Abstract

This present study conducted the impact of the restoration of low-flow channel on fish habitat in a reach of the Wonju Stream, Korea. The target species were Zacco koreanus, a dominant species in the middle- and upper-stream of Wonju Stream. The River2D model was used for the computation of the flow and the habitat suitability index model was used to estimate the quantity and quality of fish habitat using habitat suitability curves. In order to restore the study area, the low-flow channel was identified through the bankfull discharge of the study reach, and the best hydraulic section was designed. In addition, various restoration techniques were applied to the low-flow channel through rocks, pool/riffle structures, and the change of the channel width. Simulation results indicated that the restoration of the best hydraulic section effects decreased habitat suitability for the target species. However, when various restoration techniques were applied, the WUA (Weighted Usable Area) was improved by about 11%.

본 연구는 저수로 물길 복원 조성을 통한 복원이 어류 서식처에 미치는 영향을 파악하기 위하여 원주천을 대상으로 물리서식처 분석을 수행하였다. 대상 어종은 원주천 중･상류에 서식하는 우점종인 참갈겨니를 대상으로 하였다. 흐름 분석은 2차원 모형인 River2D 모형을 사용하였으며, 서식처 분석은 서식처 적합도 곡선을 이용하여 서식처의 양과 질을 산정하는 서식처 적합도 모형을 사용하였다. 먼저 저수로 복원을 위하여 대상 구간의 강턱유량을 통하여 저수로 물길을 확인하고, 이를 통해 수리학적으로 유리한 저수로 단면을 설계하였다. 또한, 저수로 구간에 거석, 여울/소 구조, 그리고 단면 확폭을 통하여 다양한 복원기법을 적용하였다. 그 결과 수리학적으로 유리한 저수로 물길 복원 조성의 경우 현상태의 하폭보다 감소하였기 때문에 서식처가 악화되는 것으로 나타났다. 그러나 다양한 복원 기법을 적용하였을 때 서식처는 약 11% 정도 향상되는 것으로 나타났다.
