초록

지금까지 추진해 오던 제외지 중심의 하천복원에서 벗어나 최근에는 제내지까지 복원하고자 하는 노력이 시도되고 있다. 이의 일환으로 구하도의 복원이 추진되고 있으나 이로 인한 수리적 연결성 및 생태적 연결성 향상을 정량적으로 평가할 적합한 모형의 개발은 미진한 상태이다. 본 연구에서는 구하도 복원을 통한 생태적 연결성 회복을 평가할 수 있는 격자기반의 수리해석 모형을 개발하였다. 본 모형의 적용성을 검토하기 위하여 노탑리 일원의 청미천 하천복원 사업지를 대상으로 수리생태적 연결성을 평가하였다. 본 모형으로 수리 및 생태적 특성의 시 공간적 분포를 신속하고 간단하게 해석할 수 있었으며 향후 수리적 생태적 연결성을 평가하는 적절한 도구로 활용될 수 있을 것으로 판단된다.

Beyond river restoration focused on the inside region of main streams up to now, the river restoration including the outside region of streams has been started recently. As a part of this attempt, the restoration of abandoned rivers has been tried, but the development of a suitable model to quantitatively assess the improvement of hydraulic and ecological connectivity is not still satisfying. In this study, a grid - based hydraulic analysis model to evaluate the recovery of ecological connectivity through the restoration of abandoned rivers has been developed. In order to examine the applicability of this model, the ecohydaulic connectivity of the Cheongmi River Project area in Notap region was evaluated. This model can promptly and simply analyze the temporal and spatial distribution of the hydraulic and ecological characteristics, and it can be used as a appropriate tool to assess the hydraulic and ecological connectivity in the future.
