isotopic composition is significantly lighter on average composition of river water and is close to the values of melted glacier water. During spring, snowmelt by the processes of infiltration, underground reservoirs are accumulated melt water and at dry periods turn to sources of runoff formation of river. Of course, it will affect the isotopic composition of river water [20].

Now the priority areas for the Central Asian countries are water and the effects of climate warming. The continued degradation of mountain glaciations, growing rate of population in the region and the problem of water supply of the population and economy branches have stimulated the search of scientific mechanisms, approaches to sustainable development at the national level and the solution to the problem of conflict-free use of water resources of

Integrated water resources management can play a key role in reducing tensions and conflicts between upstream and downstream countries of Transboundary Rivers of Central Asia on water issues, biodiversity and ecology of rivers and the rational use of water resources in the region. Certainly, the degree of implementation and effectiveness of integrated water resources management is mainly determined by the availability of reliable meteorological, hydrological and glaciological information and the degree of interchange between the countries of the region. High-level saturation of climatic information is achieved only at a continuous and
