ABSTRACT

The paper presents the results of precise monitoring of the regime of groundwater at the
territory of the Geophysical Observatory of IDG RAS "Mikhnevo". Variations of water
level in the isolated aquifer depend on regime controlling factors that have episodic and
stationary effects on the aquifer. Detecting and studying the reaction of groundwater to
stationary lunisolar tides are of special interest. The tidal effect in variations of
groundwater level can be considered as a probing signal for diagnostics of stress-strain
conditions of the geological medium.

Keywords: aquifer, long-period trend, tidal component of the level, amplitude factor
