Abstract

Urban flooding due to rapid urbanization has recently become frequent. In this study, a hydraulic model experiment was conducted on Shinwol rainwater storage and drainage system constructed for the first time in South Korea to prevent urban flooding. Experiments were preformed for 55 scenarios, of which 19 overflows occurred. In addition, the video analysis for the scenarios where the overflow occurred showd that the overflow occurred during the process of exhausting the pressurized air in the facility and the undular bore were moving. Results of this study, it was judge that it would be advantageous to maintain a completely drained or full-pipe condition for stable operation of the Shinwol rainwater storage and drainage system for continuous rainfall in the future. And it is necessary to additional research on the correlation for the magnitude of inflow discharge, overflow and undular bore.

급격한 도시화로 인한 도시홍수가 최근 들어 자주 발생하고 있다. 본 연구에서는 도시홍수를 방어하기 위해 국내최초로 건설중인 신월 빗물저류배수시설을 대상으로 수리모형실험을 실시하였다. 총 55가지 시나리오에 대한 실험을 실시하였는데 그 중 19가지 시나리오에서 월류가 발생하였다. 또한 월류가 발생한 시나리오에 대한 비디오 분석결과, 불규칙 단파가 이동하면서 시설 내 압축공기를 배기시키는 과정에 월류가 발생하는 것으로 분석되었다. 본 연구 결과를 바탕으로 향후 연속강우에 대한 신월 빗물저류배수시설에 대한 안정적 운영을 위해서 완전배수 또는 만관상태를 유지하는 것이 유리할 것으로 판단되고 유입유량의 크기, 월류, 불규칙 단파간의 상관관계에 대한 추가 연구가 필요할 것으로 판단된다.
