Abstract
A new area of complex research has been announced, which is dedicated to the study of the influence of elastic waves of cover sediments and electric fields of the atmosphere and lithosphere on the movement of liquid and gaseous phases in the geological environment. In this work, the data of measurements of electric fields and the responses of hydrogeological indicators in the cover sediments to them were used for scientific analysis. Often, the effect of electric fields comes into conflict and even dominates the factors that are traditionally perceived as the main ones in the formation of the groundwater regime (precipitation, humidity gradients). The positive charge of the static electric field of the surface atmosphere contributes to the transfer of bound and condensed moisture to groundwater in dry periods. In the conditions of changing the infiltration regime of groundwater to infiltration-evaporation, the role of vaporous moisture condensation in the recharge of groundwater increases, which is one of the main signs of the influence of global temperature increase on water exchange processes. The groundwater level fluctuations occur even without the inflow or loss of moisture from the horizon, which must be taken into account during balance calculations using hydrodynamic numerical methods.
