최근의 유역통합관리는 용수공급, 수력발전, 그리고 유지용수 등과 같은 기존의 운영방안과 더불어 수량, 수질, 생태계 보호를 함께 고려해야만 하는 등 운영목적이 복잡해지고 시스템 또한 대규모화 되고 있다. 더불어 용수이용 혹은 유역간 서로 상충되는 이해관계가 발생함에 따라 물이용의 효율성을 극대화할 수 있는 범 유역 단위의 수자원 계획 및 운영이 필요하게 되었다. 최적화 모형의 현실 활용 기회를 높이고, 수자원관리의 다양한 운영목적을 수자원 운영에 반영하기 위하여 본 연구에서는 저수지 운영률을 개발하고 이를 적용하기 위한 KModSim의 수문학적상태방법에 대한 적용성을 검토하였다. 본 연구에서 개발된 운영률은 전체적으로 용담댐과 대청댐의 실적저류량을 잘 재현하는 것으로 나타났으며, 이를 최적화 모형에 활용한다면 관행적으로 적용해온 물수지 분석 방법을 개선할 뿐만 아니라 유역통합수자원관리가 가능할 것으로 기대된다.

수자원개발의 한계와 수질의 오염으로 인해 제한된 수자원을 효율적으로 이용하고 수질을 보전하기 위한 통합수자원관리가 절실히 요구되는 상황이다. 최근 이를 위해 수자원을 통합적으로 평가하여 계획의 수립을 지원할 수 있는 통합수자원평가계획모형(K-WEAP)을 개발하였다. 본 연구에서는 3가지 부문에서 K-WEAP의 적용성을 평가하였다. 첫째는 수자원장기종합계획에 적용한 K-WEAP의 물 수급 전망 과정과 분석결과를 통하여 수자원 계획의 도구로서 K-WEAP의 유용성을 제시하였다. 둘째는 K-WEAP에서 제공하는 지표수-지하수 연계모의를 통해 보다 합리적이고 지속가능한 지하수이용 계획을 제시하였다. 마지막으로, K-WEAP의 수질모의 신뢰성을 평가하기 위하여 석화천을 대상으로 QUAL2E 모형의 결과와 비교하여 수량-수질 통합관리평가의 기능을 확인하였다.

This research presents a prototype development and implementation of Decision Support System (DSS) for integrated river basin water management for the flood control. The DSS consists of Relational Database Management System, Hydrologic Data Monitoring System, Spatial Analysis Module, Spatial and Temporal Analysis for Rainfall Event Tool, Flood Forecasting Module, Real-Time Operation of Multi Reservoir System, and Dialog Module with Graphical User Interface and Graphic Display Systems. The developed DSS provides an automated process of alternative evaluation and selection within a flexible, fully integrated, interactive, centered relational database management system in a user-friendly computer environment. The river basin decision-maker for the flood control should expect that she or he could manage the flood events more effectively by fully grasping the hydrologic situation throughout the basin.

Korean agriculture experienced rapid changes in its production structure to respond fluctuations on external conditions, and these changes have increased the dependence between agricultural resources and negative environmental externalities from agricultural production. As a tool for managing agricultural resources and reducing negative environmental effects from agricultural production, this study employs water-energy-food nexus for integrated resource management. To show the necessity of an integrated approach, this study evaluated three policy scenarios including changes in capital interest, water capacity, and energy cost. The results show that three scenarios have unintended consequences for farmers' incomes and their use of resources. Also the unintended consequences of government policies also affected farms' vulnerability to environmental changes. In particular, the expansion of financing for the establishment of non-circulating water curtain facilities did not have a significant effect on the crop switching of farms. In addition, increasing the amount of available water through the aquifer recharge project leads to the installation of non-circulating water curtain facilities in zucchini farm. It raises dependence on groundwater in agricultural production, thereby increasing farmers' vulnerability to groundwater shortages. These results imply that the agricultural sector needs to consider the interrelationship between agricultural resources when designing or evaluating policies.

A project constructing sewerage facilities in 9 upstream areas of 7 multi-purpose dams will have been completed by 2011. After all constructing and retrofitting of the new and the existing sewerage facilities, integrated management system with operation and control functions for the each levels of facilities will also be utilized. In this study, we studied how to compose the organization taking responsibility of the integrated management system and analysed human resources saving effect against conventional method of individual management of each sewerage facility. As a result, a method estimating the human resources in employing the integrated management among several sewerage facilities at upstream areas of dams were presented and some 23% of human resources could be saved by integrated management. Commissioning to a specialized public institute showed the highest B/C ratio of 4.5 among commissioning to local public corporations, commissioning to private corporations, and role-sharing partnership, etc.

수자원관리의 패러다임은 기존의 댐 위주에서 모든 수계를 종합적으로 분석하여, 수량, 수질, 방재 등을 종합적으로 분석하고 관리하는 쪽으로 변화하고 있다. K-water는 4대강 및 다목적댐 등을 위주로 하는 유역통합물관리가 실현되고 있으며, 이러한 수자원 통합관리를 위한 정보통신시스템은 사용자 중심의 수도 발전 댐 관리 등을 전자적으로 수행할 수 있도록 구축되어 있다. 정보통신시스템을 구성하는 제어시스템은 설비의 동작을 관리 제어하는 시스템으로 하부 센서 및 필드에서 수집된 데이터를 바탕으로 정보를 저장하고, 원격에서 설비를 제어하는 기능을 하고 있다. 따라서 본 논문에서는 댐 보등 수자원분야의 통합관리를 위한 정보통신시스템 구축방안에 대해 알아보고 최적의 시스템 구축방안 및 시스템의 보안취약부분에 대해 알아보고자 한다.

The Se San and Srepok river basins (2S) are the two major tributaries of the Mekong River, both of which originate in the territory of Viet Nam and flow to Cambodia to meet at Stung treng with the Sekong river (originating in Lao PDR) to form the 3S river basin before joining the Mekong mainstream. In the territory of Viet Nam, the 2S river basins are located in the Central Highlands including 5 provinces, arranged by geographical location from north to south namely Kon Tum, Gia Lai, Dak Lak, Dak Nong and Lam Dong. This is a region with a very important strategic position in terms of economy, politics and defense for the whole country with many potential advantages for economic development. However, the limited and vulnerable basin water resources are under the pressure of socio-economic development in line with increasing water demands for various sectors. In order to overcome the water management challenges, a long-term water resources planning has conducted to support the 2S River Basin Committee (RBC) in effective planning and operation as part of the WB Mekong-Integrated Water Resources Management (IWRM) Project. This paper introduces the outline and progress of the river basin planning using analytical DSS toolkits to analyze, evaluate and formulate the planning options.

Active attention and effort are needed to develop an integrated water management system in response to climate change. In this study, it proposed models for cross-use of agricultural water and river maintenance water using sewage treatment water as an integrated water management system for the Yeongsan River. The impact of the integrated water management models was assessed by applying the concept of Nexus, which is being presented worldwide for sustainable resource management. The target year was set for 2030 and quantitatively analyzed water, energy, land use and carbon emissions and resource availability index by integrated water management models was calculated by applying maximum usable amount by resource. An integrated water management system evaluation model using the Nexus concept developed in this study can play a role that can be viewed in a variety of ways: security and environmental impact assessment of other resources. The results of this research will be used as a foundation for the field of in the establishment of a policy decision support system to evaluate various security policies, as we analyzed changes in other factors according to changes in individual components, taking into account the associations between water, energy, food, and carbon resources. In future studies, additional sub-models need to be built that can be applied flexibly to changes in the future timing of the inter-resource relationship components.
