Abstract
In this study, the flow in the spillway of Gun-nam flood control reservoir were simulated by using FLOW-3D model. The discharge in the overflow weir and flow stability in approach channel were investigated with the original design plan. The results show that the scale of spillway is unsuitable and the flow in approach channel is unstable. To solve this problem, therefore, the alternative design plan were formulated. The flow in the spillway were simulated with the alternative design plan. The results show that the scale of spillway is suitable and the flow in approach channel is stable.
Key Words: Flood control channel; FLOW-3D model; Spillway; Approach channel
요지
본 연구에서는 군남 홍수조절지 여수로의 흐름을 FLOW-3D 모형을 이용하여 모의하였다. 기본계획안에 따라, 월류웨어의 방류능력과 접근수로의 안정성을 검토한 결과 여수로 규모가 적절하지 못하고, 접근수로 내의 흐름은 불안정한 것으로 나타났다. 그래서, 문제점올 해결하기 위한 개선안을 마련하였다. 개선안에 따라 여수로의 흐름을 모의하고, 월류웨어의 방류능력과 접근수로의 안정성을 검토하였다. 그 결과 개선된 여수로의 규모는 적정한 것으로 나타났고, 접근수로의 안정성은 향상되는 것으로 나타났다.
핵심용어: 홍수조절지; FLOW-3D 모형; 여수로; 접근수로
