Based on water resources availability and development condition of the Lancang River, as well as considering the international river water resources characters, the paper put forwarded an integrated allocation way of the water resources of Lancang River Basin. According to the basic rules of equitable and suitable utilization of water resources of international rivers, water resources demand for domestic, industrial, irrigation and ecosystem system, and principles of society stabilities and the food safety etc, an index system of Lancang River water resources allocation was set up. Two levels scheme of Lancang River water allocation are proposed. First level is for an international water, which primarily to analysis the water quantity at the national boundary. Second level is for provincial water allocation among Qinghai, Yunnan provinces and Tibetan Autonomous Region. In the allocation schemes, the water resources development of Lancang River Basin at different scenarios and the related water allocation in different years and seasons were analyzed. A discharge to some cross sections of the river and a total amount water quantity for each district has been given as well.

This study explores methods of allocating costs incurring from construction of environmental infrastructure among local governments involved in the project. Principles for equitable cost-allocation are reviewed, and pros/cons associated with different methods are examined. Proportional Allocation method, Shapley Value method, SCRB (Separable Cost-Remaining Benefits) method are applied to a case of swage treatment plant in Gyeongnam province region, Korea. It is found that the SCRB method produces the most equitable result, followed by Shapley method. The Proportional Allocation method, although easy to understand and simple to calculate, is found to be skewed in favor of small town.

There are not many practical measures to solve a water conflict, when a hydromorphologically asymmetric situation in international rivers exists whereby downstream users may not affect upstream users but upstream users do cause downstream impacts. In taking advantage of this merit, North Korea has built Imnam Dam in upstream of North Han River and uses water for trans-basin hydropower generation. As an impact of this dam South Korean' area as a downstream user has been suffered from water deficit and dry river. It is very critical for South Korea to solve a key problem such as water allocation for water supply and river maintenance. Therefore, this study is aim to suggest alternatives for equitable water allocation in consideration of special circumstances between the South and the North. For this, reviewing the allocation methods of water rights is carried using lessons obtained from international river cases. The results show that the minimum desired streamflow is calculated at 7.3 $m^3/sec$; water budget analysis by the equitable distribution of streamflows at the border line of the North Han River, the difference in water supply deficiency is at 3.7 $m^3/sec$ before and after Imnam Dam; in the determined distribution method, the difference in water deficiency is at 11.38 $m^3/sec$. These results show that South Korea should be secured 11.38 $m^3/sec$ from North Korean's Imnam Dam in respective of water use right and sound river maintenance.

공유하천의 물 배분문제는 이해당사자간 입장차이가 뚜렷하여 일관된 해결책을 찾기가 어려운 과제이다. 따라서 문제해결을 위한 접근방법이나 적용하고자 하는 논리와 원칙이 일방적일 수 있으며, 연안국가간 서로 상반되는 논리를 주장하는 것이 대부분이다. 즉 어떤 국가든 자기에게 가장 유리한 입장을 취하게 되며 상대방의 주장에 동조하는 자세는 자국 내에서 큰 비판에 직면할 수 있다는 정치적 부담이 있다. 결국 각각의 연안국가들은 자기에게 가장 유리한 이론과 논리를 내세우게 되며 타협과 협력에 도달하기 위해서는 수문, 기상, 사회, 문화, 경제 및 정치적 문제를 극복해야 한다. 본 연구에서는 남북공유하천의 공평하고 합리적인 이용방법을 제시하기 위하여 이해관계가 복잡한 하류유역의 수리권을 추정하였다. 이를 위해 국제 공유하천에서 수리권 배분을 위한 표준화된 법칙이 없으므로 과거 사례 분석을 통해 해석방법을 찾고자 하였다. 아울러 현재 남북공유하천의 문제점을 진단하고 국제사례를 통해 하류국가인 남한지역에 기득수리권이 존재함을 증명하고자 하였다. 또한 수리권 배분(북한의 임남댐 보장방류량)을 위해 국제적으로 적용된 사례와 이의 평가기준 등을 고려하여 남북공유하천에 적용하고자 하였다.

New Zealand is a hydrologically diverse and active country. This paper presents an overview of the major hydrological issues and problems facing New Zealand and provides examples of some the research being undertaken to solve the problems. Fundamental to any environmental decision making is the provision of good quality hydrometric data. Reduced funding for the national hydrometric network has meant a reduction in the number of monitoring sites, the decision on how to redesign the network was made using information on geographic coverage and importance of each site. New Zealand faces a major problem in understanding the impacts of rapid land use change on water quantity and quality. On top of the land use change is overlain the issue of agricultural intensification. The transfer of knowledge about impacts of change at the small watershed scale to much larger, more complex watersheds is one that is attracting considerable research attention. There is a large amount of research currently being undertaken to understand the processes of water and nutrient movement through the vadose zone into groundwater and therefore understanding the time taken for leached nutrients to reach receiving water bodies. The largest water management issue of the past 5 years has been based around fair and equitable water allocation when there is increasing demand for irrigation water. Apart from policy research into market trading for water there has been research into water storage and transfer options and improving irrigation efficiency. The final water management issue discussed concerns the impacts of hydrological extremes (floods and droughts). This is of particular concern with predictions of climate change for New Zealand suggesting increased hydrological extremes. Research work has concentrated on producing predictive models. These have been both detailed inundation models using high quality LIDAR data and also flood models for the whole country based on a newly interpolated grid network of rainfall.
