Popis: Objective In order to understand groundwater systems, it is useful to study the changing characteristics and mechanisms of hydrogeological parameters with time. Responses of groundwater level microfluctuations to natural periodic loadings, such as earth tides and barometric pressure, serve as low-cost and effective investigation technique to calculate aquifer hydrogeological parameters. Methods In this paper, we systematically reviewed theoretical methods of hydrogeological parameters estimation based on groundwater level response to earth tides, barometric pressure, and their combination. We presented earthquake-related and mining-related parameters change with time in well-aquifer system. The barometric pressure response method also applies to the assessment of aquifer vulnerability. Results We conclude that studying the microfluctuation of groundwater level may provide insight into the interaction among hydrogeological processes, tectonic activities, and artificial influences in the shallow crust at spatial and temporal scales. Conclusion This paper also proposes three scientific problems to be solved in the future: the application of skin and wellbore storage effects, the improvement of computation accuracy of hydrogeological parameters by combining multiple methods for determining basic geological parameters, and the investigation of other artificial influences such as groundwater overdraft and subsidence to regional aquifer systems.
