Abstract

This study investigated the impact of abandoned channel restoration on fish habitat using the physical habitat simulation. The study area is a 1.2 km long reach of the Cheongmi-cheon stream. In the study area, the restoration of the abandoned channel was carried out from July 2012 to December 2105. Physical habitat simulations were carried out for both cases before and after the restoration. The River2D model and habitat suitability curve were used for hydraulic and habitat simulations, respectively. Zacco platypus, which is a dominant fish species in the study area, was selected as target fish for the physical habitat simulation. Hydraulic simulations were carried out before and after restoration for various discharges. Then, composite suitability index and weighted usable area were calculated before and after restoration and changes in the physical habitat of Zacco platypus were discussed. Simulation results indicated that the abandoned channel restoration is effective in creating fish habitat and mitigating the degradation of fish habitat from the high flow condition.

본 연구에서는 물리서식처 분석을 이용하여 구하도 복원에 따른 어류서식처의 영향을 분석하였다. 연구대상지역은 청미천의 1.2 km 구간이다. 연구 대상 지역에서 구하도 복원은 2012년 7월 부터 2015년 12월 까지 수행되었다. 복원 전과 후에 대하여 물리서식처 분석을 실시하였다. 이때, 수리해석을 River2D 모형을 이용하였으며 서식처분석을 위하여 서식처 적합도 지수 곡선을 이용하였다. 대상어종은 연구대상지역의 우점종인 피라미를 선정하였다. 복원 전과 후의 조건에 대하여 다양한 유량에 대하여 수리해석을 실시하였다. 이후 구하도가 복원 되기 전과 후의 조건에서 복합 서식처 적합도 지수와 가중가용면적을 계산하였으며, 피라미의 물리서식처 변화에 대하여 분석하였다. 모의 결과 구하도가 복원될 경우 어류의 서식처 영역이 증가되었으며, 큰 유량에 대하여 서식처의 감소를 방지하는데 효과가 있음을 확인하였다.
