Abstract

It is very important to decide probability precipitation that is used as hydraulic structure design and target rainfall for urban disaster prevention. Especially, National Emergency Management Agency (NAMA) announced target rainfall from probability precipitation in korea on city and district level. It make use to performance evaluation of disaster prevention and planning of development for disasters prevention capacity target. In this study was calculated target rainfall that is duration 1~3 hour based unit of gu (borough) by point and regional frequency analysis using rainfall data of Surface Synoptic Stations (SSS) and Automatic Weather Stations (AWS). The result of this study can utilized as a reference to related business such as disaster capability assessment and achievement of prevention capacity target against disasters. And it also will be contribute to establishment of prevention capacity target against disasters.

확률강우량은 수공구조물 설계와 도시방재를 위한 기준 등으로 활용되고 있어, 확률강우량의 산정은 매우 중요하다. 특히 소방방재청에서는 확률강우량으로 우리나라 시 군 단위로 지역방재성능목표를 설정하고 이에 대한 방재성능평가 및 방재성능목표 달성을 위한 개발계획 수립 시 활용하고 있다. 본 연구에서는 현재 시 군 단위로 설정되어 있는 목표 강우량을 구(區) 단위로 산정하고자 기상청의 지상기상관측지점(SSS, Surface Synoptic Stations)과 방재기상관측지점(AWS, Automatic Weather Stations)의 강우자료를 활용하여 지점빈도해석 및 지수홍수법을 이용한 지역빈도해석을 통해 지속시간 1시간, 2시간, 3시간 목표강우량을 산정하였다. 이는 서울지역의 지자체별 방재성능 평가 및 방재관련 업무에 참고자료로 활용할 수 있을 것으로 판단되며, 향후 방재성능목표 설정에 크게 기여할 것으로 판단된다.
