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.
