kitagawa: Spectral response of water wells to harmonic strain and pressure
Provides tools to calculate the theoretical hydrodynamic response
of an aquifer undergoing harmonic straining or pressurization. There are
two classes of models here: (1) for sealed wells, based on the model of
Kitagawa et al (2011), and (2) for open wells, based on the models of
Cooper et al (1965), Hsieh et al (1987), Rojstaczer (1988), and Liu et al
(1989). These models treat strain (or aquifer head) as an input to the
physical system, and fluid-pressure (or water height) as the output. The
applicable frequency band of these models is characteristic of seismic
waves, atmospheric pressure fluctuations, and solid earth tides.
