Abstract: 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.

Abstract: The assessment of the accessibility of water in the basin and significance setting of its use is essential before planning for the expansion and development of additional sectors which poses pressure on water availability. The main purpose of this study was to evaluate the performance of SWAT model to simulate stream flow of Mojo River. The performance evaluation of the model was to obtain the water balances was conducted. In this study both secondary and primary data were used. The SWAT model was used for data analysis. In this study for stream flow yield simulation the parameters involving surface runoff (CN2.mgt) and ground water (ALPHA_BNK.rte was found to be the most sensitive parameters. A good agreement between observed and simulated discharge were observed, which was verified using both graphical technique and quantitative statistics. The value of R2=0.80, NSE=0.75, RSR=0.5 and PBIAS=-10.6 obtained during calibration and R2 value 0.76, NSE value 0.69, RSR value 0.56 and PBIAS -14.4 obtained during validation as well as the uniformly scatter points along the 1:1 line during calibration and validation justify that the model is very good in simulating observed steam flow. From the results the total annual surface water available yields is estimated around 0.401Billion Cubic Meters (BCM).
