This study analyzed the management plan of Seomjin River Chimsil Wetland by identifying landscape changes through aerial photographs analysis and concentrations of sedimentation. Geophysical Landscape Change Analysis showed that vegetation accounts for more than half of the total area. The Barren land and water body was somewhere repeatedly increased and decreased and made an irregular form in the study area. The soil was acidic, and no eurtophication was shown, but it was potential to form wetland. In addition, the research area has been terrestrification of sand bar for a long period of time, forming a soil layer. Although the characteristics of river deposits were shown in the study area, the grain size was a particulate matter, and the sorting was 'very poorly sorted'. In some areas of Seomjin River Chimsil Wetland, sand bars were formed, but most areas were undergoing to terrestrification. Therefore, in order to preserve the riverine area and to serve by a bridge between the land ecosystem and the underwater ecosystem, it is very necessary to remove some vegetation, create a proper waterway, and restore the wetland.

In 2007, London Thames Gateway delivery plan was started, and it was in progress to solve climate change, population density, housing problems, green space, regional imbalances, and transportation issues from east London and Kent to Essex. The plan was carried out faithfully local autonomy enlargement of local governments. This case is evaluated as a successful case of waterfront regeneration with well balanced on development and conservation. This study concludes as follows by comparing with this case and a new Han River management foundation plan. First, Seoul's new plan needs to change to diffuse thinking on comprehensively understanding. Second, local and central government, which are adjacent to Han River, need management scheme in cooperation. Third, the countermeasures for solving traffic problems in Seoul are required through the provision of transportation method to take advantage of the waterfront.

Korean-Chinese is one of the 56 minority groups in the People's Republic of China. Korean-Chinese is the same origin as the Korean Peninsula. In the mid of 19th century, they, who lived in a part of Joseon, suffered with nature disasters and poverty, therefore they offended against the law, immigrated, and started farming in Ching Dynasty, which is northeast China in the present. Later, Korean's individual and mass migrations were happened around coastland of Tumen River and Yalu River with the connivance of the law. This thesis is a consideration of how the Korean-Chinese has adapted before and after the liberation from Japanese colonial era to the Chinese socialism and What their Residential Plan Composition and Plan Types in the village. Based on the field research and literature research, introduces the village history, Plan Composition and sample Plan types. Then, Based on this research, it will be the foundation of the future study of the Korean-Chinese's villages and planning study to conserve the villages.

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.

The effect of seasonality on water quality variation is very significant. Generally, it reduce the power of the trend extraction. A parametric time-series model was used for detecting trends in historic constituent concentration data. The effect of seasonality is able to remove from time series decomposition technique. According to such statistic methode, long-term water quality trend analysis system (NTrend 1.0) was developed by Nakdong River Water Environmental Research Center. The trend analysis of BOD variation was conducted with NTrend 1.0 at Goreong and Moolkum site in Nakdong river to show the effect of water quality management action plan. Power test of trend extraction was tried each case of 'deseasonalized and deannulized' data and 'deseasonalized' data. Analysis period was from 1989 to 2006, and it's period was divided again three times, 1989~1993, 1994~1999 and 2000~2006 according to action plan period. The BOD trend was downward in Goreong site during three times and it's trend slope was very steep, and upward in Moolkum during 1989~1993, but it was turned downward during 1994~1999 and 2000~2006. It was revealed that it's very effective to reduce the concentration of BOD by water quality management action plan in that watershed. The result of power test was shown that it is high for trend extraction power in case of 'deseasonalized' data.

This study was performed to analyze the effects of a water circulation green area plan on non-point source pollution in Gimhae South Korea. A quantitative analysis of Arc-GIS data was conducted by applying a watershed model based on Fortran to investigate the changes to direct runoff and pollution load. Results showed that prior to the implementation of the water circulation green area plan in Gimhae, direct runoff was $444.05m^3/year$, total biological oxygen demand (BOD) pollution load was 21,696 kg/year, and total phosphorus (TP) pollution load was 1,743 kg/year. Implementation of the development plan was found to reduce direct runoff by 2.27%, BOD pollution load by 1.16% and TP pollution load by 0.19% annually. The reduction in direct runoff and non-point source pollution were attributed to improvements in the design of impermeable layers within the city.

Recently severe drought caused the water shortage around the western parts of Chungcheongnamdo province, South Korea. A Diversion tunnel from the Geum river to the Boryong dam, which is the water supply dam for these areas has been proposed to solve this problem. This study examined hydraulic impacts on the Geum river associated with the diversion plan assuming the severe drought condition of 2015 would persist for the simulation period of 2016. The hydraulic simulation model was verified using hydrologic and hydraulic data including hourly discharges of the Geum river and its 8 tributaries, fluctuation of tidal level at the mouth of the river, withdrawals and return flows and operation records of the Geum river barrage since Feb. 1, 2015 through May 31, 2015. For the upstream boundary condition of the Geum river predicted inflow series using the nonlinear regression equation for 2015 discharge data was used. In order to estimate the effects of uncertainty in inflow prediction to the results total four inflow series consisting of upper limit flow, expected flow, lower limit flow and instream flow were used to examine hydraulic impacts of the diversion plan. The simulation showed that in cases of upper limit and expected flows there would be no problem in taking water from the Geum river mouth with a minimum water surface level of EL(+) 1.44 m. Meanwhile, the simulation also showed that in cases of lower limit flow and instream flow there would be some problems not only in taking water for water supply from the mouth of the Geum river but also operating the diversion facility itself with minimum water surface levels of EL(+) 0.94, 0.72, 0.43, and 0.14 m for the lower limit flow without/with diversion and the instream flow without/with diversion, respectively.
