The Korean government is developing a systematic plan of integrated coastal management for effective conservation, utilization, and development of coastal areas. For this plan, integrated maps of land maps and nautical charts are indispensable. However, these maps are not made, nor studied yet in terms of integration, although digital maps(DM) on land and electronic nautical charts(ENC) have been recently developed by Korean Geography Institute and National Marine Investigation Institute, respectively. In this study, as preliminary studies to make eventual integrated maps, the concept of coastal areas are defined, specifically, coastal lines from DM and ENC are matched against each other. Issues on map production procedures, coordinate systems, and map projections, are carefully considered. A test coastal area located in Seo-Gu, Pusan, over 14 km of coastal lines is selected for the edge matching of coastal lines. RMS differences are 13.83 m and 4.37 m over man-made coastal lines and natural coast lines, respectively, which are quite larger considering a scale difference and other factors. However, no systematic differences are found.

Coastal Zone is a integrated space including both coastal waters and inland. C.Z.M is a strategic practice system which can integrate and coordinate the coastal zone for preserving and making use of coastal resources. Through foreign and domestic C.Z.M Cases, this study analyzes the operating mechanism in the three aspects: role sharing among the administrative agencies, mediation and cooperation among the interested parties, and inducements of voluntary participation. And it achieves the common characteristics of C.Z.M: building the assessment system for establishing desirable policy directions, the stable support system for sustainable coastal management, the mediation system for cooperation of stakeholder, and the education system for reinforcing the management ability and inducing the voluntary participation. Finally it suggests the implications to build the coastal zone management system properly on the basis of common values in this mechanism.

The optimal water allocation pursues a reliable and economic supply of water resources to meet various interests in socio-economic-environmental aspects. The global water shortage has intensified due to climate change and population growth with limited water resources. Thus, the water management scheme has shifted to improve water use efficiency by proper demand management and water allocation planning. Here, a hydro-economic water allocation model, called WAMM (Water Allocation and Management Model) is introduced. The WAMM is equipped with an improved linear programming algorithm for optimal water allocation and estimates economic value of water supply as an objective of water

지하수개발 이용의 허가시 지하수 양수로 인한 주변지역에 미치는 영향을 조사하여 지하수의 고갈과 오염을 예측하고 이를 사전에 방지함으로써 지하수의 보전과 합리적인 이용을 도모하고자 지하수영향조사제도가 시행되어 왔다. 특히 하천구역의 경계로부터 300미터 내의 지역에서 지하수를 개발 이용하는 경우에는 지하수영향조사서를 첨부하여 국토해양부장관과 미리 협의하도록 되어있고, 이 때 지하수개발 이용이 하천의 수량에 영향을 미친다고 인정하는 경우에는 취수량 취수 기간의 제한 및 취수 금지 등을 요청할 수 있다. 그러나, 하천인근의 지하수 양수가 하천수에 미치는 영향을 정량적으로 평가할 수 있는 기법이 마련되어있지 않아 실무적으로 지하수영향조사 및 허가 절차상 어려움을 겪고 있다. 따라서 본 연구에서는 지하수 이용에 따른 하천수량 변화를 예측할 수 있는 간편 상관관계식을 지표수-지하수 통합모의 결과를 이용하여 유도 제시하였다. 지표수-지하수 통합모의를 위해서 SWAT-MODFLOW 결합모형을 적용하였고, 두 개의 시험유역에 대해 가상의 양수정 설치에 따른 하천수량 변화량을 평가하는 시나리오 분석을 수행하였다. 상관관계는 다중회귀분석을 통해서 하천수 감소량을 지하수 양수량, 하천과 양수정 이격거리, 대수층 및 하천바닥의 수리전도특성, 강수량 등의 함수로 나타내었다.

