Abstract

Fishways are essential structures that must be installed in rivers to facilitate the movement of fish between upstream and downstream areas. However, the efficiency of fish passage varies depending on the flow conditions within the fishway. Therefore, this study examined the fish-friendly flow characteristics within a stepped fishway at different overflow depths using FLOW-3D, and conducted experiments for model validation. The key parameters affecting fish swimming ability include velocity, turbulent kinetic energy, and energy dissipation rate. These factors were assessed using a simulated fish species, the zacco platypus, to evaluate the suitability of fish-friendly flow condition. It was confirmed that overflow depth significantly influences fish behavior, and an appropriate overflow depth is required for stepped fishway design. The results of this study are expected to serve as fundamental data for the design of stepped fishways in the future.

하천에서는 어류의 상·하류 간의 이동을 위해 어도는 필수적으로 설치해야 하는 시설이다. 그러나 어도 내부의 흐름에 따라 이동효율의 차이가 발생한다. 따라서 본 연구에서는 FLOW-3D를 통해 월류수심에 따른 계단식 어도 내의 어류 친화적 흐름을 검토하였고, 모형을 검증하기 위해 개수로 실험을 수행하였다. 본 연구에서는 어류의 유영능력에 영향을 미치는 주요 항목으로는 유속, 난류운동에너지, 에너지소산율 등이 있으며, 이와 같은 항목으로 대상 어류를 피라미로 가정하여 어류 친화적 흐름의 적합성을 판단하였다. 월류 수심은 피라미에게 유효한 영향을 끼치는 것을 확인할 수 있었으며, 어도의 낙차에 따라 적합한 월류수심이 요구된다. 향후, 본 연구결과는 계단식 어도 설계의 기초자료가 될 수 있을 것이라 기대된다.
