# kitagawa

Tools to calculate the theoretical spectral response 

of fluid-pressure in a water well

to harmonic strains (e.g., tides, long-period seismic waves).

## Models of spectral response

This code calculates the response at two types of wells: a sealed well and

an open well (exposed to atmosphere).

### Sealed Well

The theoretical model for a sealed well, where fluids are isolated from atmospheric pressure, 

responding to dilational strains from seismic waves is from 

[Kitagawa, et al. (2011)](https://doi.org/10.1029/2010JB007794 "Frequency characteristics of the response of water pressure in a closed well to volumetric strain in the high-frequency domain") which this package is named after.

### Open Well

The first theoretical model for a sealed well responding to seismic displacements is from 

[Cooper, et al. (1965)](https://doi.org/10.1029/JZ070i016p03915 "The response of well-aquifer systems to seismic waves").

This package also includes support for the models in

[Hsieh, et al. (1987)](https://doi.org/10.1029/WR023i010p01824 "Determination of aquifer transmissivity from Earth tide analysis").

[Rojstaczer (1988)](https://doi.org/10.1029/JB093iB11p13619 "Intermediate period response of water levels in wells to crustal strain: Sensitivity and noise level"), and

[Liu, et al. (1989)](https://doi.org/10.1029/JB094iB07p09453 "Seismically induced water level fluctuations in the Wali Well, Beijing, China"), which are based on various sources (i.e., tides, atmospheric pressure, and seismic waves).

[Wang, et al. (2018)](https://doi.org/10.1029/2018WR022793 "Tidal Response of Groundwater in a LeakyAquifer—Application to Oklahoma") modifies these solutions to include leakage.

## Getting Started

You can install the package via

[CRAN](https://cran.r-project.org/package=kitagawa)

from within the `R` environment:

    install.packages("kitagawa")

Load the package library and take a look at the vignettes:

    library(kitagawa)

    vignette(package='kitagawa')

    

### Installing the Development Version

Should you wish to install the development version

of this software, the [remotes][2] library

will be useful:

    library(remotes)

    remotes::install_github("abarbour/kitagawa")
