A sudy on the management and utilization of the saetgang stream in the Hangang river(Ⅰ)
With the reduction of ecological spaces in urban area, the public’s interest in the urban water environment has grown. Despite their importance, however, urban small rivers including the Saetgang Stream are being abandoned. The Saetgang Stream means a branch river in Korean and by definition, “a branch river is led off from the main river and joined by an alluvial island” that plays an important role in providing habitat for biodiversity. For that reason, the Saetgang Stream in Yeouido can be a politically representative example of the management and revitalization of urban small rivers. In this study, we investigated the specific areas of waterway structure, water quality, odor and ecological monitoring to identify Saetgang Stream’s environmental condition. In addition, current status and issues were analyzed through literature review, interviews with responsible public officials and local community committee members and by accepting expert opinions.
In this context, the aim of this study is firstly to investigate the ecological environment and the use and management of the Saetgang Stream, then to provide implications and improvement suggestions in the first year of the two-year study.
