A Study on Improvement of Target Setting Criteria for Disaster Prevention Performance in Jeju Island

Abstract

The government has set the disaster prevention performance target rainfall by the local government (National Emergency Management Agency, 2012) as a flood control policy that can prepare against natural disaster. However, the method of setting the disaster prevention performance target rainfall by municipalities does not reflect the rainfall characteristics of mountainous regions and islands. In this study, rainfall data reflecting the altitude and regional characteristics were analyzed using the meteorological observation system (ASOS, AWS) for Jeju Island. As a result, it was found that the rainfall increases about 1 ~ 4 times as the altitude increases from the lowland to the highland, and the existing disaster prevention performance target standard of Jeju Island does not reflect altitude characteristics. In addition, The target rainfall for disaster prevention performance is presented as dividing the two localities of Jeju city and Seogwipo city into Jeju East, West South and North areas. It is considered that various factors can be reflected in the compatibility assessment stage of rainfall estimation standard.
