ABSTRACT. - The Influence of climate changes on the water balance in the Western Bug River basin Kamianka Buzka. Quantitative indicators of water balance represent the ratio between the air and water components of the environment. Therefore, by analyzing the structure of water balance of the river basin, it is possible to estimate the local manifestations of the global climate change impact on the aquatic components. The main goal of this paper is to calculate and display water cycle process within the Western Bug River basin - city of Kamianka Buzka and to define its input-output elements. For this purpose the water balance equation of the catchment area was calculated monthly and yearly for climate normal and current periods and the general water balance equation was calculated for long-term (1961 - 2014) period. Meteorological components were determined as the weighted average for river basin, according to the observations at three meteorological stations. Compared to the climate normal period, the air temperature in the basin of the river Вug increased by 0.8C, which led to an increase of both input and output parts of the water balance.

Keywords: climate change, water balance, period of climatic norm, long-term period, Western Bug River basin
