국문초록

2000년대 후반 이래로 홍수터를 활용한 생태공원이나 체육시설 등과 같은 다양한 친수시설들이 조성되었다. 또한 최근 강 우강도 및 홍수 빈도의 증가로 인해 관련 피해가 급증하고 있으며, 이는 홍수터에 설치된 공원과 같은 친수시설들의 침수 피해와 직접적으로 연관되므로, 극한강우 시 홍수터에서의 수치해석이 필요하다고 판단된다. 본 연구에서는 홍수터에서의 수위상승과 하강에 따른 수리학적 영향을 분석하기 위해 마름/젖음 모의가 가능한 준부정류 흐름해석모형인 FaSTMECH와 부정류 흐름해석모형인 Nays2D 모형을 이용하여 각 모델간의 태풍 사상시 시간에 따른 침수심 및 유속분포를 비교 분석 하였다. 태풍 사상시 홍수터에서의 유속분포는 주수로에서의 유속에 비해 매우 낮은 유속을 보이고 있었으며, 홍수터에서 는 침식보다는 토사퇴적 문제가 더 높을 것이라 판단된다.

영문초록

In the flood plain, river facilities such as sports facilities and ecological park are builded up since the late 2000s. The recent increase of rainfall intensity and flood frequency results in the immersions of parks and river facilities located in the flood plain. Therefore it is necessary to perform the numerical analysis for the extreme rain storm in the flood plain. In this study, to analyze the hydraulic impact by lowering and rising of the water level at flood plain, Both the FaSTMECH, which is a quasi-unsteady flow analysis model to be used for simulating the wet and dry, and the Nays2D, which is unsteady flow analysis model, are used in this study. Also, the flow velocity distribution and the inundation are compared over a period of the typhoon. As a result, the flow velocity distribution at flood plain showed very low values compared to the flow rate in the main channel. This means that the problem of sedimentation is more important than that of erosion in the flood plain.
