Abstract

Squr dikes in rivers can enhance various ecological environments, contributing to the improvement of the river’s environmental functions. However, the alterations in flow caused by squr dikes not only enhance environmental functions but can also have adverse effects. Therefore, this study aimed to analyze the flow changes induced by the installation of squr dikes through flume experiments and assess their impact on fish habitats. Key factors in the fish habitat environment include flow velocity, turbulence kinetic energy, and recirculation zones. Among these, particular emphasis was placed on examining turbulence kinetic energy and recirculation zones. Experimental conditions were set by varying the interval and submergence of the squr dikes, resulting in a total of eight experimental cases. The results revealed that shorter interval and lower submergence of the squr dikes led to increased turbulence kinetic energy and recirculation zone sizes, significantly impacting fish habitats.

수제는 하천 내에서 다양한 생태환경을 제공할 수 있어 하천의 환경 기능을 향상시키는 데 활용될 수 있다. 그러나 수제로 인해 변화하는 흐름이 환경 기능을 향상시키는 것만은 아니며, 부정적인 영향을 초래할 수 있다. 따라서 본 연구에서는 수리실험을 통해 수제의 설치로 인한 흐름변화를 분석하여, 어류서식처에 미치는 영향을 검토하였다. 어류의 서식환경의 주요 인자로는 유속, 난류운동에너지 및 재순환영역 등이 있으며, 그 중 난류운동에너지와 재순환영역을 중점적으로 검토하였다. 수제의 간격과 잠김정도를 실험조건으로 설정하여 총 8가지 케이스에서의 실험을 수행하였으며, 실험결과 수제의 간격이 짧고, 잠김정도가 낮을수록 난류운동에너지와 재순환영역의 크기가 증가하여 어류서식처에 미치는 영향이 크게 나타났다.
