In marcianito/hygra: Processing of HydroGravimetry data

HyGra: hydro-gravitational modeling with R

Description

This R-package is a collection of function which serve as a basis for hydro-gravitational projects. It evolved and grew throughout my PhD and hopefully helps others when dealing with this kind of data and projects. It provides a structure for the aspects of setups, calculations, pre- and post-processing, concerning hydro-gravitational projects:

• model domain preparation using DEMs (absolute UTM coordinates or relative coordinates)
• generating gravity component grids (circle, rectangular)
• remove effects of gravimeter pillar (circle, rectangular)
• determine conversion factor between gravity <> water (based on topography)
• forward modeling of gravity from water storage changes

Furthermore, this package consts the basis for further research projects which include coding in R, namely:

• Estimating and correcting gravity data for the umbrella effect
• Hydro-gravitational infiltration modeling
• Synthetic uncertainty analysis of standard gravity corrections

I am interested and open for further development and colaboration. For bug fixes, comments or further development please contact: [e-mail] or use github issues.

Installation

1. Start R

2. Install package via devtools: devtools::install_github("marcianito/HyGra")

3. load package: library(HyGra)

Dependencies

• r-base version 3.3.1
• following R-packages: devtools, dplyr, ggplot2, gstat, ptinpoly, raster, reshape2, viridis, zoo
