초록

국립재난안전연구원의 재난안전 신기술 공적개발원조(ODA) 사업의 일환으로 2019년 라오스 볼리캄싸이주 남싼강유역의 보리칸을 대상으로 홍수예경보시스템을 구축하였다. 미계측 중소하천유역인 대상 지역에 강우량와 유출량의 실시간 관측을 위한 관측소 및 경보국을 설치하였으며, 실시간 자료 관리와 홍수예경보 기능 등을 수행하는 소프트웨어도 개발되었다. 홍수경보 기준 설정 및 홍수예측을 위한 nomograph 개발을 위해 대상 지역의 30년 치 연도별 최대 일강우량자료와 하천측량성과를 바탕으로 수리·수문분석을 수행하였다. 본 논문은 시스템 구축 과정과 방법론을 소개하고, 시스템 설치 후 2020년 실시간 관측 수집된 자료들을 바탕으로 수행한 시스템의 적용성 검토 결과를 제시하였다.

As part of the National Disaster Management Research Institute's Official Development Assistance (ODA) projects for transferring new technologies in the field of disaster-safety management, a flood forecasting and warning system was established in 2019 targeting the Borikhan in the Namxan River Basin in Bolikhamxai Province, Laos. In the target area, which is an ungauged small and medium river basin, observation stations for real-time monitoring of rainfall and runoff and alarm stations were installed, and a software that performs real-time data management and flood forecasting and warning functions was also developed. In order to establish a flood warning standard and develop a nomograph for flood prediction, hydraulic and hydrological analysis was performed based on the 30-year annual maximum daily rainfall data and river morphology survey results in the target area. This paper introduces the process and methodology used in this study, and presents the results of the system's applicability review based on the data observed and collected in 2020 after system installation.
