Abstract
At the catchment of the Southern Bug River in the mode of level and consumption of groundwater to the river clearly distinguish phases, which are explained by the influence of temperature on the infiltration of winter and summer precipitations. From 1980 to 2014 there was an increase of the groundwater flow. The most stable growth trend - from 1980 to 1998. At the same time, the influence of temperature was lower, but its growth causes an increase of groundwater infiltration provision (mainly due to winter thaw). Since 1999, the weight factor of the temperature influence on the drainage has increased significantly, but there has been a decrease in the trend of the average annual consumption of underground drainage. During the last 20 years the amplitude between the annual minima and the maximum peaks of groundwater flow to the river has significantly increased, and a rapid drop of its volumes in 2015–2016 has been observed. If the trends of the groundwater reserves expenses over time will be deepened, this will be reflected in the resources of potable pressurized groundwater of the region.
