초록
홍수 도달시간의 예측은 하천의 수량 관리와 운영 측면에서 매우 중요하다. 최근에는 다기능보의 건설로 수문환경이변화하였기 때문에 운영조건에 따라 하류부에 미치는 영향이 상이할 것으로 예상되어 정밀한 홍수파 도달시간의 산정이필요한 시점이다. 이에 본 연구에서는 영산강을 대상으로 2차원 해석이 가능한 HEC-RASver5.0.3 모형을 적용하여 주요지점의 홍수파 도달시간을 분석하고자 하였다. 분석 결과, 주요 지점의 방류량 증가와 하류부 운영조건에 따른 홍수파도달시간의 비선형적인 특성을 재현하였다. 본 연구 결과를 활용한다면, 하천 운영에 도움이 될 것으로 기대한다.
Abstract
Forecasting of flood wave travel time is very important in terms of river management and operation. Recently, the hydrological environment of has changed due to the construction of multi-function weir in the river. It is necessary to analyze flood wave travel time, including hydraulic structures in the channel. The flood wave travel time according to the discharge and downstream water level operating conditions was analyzed using HEC-RASver5.0.3 which is capable a two-dimentional analysis. This study showed nonlinear characteristics of flood wave travel times due to increase of discharge and operating conditions. The results of this study will be helpful for the operation of multi-function weir as well as the river operation.
