Abstract

The purpose of this study is to develop and apply a river space restoration framework considering various functions of river basin system. In particular, we will present sustainable river basin management directions by quantifying the effect of improving the aquatic ecosystem through the restoration of river space. For this purpose, the present problems are derived from functional aspects of the river basin, and the river area restoration framework linked with the individual outcome indicators is constructed to evaluate the restoration effect by each function. The ecological impact of restoration of river area was quantitatively analyzed by introducing ecotope concept. As a result of the comparison of restoration effects by creating three kinds of river area restoration scenarios, the construction of suitable habitat such as backswamp in the expanded area has shown favorable results in expanding biodiversity. The diversity evaluation of ecotope in conjunction with the hydraulic and hydrological characteristics of the year will not only provide the expected effects of restoration of river space but will also serve as a criterion about post-project monitoring for outcome evaluation.

본 논문의 목적은 하천유역시스템의 다양한 기능을 고려한 하천공간 복원 프레임워크를 개발하고 적용하는 것이다. 특히, 하천공간 복원을 통한 수생태계 개선 효과를 정량화함으로써 지속가능한 하천유역관리 방향을 제시하고자 한다. 이를 위하여 하천유역의 기능 측면에서 현재의 문제점을 도출하고, 각 기능별 복원효과 평가를 위해 개별 성과지표와 연계한 하천공간 복원 프레임워크를 구축하였다. 하천공간 복원에 따른 생태적 영향은 에코톱 개념을 도입하여 개선효과를 정량적으로 분석하였다. 3가지 하천공간 복원 시나리오를 작성하여 복원 효과를 비교분석한 결과, 확대되는 공간에 배후습지 등 적절한 서식처를 조성하는 것이 생물다양성 확대에 유리한 결과를 나타내었다. 연중 수리 수문 특성과 연계한 에코톱의 다양성 평가는 하천공간 복원의 기대효과를 제시할 뿐만 아니라 성과평가를 위한 사업 후 모니터링의 기준이 될 것이다.
