정구열,Jeong, Gu-Yeol 한국방재협회 2013 방재저널 Vol.15 No.2

최근 기상이변으로 가뭄과 홍수, 폭설 등 자연재난이 전 세계적으로 빈번하게 발생하고 있고, 우리나라도 예외는 아니어서 일 강수량이 300mm가 넘는 집중폭우의 횟수도 증가하고 있다. 특히 지난 해 한반도 지역의 아열대성 기후변화로 인해 잦은 국지성 폭우와 태풍 등 물재해로 인명과 재산피해가 점증하고 있다. 2012년 7월에 발생한 제7호 태풍 '카눈'을 시작으로 잇따른 초대형 태풍 '덴빈', '볼라벤', '산바'는 태풍이 북상하여 중부지방 중심 전국적으로 많은 비를 내렸으며 경기 및 강원 북부 일부 지방은 관측 강우량을 경신하였다. 홍수기 시 수자원 운영에 미치는 댐, 보 수문자료의 활용을 통해 홍수분석 등에 활용됨으로써 홍수분석 의사결정 시 신속하게 대응할 수 있는 물 관리 시스템에 대한 요구가 높아지고 있는 실정이다. 이에 K-water에서는 최신 ICT 기술을 융합한 "실시간 수자원정보시스템"을 구축 운영하여 24시간 365일 상시 모니터링함으로써, 2012년에 과거 유래 없는 4개의 대형 태풍이 한반도에 상륙하였을 때에도 안정적으로 시스템을 운영하면서 신속하게 대응할 수 있었다.
