Ecological restoration of rivers and wetlands with a Sustainable Structured wetland Biotope (SSB) system

Byeon, Chan-Woo

Abstract Based on technologies applied to upper and lower parts of the Kyeongan stream and to a river in Gwanggyo New Town in Korea, new methodologies for ecological restoration, ecological water quality improvement, and water-friendly landscape of wetlands and rivers were introduced, as well as theoretical, practical and institutional restraints. Then some strategies for overcoming restraints were proposed. For a successful implementation of ecological restoration of the river and wetland, the following factors should be considered. First, an approach of ecological restoration should be taken in consideration of natural features which are site-specific to the region. Second, the ecological restoration of a river should be done according to the principles of ecological and environmental engineering. Third, the entire process of restoration, which includes planning, design, construction and maintenance, should be monitored according to ecological and environmental guidelines; quantitative data regarding the effectiveness of water purification and of ecological restoration should be continuously collected through monitoring. Fourth, civil engineering, landscape architecture, environment, ecology, art and design should be combined multidisciplinarily. Fifth, it is urgent to develop legal and institutional frameworks as well as a variety of practical guidelines and manuals regarding ecological restoration that fits site-specific characteristics.
