Since 1960s urban streams in Seoul have been dried and polluted because of urbanization. So, these devastated urban stream environment need to be restored for the better life of residents. Since 1995 stream restoration project which is called Natural-Style Stream Project have begun. However, some projects focused on the restoration of park-style open space rather than restoration of stream environment. As a result there are some stream landscapes to be improved. Therefore, this study aims to investigate the current status of urban stream landscape after Natural Style Stream Project and to propose the alternatives for the urban stream landscape improvement. The study site is Yangjae stream, Seoul.

In Germany has a long history of ecological restoration and restoration management. At the beginning of the 1990s, the "Erfolgskontrolle" was used as an evaluation program after the restoration project and many exchanges of views took place. It is the time, in Korea, there is a need for a comprehensive evaluation program after the restoration project, as there is no evaluation method yet. At this time it may be the "Erfolgskontrolle" in Germany as a practical model for the Korean restoration management program. The purpose of this study is to identify the concept and character of the "Erfolgskontrolle" and to demonstrate the implication and potential of application, through the analysis of the implementation example of the revaluation of river revitalization. To achieve the goal was carried out theoretical and 3 exemplary revitalization research cases. And it was endeavored to deliver the German way of acting and the basic idea to Korea. For the restoration, the "precautionary principle" should be considered first, the upper legal regulation should not be violated. In order to apply "Erfolgskontrolle" in practice, the goal formulation should be clear and systematically evaluated. And through the collection of typified cases, the comprehensive and unified theory should be established, it is possible, thus the qualitative assessment of the restoration project.

Urban stream restoration projects can improve water quality, wildlife habitats, urban landscape, outdoor recreation spaces, and urban microclimate. The objectives of this research were to investigate temperature cooling effect of urban streams by using satellite imagery, to evaluate environmental variables related to stream cooling effect, and to estimate the cooling effect of the Cheonggye stream restoration project of Seoul, Korea. Findings of this research can be summarized as follows. First, a method of estimating temperature distribution around urban streams by using satellite imagery was developed. Scatter plots of distance from stream edges and average temperature obtained through multiple buffering were used for the estimation. Second, urban temperature cooling effect of streams was estimated by comparing background temperature and temperature of each buffer zone. Third, environmental factors affecting stream cooling effect were also identified. Fourth, the temperature cooling effect of the restoration project was estimated based on three scenarios. An estimated cooling effect based on the average cooling effect of existing tributaries showed the most significant effect; $2.0^{\circ}C$ lower than the present level at the edge of the renovated stream. It was estimated that the temperature of the same area would be $1.4^{\circ}C$ cooler than the present level if the cooling effect of the Yangjaechun was used as the bench mark But the effect would be $1.2^{\circ}C$ lower than the present level if environmental variables related to the temperature cooling effect of urban streams were used as the bench mark.
