초록

본 연구에서는 하상변동의 고려가 물리서식처 모의에 미치는 영향을 검토하였다. 이를 위해 수리 및 이동상 계산은 CCHE2D 모형을 이용하였으며 서식처 적합도 곡선을 사용하여 서식처 평가를 실시하였다. 적용구간은 달천 유역 괴산댐 하류 수전교에서 대수보까지 약 2.5km 구간이며, 2006년 7월 홍수기 시 실측된 유량 및 수위자료를 이용하여 이동상 모의를 수행하였다. 수치모형의 검증은 실측된 수위와의 비교를 통해 수행되었으며 하상변동의 검증은 실시 하지 않았다. 물리서식처 분석은 우점종인 성어기 피라미를 대상으로 실시하였다. 고정상과 이동상 조건에서 각각 갈수량, 저수량, 평수량, 풍수량의 유랑조건에 대한 복합서식처 적합도 지수 분포를 모의하고 가중가용면적을 산정하였다. 모의 결과, 이동상 조건에서 모의구간의 상류 및 만곡부에서 복합 서식처 적합도지수가 상승하는 결과를 확인하였다. 또한 가중가용면적은 이동상 고려 시 5.4~11.3%정도 증가하는 것을 확인하였다.

This study investigates the impact of morphological change on the physical habitat simulation. For this, CCHE2D model is used for the hydraulic analysis including the morphological change, and the physical habitat suitability is assessed with habitat suitability curves. The model is applied to a 2.5km long reach downstream of the Goesan Dam, from Sujeon Bridge to Daesu Weir. Flow data of discharge and stage in July, 2006 are used in the computation. The numerical model is verified by means of comparison with the measured water surface elevation data, and the variation of the river bed is not verified in this study. Adult Zacco platypus is chosen for the dominant species. Physical habitat simulations result in composite habitat suitability and weighted usable area for drought, low, normal, and averaged-wet flows. The simulation results indicate that the composite suitability index increased at reaches right downstream of the Sujeon Bridge and around the bend. This also increased weighted usable area by 5.4-11.3%.
