Abstract

This study analyzed the aspect of bed change according to the stable channel design on the Wonju River to quantitatively evaluate habitat suitability (HS). According to the result of evaluating stable channel of object section in the Wonju River, 17 sections among total 20 sections were stable and 3 sections were unstable. Physical disturbance improvement evaluation (PDIE) was the range average showed good disturbance condition with a range average of 112.17 points. Habitat suitability index of Zacco Koreanus, the most dominant species of the Wonju River, was used for analysis of physical habitat for fish. According to the physical habitat analysis result, HS was 0.16 and weighted usable area (WUA) was 347.68 m2. The methods of improving/introducing/removing structures and dredging stream channel were used for stable channel design of unstable channel, and analyzed PDIE according to the aspect of bed change and changes in habitat suitability. Stable channel design was possible in 19 sections in times of structures improvement/introduction/removal, and PDIE was 117.53 points, HS was 0.14 points, and WUA was 313.37 m2. Stable channel design was possible in all 20 sections when dredging the stream channel. PDIE was 116.50 points, HS was 0.16, and WUA was 332.14 m2. Therefore, this study obtained channel design measures that can improve physical soundness and stability of the Wonju River, and it was analyzed that it will have no impact on changes of physical disturbance and physical habitat. Furthermore, this study analyzed velocity and depth of each section and appearance frequency of riffle and pool to analyze correlation between physical disturbance and physical habitat. According to the analysis result, it was identified that the analysis of riffle and pool showed similar result as the evaluation result of physical habitat.

본 연구는 원주천을 대상으로 안정하도 설계에 따른 하상변동 양상을 분석하여 물리적 교란과 서식적합도 (Habitat suitability, HS)를 정량적으로 평가하였다. 현재의 원주천 대상구간에 대한 안정하도 평가 결과 총 20개 구간 중 17개 구간이 안정하였으며, 3개 구간이 불안정한 것으로 나타났다. 물리적 교란개선 평가 (Physical disturbance improvement evaluation, PDIE) 결과 구간평균 112.17점으로 현재 양호한 교란개선 상태를 나타냈다. 어류의 물리서식처 분석은 원주천의 최우점종인 참갈겨니의 서식적합지수를 이용하였다. 물리서식처 분석 결과 HS는 0.16, 가중가용면적 (Weighted usable area, WUA)은 347.68 m2으로 나타났다. 불안정 하도의 안정하도 설계를 위해서 시설물의 개선·도입·철거와 하도를 준설하는 방법을 이용하였으며, 하상변동 양상에 따른 PDIE와 서식적합도의 변화를 분석하였다. 시설물의 개선·도입·철거 시 19개 구간에서 안정하도 설계가 가능하였으며, PDIE는 117.53점,HS는 0.14, WUA는 313.37 m2로 나타났다. 하도의 준설 시 20개 전구간에서 안정하도 설계가 가능하였다. PDIE는 116.50점으로 나타났으며, HS는 0.16, WUA는 332.14 m2으로 나타났다. 따라서 원주천의 물리적 건전성과 안정성을 제고할 수 있는 하도설계 방안을 도출하였으며, 그에 따른 물리적 교란과 물리서식처의 변화는 영향이 없을 것으로 분석되었다. 아울러 물리적 교란과 물리서식처의 상관 분석을 위해 구간별 유속과 수심 및 여울과 소의 출현 빈도를 분석하였다. 분석 결과 여울과 소의 분석은 물리서식처의 평가 결과와 유사하게 나타남을 확인하였다.
