This paper tells the story of trade-off between hydropower and irrigation and its implications for groundwater use in Syrdarya basin in Central Asia. With the independence of the central Asian republics, this trade-off has become a transboundary issue. Efforts to coordinate bilateral action using integrated water resources management (IWRM) principles of basin-wide cooperation have not yet yielded the hoped for results. This paper shows that there could be a 'second best' option of solving at least part of this transboundary problem by 'banking' winter flows released for hydropower production in Kyrgyzstan in the underground aquifers of Uzbekistan's Fergana Valley and extracting it for irrigation in the summer months
The publications in this series cover a wide range of subjects-from computer modeling to experience with water user associations-and vary in content from directly applicable research to more basic studies, on which applied work ultimately depends. Some research reports are narrowly focused, analytical and detailed empirical studies; others are wide-ranging and synthetic overviews of generic problems.Although most of the reports are published by IWMI staff and their collaborators, we welcome contributions from others. Each report is reviewed internally by IWMI staff, and by external reviewers. The reports are published and distributed both in hard copy and electronically (www.iwmi.org) and where possible all data and analyses will be available as separate downloadable files. Reports may be copied freely and cited with due acknowledgment.
About IWMIIWMI's mission is to improve the management of land and water resources for food, livelihoods and the environment. In serving this mission, IWMI concentrates on the integration of policies, technologies and management systems to achieve workable solutions to real problems-practical, relevant results in the field of irrigation and water and land resources.
In the researches has considered the principles of constructing a geo-information system based on modern GIS technologies, justified the boundary and initial conditions, developed a regional mathematical model of the Aydar-Arnasay Lake System (AALS) territory and implemented it on the basis of modern modeling programs Vizual Modflow for analyzing and assessing the dynamics of AALS development and its relationship with the components of the geological environment. The factors of groundwater formation are given and evaluated taking into account changes in water management conditions, their current state is highlighted and recommendations are given on substantiating the tasks of groundwater monitoring in these territories.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
