Abstract

This study was conducted to evaluate the impact of weir gate operation in aquatic fish habitats through a physical habitat simulation of Geum River, Korea. The target species was Zacco platypus, which is a dominant species in the study area. The River2D model was used to compute the flow, and the habitat suitability index model was used to estimate the quality and quantity of the habitat using a habitat suitability curve. An unopened case and a partially opened case were investigated to assess the impact of weir gate operation on the aquatic fish habitat. The simulation results showed that the aquatic habitats of the target species in the partially opened case improved significantly, compared to the case without a gate opening. Furthermore, the weighted usable area increased by a factor of approximately 13, owing to weir gate operation in the study area.

본 연구는 다기능 보의 수문 운영 여부에 따라 수생 서식처의 변화를 파악하기 위하여 물리서식처 분석을 수행하였다. 대상 구간은 금강이며, 대상 어종은 피라미를 대상으로 하였다. 흐름 분석은 2차원 모형인 River2D 모형을 사용하였으며, 서식처 분석은 서식처 적합도 곡선을 이용하여 서식처의 양과 질을 산정하는 서식처 적합도 모형을 사용하였다. 수문 개방 여부에 따라 서식처의 변화를 살펴보기 위하여 수문 미개방과 부분개방에 대하여 설정하였다. 그 결과 수문을 부분개방하였을 때 현상태 대비 가중가용면적이 약 13배 향상되는 것으로 나타났다.
