  • The Saemangeum master plan includes dredging and waterproofing materials, construction projects that can change the hydraulic characteristics of the Saemangeum and Mangyeong and Dongjin River basins. In this study, the river safety of 2030 when the Saemangeum master plan was completed for 100 year frequency, 500 year frequency and 100 year frequency applied RCP 8.5 scenario was examined using Delft3D. As a result of the analysis, it was confirmed that there was no overflowing point at the 100 year frequency, but the difference between the flood level and the river bank elevation was relatively small at the curved and river joint part. At the 100-year frequency with the 500-year frequency and the RCP 8.5 scenario, the possibility of overflowing at several locations was confirmed. The possibility of river bed loss due to fast velocity appears in the upstream part of Mankyung River and it is necessary to monitor the safety of hydraulic structures continuously. In addition, it is expected that the expansion of the area showing the characteristics of the lake due to dredging will affect the sediment mechanism and water quality, so detailed and diverse studies will be needed.

  • The "Master Plan for the Revitalization of Water in the Nakdong River" is designed for the fundamental improvement of water quality in the Nakdong River. The water quality and flow of the Nakdong River system tributaries was monitored in this study. Among the living environmental standard parameters of 195 rivers, BOD (Biochemical oxygen demand), T-P (Total phosphorus) and TOC (Total organic carbon) were assessed to analyze the water quality from 2012 to 2019. We examined the role of TOC. It was found that 12 rivers exceeded the water quality of the second grade (3.0 mg/L BOD standard, 0.1 mg/L T-P standard, 4.0 mg/L TOC standard) based on BOD and T-P concentrations: the Gumi stream, Gisegok stream, Yongha stream, Yongho stream, Changnyeong stream, Gajwa stream, Gwangok stream, Yeongsan stream, Toerae stream, Hwapo stream, Sangnam stream and Hogye stream. These rivers require strategies to improve the quality of the Nakdong River. Based on the ongoing project, it is possible to supplement the "Master Plan for the Revitalization of Water in the Nakdong River" and manage it after verifying it as a component of people's life and therefore used to establish water quality control measures.

  • 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.

  • This study was conducted to performance appraisal of Total Maximum Daily Loads (TMDLs), especially in terms of performance on development & reduction plan and water quality status of unit watershed. Because load allocations for pollution sources were predicted redundantly by uncertainty of prediction, TMDLs master plan has been frequently changed to acquire load allocation for local development. Therefore, It need to be developed more resonable prediction techniques of water pollution sources to preventing the frequent change. It is suggested that the reduction amount have to be distributed properly during the planning period. In other words, it has not to be concentrated on the specific year (especially final year of the planning period). The reason why, if the reduction amount concentrate on the final year of the planning period, allotment loading amount could not be achieved in some cases (e.g., insufficiency of budget, extension of construction duration). If the development plan was developed including uncertain developments, it is necessary to be developed reduction plan considered with them. However, some of the plans in the reduction plan could not be accomplished in some case. Because, it is not considered financial abilities of local governments. Consequently, development plan must be accomplished to avoid uncertain developments, and to consider financial assistance to support the implementation of effective plan. Water quality has been improved in many unit watersheds due to the TMDLs, especially in geum river and yeongsang/seomjin river.
