Changes of a climate have generated in territory of Ukraine and other countries of the world many various problems, among them reduction humidifying reservoirs of many rivers is marked also. Existing measures on management of a water management in connection with influence of change of a climate are obviously insufficient, about what is spoken and in some documents WMO. In given work on the basis of the analysis of components of water balance of territory the list of actions on regulation dry up reservoirs of the rivers which has arisen in connection with changes of a climate is spent. For the analysis the atmospheric precipitation measured for the long-term period, evaporation from a surface of ground and water, stocks of productive moisture in ground, a layer of a runoff of water are used. Reduction of a river drain on hydrological to a post Sluch – Sarny occurs due to reduction of soil inflow, and, decreases not only a component of a soil feed of the river, but also stocks of water in a soil layer 0-100 see. As the actions adjusting humidifying of territory, are recommended: restoration of marsh files, construction of small dams in the top parts of a hydrographic network beams and hollows, agrarian and wood land improvement. For maintenance of an ecological runoff in the river Dnepr regulation of outflow of water to Black sea system of sluices of available water basins is recommended.
