It is necessary to draw up many plans to solve problems in the management of groundwater resources in Jeju Island while systematically develop and utilize water resources at an optimal level. It also seems to an evitable option to establish Groundwater Management Areas in Jeju Island. The excess use of groundwater could be discouraged by imposing charges on those licenses. Such policy as allowance trading system do not appear to be because of transaction costs, but could be applied if only were accompanied by complementary method. The methods of using and conserving the limited resources of groundwater should be founded through socially agreeable and appropriate ways. The policy complemented allowance trading system by Pigouian tax could be effective to regulate licenses. This is cutting the numbers of licenses at a constant rate, imposing charges on those who want to continue using licenses, and reimbursing in cash to those who return the licenses.

지하수는 한번 오염되면 원상복구가 어렵고 피해가 장기적으로 나타날 수 있으므로 그 관리가 아주 중요하다. 지하수 오염관리를 위해서는 오염 현황파악과 공간적 확산예측이 필수적이며, 이를 위해서는 GIS를 이용한 체계적인 분석이 필요하다. 따라서 지하수의 과학적 관리를 위해서는 다양한 지하수 자료들의 체계적인 데이터베이스구축이 필수적이며, 이를 기반으로 지하수관리정보시스템에서 오염현황이 분석된후 지하수업무와 직접 연계, 활용되어야 한다. 금번연구는 이러한 배경속에서 서울시 지하수관리를 위해 구축된 지하수관리 통합시스템의 전문분석 서브시스템을 이용하여 중구 일부지역을 대상으로 질산성질소(NO3N)의 오염확산을 분석한후 축척 1/5,000 오염확산예측도가 작성되었다. ´96년 서울시에서는 기초조사시 1/25,000 수문지질도를 작성하였으나 이 자료로는 지역적 지하수 오염관리가 어려우며, 금번연구를 통하여 작성된 대축적 분석도면들의 활용이 기대된다. 본 연구를 위해서 사용된 GIS시스템은 Arc/Infor, Are/View이며, 지하수분석을 위해서는 MODFLOW, MT3D가 이용되었다.

Rural groundwater monitoring network has been managed by Korea Rural Community Corporation (KRC) since 1998. The network consists of two kinds of subnetworks; rural groundwater management network (RGMN) and seawater intrusion monitoring network (SIMN). RGMN has been operated to promote a sound and sustainable development of rural groundwater within the concerned area for groundwater quality and quantity. SIMN has been operated to protect the crops against hazards by the saline water in coastal areas in which the shortage of irrigation water become a main problem for agriculture. Currently, a total of 283 monitoring wells has been installed; 147 wells in 79 municipalities for RGMN and 136 wells in 52 ones for SIMN, respectively. Two subnetworks commonly monitor three hydrophysical properties (groundwater level, temperature, and electric conductivity) every hour. Monitored data are automatically transferred to the management center located in KRC. Data are opened to the public throughout website named to be the Rural Groundwater Net (www.groundwater.or.kr). Annual reports involving well logging and hydrochemical data of RGMN and SIMN have been published and distributed to the rural water management office of each municipalities. In addition, anyone who concerns about RGMN an SIMN can freely download these reports throughout the Rural Groundwater Net as well.

GIS is linked with Numerical Model(PM5) for the effective conservation and management of groundwater resources. All the relevant system was systematically constructed to analyze the field status by means of precise understanding of the surface and subsurface environment and by accumulating large amounts data and attribute data into developed system. The necessity of integrated management of the groundwater information was demonstrated and the general direction of the construction of groundwater management system was suggested. The proposed system will guide a method for the rational decisions of groundwater development via the establishment of the appropriate database management and accurate prediction of future change.

In this study, we suggested the management scheme of analyzing the national and oversea related policy against soil and groundwater contamination by radioactive materials due to nuclear accidents. In Korea, we need to remedy swiftly the contaminated land due to intensive land development demand. So, we need to develop more effective management scheme to recover actively the land contaminated by radioactive materials. We require to improve monitoring network, to expand media-specific monitoring system, to prepare management system for remediation of contaminated land, and to develop flow work for soil and groundwater remediation.

Groundwater is our invaluable asset because it takes action in the case of climates changes like drought or floods. But the Korean government has formulated water-resource policies mostly focused on surface water. As a result, the groundwater that will be more important resource in the future has been treated carelessly, caused neglect of maintenance and resulted many abandoned wells. This poor management of groundwater is because of lack of organization on our asset, manpower, unclearness of managing body, shoddy construction and lack of supervision. In order to solve this problem, we need a special agency of groundwater that contribute people's awareness by promotion importance of groundwater, dissemination of technical education and professionals. To do that, we have to establish a specific groundwater management plan based on regional characteristics of watersheds and specialized institution need to promote responsible development and usage in groundwater.

Rapid development of geophysical exploration and hydrogeologic monitoring techniques has yielded remarkable increase of datasets related to groundwater systems. Increased number of datasets contribute to understanding of general aquifer characteristics such as groundwater yield and flow, but understanding of complex heterogenous aquifers system is still a challenging task. Recently, applications of data science technique have become popular in the fields of geophysical explorations and monitoring, and such attempts are also extended in the groundwater field. This work reviewed current status and advancement in utilization of data science in groundwater field. The application of data science techniques facilitates effective and realistic analyses of aquifer system, and allows accurate prediction of aquifer system change in response to extreme climate events. Due to such benefits, data science techniques have become an effective tool to establish more sustainable groundwater management systems. It is expected that the techniques will further strengthen the theoretical framework in groundwater management to cope with upcoming challenges and limitations.

Global climate changes affect the local hydrologic cycle, and subsequently, require changes in water resource management strategies of Korea. Variations in precipitation and urbanization have adverse effects on the reasonable and efficient utilization of groundwater resources. Groundwater management strategies of Korea have been implemented based on the evaluation of "sustainable yield", which is calculated from the amount of annual recharge. However, this sustainable yield has no consideration of natural discharge and dynamic equilibrium of the groundwater system. Therefore, for the effective groundwater management strategies of the following decades, we need representative and reliable observations, and have to develop methods for the systematic analysis and interpretations of the data to draw valid information in linkage of natural and societal environmental changes.
