Analysis of Theoretical Concepts for Interpretation the Result of the Experimental Studies of Free Groundwater Level Oscillation in Wells

Abstract

A number of publications present the results of an experimental study
of free oscillations of groundwater piezometric level in wells with their
eigenfrequencies. The oscillations were initiated by a pulsed impact on
the aquifer through the well. Also in a number of publications a
theoretical interpretation was proposed for the established
phenomenon. However, the existing theoretical ideas about free
oscillations of the groundwater level seem to be incorrect. In the
present work, a critical analysis of these available theoretical concepts
is performed. The analysis served as an impetus to the development
of a consistent theory of relaxation filtration of groundwater.
