Abstract

In recent years, the possibility of flooding due to the increase in the incidence of high-frequency rainfall due to abnormal rainfall and the increase in concentrated torrential rain is increasing. Also, the amount of rainwater runoff is increasing due to the increase of the impermeable layer in the city due to the concentration of population due to urbanization and concentration of development. Due to the characteristics of the developed city, it is located in the vicinity of rivers and in the lowlands. For the analysis of inundation in water, using XP-SWMM, which can analyze stormwater pipelines and surface flows, and FLO-2D models that can track flood-sluice curves and rainfall-spill curves, based on hydraulic and hydrological analysis. Inundation analysis was conducted and comparative review was conducted. The patterns of flooding of the two models were compared, and a model suitable for domestic flooding was selected.

최근 이상강우에 따른 고빈도 강우 발생율의 증가 및 집중호우의 증가로 인한 침수발생 가능성이 증가하고 있다. 또한 도시화로 인한 인구집중과 개발 집중으로 인한 도시의 불투수층의 증가로 우수유출량이 증가하고 있다. 도시가 발달한 지역 특성상 하천 주변 및 저지대지역에 위치하고 있다. 내수침수분석에는 수리·수문분석을 바탕으로 우수관로 및 지표흐름 분석이 가능한 XP-SWMM 과 홍수-수문곡선과 강우-유출곡선을 추적 할 수 있는 FLO-2D 모형을 이용하여 실재 침수가 발생한 지역의 침수분석을 실시하여 비교 검토를 실시하였다. 두 모형의 침수발생 양상을 비교한 결과, 울진군 울진읍의 경우 LSSI 는 71.68%로 우수관망을 적용하지 않고 지형자료만을 이용한 FLO-2D도 양호하게 분석되었다. 따라서 XP-SWMM은 도시침수해소, 침수양상등 다양한 목적으로, FLO-2D는 침수양상만을 검토할 때 사용이 가능하다.
