SWMM 모형을 이용한 지하저류조 유입부 횡월류웨어의 적정 규모 분석 = An Analysis on the Optimal Inlet Side-Weir Size of Underground Storage Facility Using SWMM

다국어 초록 (Multilingual Abstract)

Recently, lots of underground storage facility have been constructed in order to protect the flood damage in urban area and in general, the inlet of underground storage facility is installed by side-weir. An analysis on change of overflow discharge and storage volume due to the inlet side-weir size of underground storage facility is essential in order to enhance the effect of inundation prevention and the secure operation of the underground storage facility. In this study, inundation analyses in drainage districts of Seoul city, Mokpo city and Changwon city where had been encountered flood damages in past were carried out by using the Storm Water Management Model(SWMM) and a reasonable design capacity of each underground storage facility was calculated by overflow disposal options of the SWMM. Also, the optimal inlet side-weir size of underground storage facility which be able to minimize to a volume of designed storage space as well as to resolve the inundation problem of urban areas was analyzed as considering size of pipeline.

최근 도시지역의 내수침수를 방지하기 위해 지하저류조의 설치가 늘어나고 있다. 일반적으로 지하저류조의 유입부로 횡월류웨어를 이용하는데 지하저류조의 침수방지 효과를 높이면서 지하저류조를 보다 안전하게 운영하기 위해서는 횡월류웨어의 폭과 함께 웨어의 높이 변화에 따른 월류량 및 저류용량 변화에 대한 연구가 필요하다. 본 연구에서는 SWMM 모형의 월류수 처리조건들을 이용하여 과거 침수가 발생하였던 서울, 목포, 창원의 3개 배수분구에 대해 침수분석을 실시하고 지하저류조 설치 시 적정 설계용량을 산정하였다. 또한, 도시침수를 해소하면서 주어진 설계저류공간의 저류용량을 최소화 할 수 있는 횡월류웨어의 적정 규모를 산정하였다.