The purpose of this study is to establish an effective protection and management system for World Heritage (WH) nomination of Southwestern Coast Tidal Flat (SCTF) by proposing a model of protection and management. SCTF has a potential to become a representative best practice to achieve a sustainable development for human society. SCTF has a potential Outstanding Universal Values (OUVs) for WH nomination, thus a harmony between human and nature for wise use of natural resources needs to be pursued. It is required to present the system of SCTF's protection and management and to analyze present status of the regions in the Tentative List by comparing the case which were already inscribed as WH. For better protection of nominated areas, SCTF should expand an area for protection with additional designation. For the management system, two separate management systems such as the Department of Culture & Tourism and the Department of Oceans & Fisheries need to be reconciled. Because of this overlapping management structure, the management of the nominated sites has been inefficient and long-term management plan is lacking. Therefore, it is necessary to integrate conflicting management system of each local government and make a long-term, integrated management plan. To make an efficient and sustainable protection and management, it is essential to set up a collaboration system by integrating various stakeholders such as central and local governments, academic organizations, local residents, and NGOs. As in the case of Wadden Sea, the combined community system of the stakeholders mentioned above should be established. Because it is essential for local residents to understand a basic concepts for protection and management, it is necessary to establish capacity-building of local people. The protection and management structure should be set up by bottom-up processes, that is the proper structure shoud be based on thorough research on local society as well as thorough communication with local residents to make relevant laws and policies. This study also propose the proper plan for better conservation and management of SCTF.

Recently, as the extreme drought continued due to the reckless development and the dramatical climate change, national concern about the water management issues has been increased rapidly around the world, especially in Korea. Meanwhile, it is necessary to analyze and review the related cases in Australia, where they have developed the consistently, eco-friendly and systematically management from the national level, which is similar to that of Korea in difficult circumstances. Australia has been suffered by repeated droughts and floods due to low rainfall and dryness, and water disputes were begun with immigrant settlement in the 1890s. In the early days, water management agreements for efficient distribution of water resources, water use regulation programs, and federal water laws were enacted, and now the established water management system in which development and conservation are assumed to be well balanced. In Korea, however, in the past, the Ministry of Environment was responsible for water quality issues while the quantity was managed by the Ministry of Land, Infrastructure and Transport, and the main local departments for water management were divided. Therefore, it was difficult to manage the integrated water management due to problems such as duplicated works, excessive investments, and inefficiency. To resolve this situation, in 2018, all water management functions were unified, such as enacting the fundamental water-related laws, thereby laying the foundation for the integrated water management system for each basin. From 2019, even the integrated water management system was implemented, we are promoting the effect of sustainable water resource management. In order to establish a management policy for efficient and eco-friendly water management, the IWRM (Integrated Water Resource Management) of Australia, which has been devised in various ways, was analyzed and compared with the present situations and cases occurred in Korea, and the implications from this study would be suggested the future of IWRM in Korea.

Despite the increasing importance of urban parks' ecological functions in dealing with the climate crisis, ecological parks are not clearly defined in Korea's legal system. Numerous ecological parks created nationwide cannot be systematically designated and managed due to various legal bases and varying management authorities. It is important to clarify the legal status of ecological parks in order to lead the ecological paradigm shift of urban parks and to improve the natural park system for a comprehensive and integrated approach to protect the national ecosystem. To this end, related laws were analyzed to identify problems and to draw directions for legislative improvement. Through the literature review of relevant laws, acts, and ordinances, six major directions for improvement were suggested based on the analysis of problems. First, the legal status of ecological parks in the administrative dichotomy of the current park system is ambiguous, and ecological parks should be clarified through the revision of park-related laws. Second, an ecological park can be defined as a sustainable park created and managed in an ecological manner, promoting the protection and restoration of the ecosystem, conservation, and promotion of biodiversity, and balancing nature observation, ecological learning, and leisure activities. Third, the role of the state and local governments should be systematically revised to lead to a new park planning and management model through new governance. Fourth, since the characteristics of ecological parks are affected by individual laws, the possibility of overlapping ecological parks for other uses should be allowed. Fifth, detailed guidelines and standard ordinances need to be enacted to meet the goals, principles, and facilities of ecological parks. Lastly, along with the revision of the laws, ordinances by local governments also need to be more concrete. This study, which tracks various legal realities related to ecological parks, can contribute to policymaking that can systematize the foundation for the creation of ecological parks to preserve nationwide ecosystems and provide citizens with opportunities to experience and learn about nature.
