Abstract

In order to reduce flood damages, there should demand an appropriate design such as enlarging a bank, dredging a river bottom, building a hydraulic structure and so on. The installation locations about the Watergate are listed of the seven provisions in the river design standard, but it is not detailed. In order to compute proper place considering landuse and basin characteristics of inlands, internal inundation modeling that should be performed is regarded with quantitative evaluation. Anyway, that is very complex and taking a long time because that has to consider hydraulic and hydrologic characteristics. In the current study, therefore, the simple and convenient method for internal inundation modeling was proposed to overview the Watergate location.

본 홍수피해를 저감하기 위해 하천의 제방 증축, 하도준설, 수리구조물의 설치 등에 있어 적합한 설계가 요구된다. 이 중에서 배수문에 관한 하천설계기준을 살펴보면 설치위치는 7개의 항목으로 나열되어 있으나, 그 기준이 상세하지 않음을 알 수 있다. 제내지의 토지이용 및 유역특성을 반영한 배수문의 적절한 위치를 산정하기 위하여 외수위를 고려한 내수침수모의가 수행되어 정량적 평가가 이뤄져야 한다. 그러나 내수침수모의는 대개 수리 수문학적 특성을 동시에 고려해야 되기 때문에 매우 복잡하고 시간이 오래 소요된다. 따라서, 본 연구에서는 배수문 설치에 대한 정량적 검토를 바탕으로 간편하고 정확한 설계방법을 제시하였다.
