Water disasters such as flash floods and inundation caused by localized heavy rainfall in urban areas have a large impact on climate change but are also closely related to the increase in impervious areas as pointed out in domestic and international studies. It is difficult to secure natural green areas in urban areas that have already been developed. So, urban regeneration can be expected using water management optimized with technologies to secure infiltration and storage capacity such as Low-Impact Development technology. In this study, the water cycle improvement ability was confirmed by applying the LID technology within the district unit plan of the environmentally friendly village, and the economic feasibility of LID application was analyzed by estimating the costs and benefits of installing the facilities. The site was planned to conserve sufficient green and plans for securing the watershed infiltration and storage capacity were formulated with the application of additional LID technology, such as infiltration trenches, rain barrels and permeable pavements. The LID design method applicable to the site was established, and the water balance of the watershed was analyzed through simulations of the SWMM model. The water circulation improvement effect was confirmed through the water balance analysis, and the cost-benefits were determined according to the estimation method, and the economic analysis was conducted. This study confirms that the investment of LID technology is economically feasible for the hydrological improvement effect of the housing complex.

Analysis of fish farm influences on stream water quality may provide basic informations on watershed management to reduce environmental impact due to fish farm development and to conserve stream water quality in forested watershed area. In this research stream water qualities around Mt. Baegun area were monitored seasonally for three years. Due to the increase of pH in effluent water from the fish farm it was believed that alkalization of stream water can be accelerated by large scale development of fish farms in the forested watershed area. As a result of regression analyses, the linear equation of pH of influent and effluent water of fish farm was, pH of effluent water of fish farm = $0.6234{\times}pH$ of influent water of fish farm + 2.6263. Also, the linear equation of electrical conductivity of influent and effluent water of fish farm was electrical conductivity of effluent water of fish farm = $1.7275{\times}$electrical conductivity of influent water of fish farm - 14.007. Negative effects on stream water quality were observed by indications of increase in electrical conductivity and water temperature of effluent water from the fish farm. Decreases in physicochemical indices such as the amount of dissolved oxygen, total amount of cation and total amount of anion in effluent water from the fish farm were also negative aspects in downstream ecology. It is recommended that water purification system as well as environmentally-friendly fish farm design should be incorporated to large scale fish farm development plan in forested watershed area.

This study aims at establishing an ecological planning for road construction. which is considered to be a main cause of damage to the natural environment in Korea. This study focuses on the Pyungtak-Eumsung Highway development project. It considers the ecological factors and status of the site and its surrounding area. The study site is a four-way highway with a width of 23.4m and a length of 5.7km that spans from Hyungok-ri, Anseong City, Kyeonggi Province to Jukhyun-ri, Jincheon-gun, Chungbuk Province. The objective of the plan is "the establishment of an eco-road in harmony with nature." The plan is divided into five detailed goals: 1) restoration of river morphology and ecosystem through ecological planning; 2) establishment of wet biotopes; 3) construction of ecological corridors; 4) restoration of damaged forest ecosystems; and 5) ecological restoration of the roadside slopes that are linked with the surrounding forest. A master plan has been developed based on the detailed goals. The master plan involves: 1) establishment of a natural river, wet biotopes, and ecological corridors that facilitate the movement of amphibians, wild fowls, mammalians and fish; 2) development of a planting plan for the visitor center, the tunnel entrance, and soundproof banks; and 3) the presentation of a planting model for restoring roadside slopes that are connected to the surrounding forest. The eco-road plan needs to entail ecological conservation and restoration plans. In addition, a monitoring plan for ecological corridors and habitats should be included in the comprehensive plans, along with the continuous development of environmentally friendly technologies.
