Models of earth-tide-induced groundwater oscillations in the Police Basin, Czech Republic

Abstract

Earth-tide induced oscillations of hydraulic head occurring in a confined aquifer in an isolated block of rocks in the Police Basin, Czech Republic were studied. Two models were developed to demonstrate how earth-tide induced groundwater oscillations originate in the area. Due to the nature of the process, it was useful to utilize Biot's theory to predict the tidal oscillations. The resulting theory was applied in connection with two conceptual models involving geological structure of the site. This paper presents a sensitivity study of these models.
