Abstract
This publication presents results of investigation of the hydrogeological and geotechnical conditions within natural boundary Mezhyhirya which located on the right bank of the Kyiv hydroelectric reservoir on the Dnieper River. The power sources of the aquifers were identified. It was established that the shaping of the groundwater levels regime was carried out by the rainfall infiltration in the aquifer directly on the site, the infiltration of precipitation in the adjacent areas and further transit on the territory, the transit from the reservoir of the Kiev pumped-storage. It was proved that in the annual cycle the levels regime and the variability of rainfall have a close correlation with the time lags of levels in the magnitude of 1.2 to 4 months. Dependencies of the levels time lags in relation to precipitations were found. The dependencies are shown in the reduction of time lags approaching to the groundwater discharge zone and in a direct correlation between the lags and altitudes of the levels in the same direction and, therefore, in an inverse correlation with the power of the aeration zone.
