typical local government-level disaster prevention management, and heavy rain damage prediction was done considering the effect. As a result of applying it to the study area, the effect was prominent in Pyeongtaek-si and Pocheon-si in Gyeonggi-do. Also, considering the results of the effect, it was confirmed that error in the heavy rain damage prediction function was reduced. The results of this study can be used to establish disaster prevention budget management and disaster mitigation plans.
