RDAVT RDAVT
RDAVT.r is an R Shiny-based app used to estimate immobile porosity, mobile porosity, and the mass transfer rate coefficient in dual-domain porosity media. The app allows for interactive fitting of the fluid versus bulk conductivity hysteresis curve from electrical tracer experiments using a semi-analytic graphical approach.
Per- and Polyfluoroalkyl Substances (PFAS) in U.S. Tapwater: Comparison of Public-Supply and Underserved Private-Well Exposures and Associated Health Implications Per- and Polyfluoroalkyl Substances (PFAS) in U.S. Tapwater: Comparison of Public-Supply and Underserved Private-Well Exposures and Associated Health Implications
This software involves files to fit the statistical models described in Smalling et al. Specifically, there are R scripts and associated stan model files (when appropriate) for comparing PFAS concentrations among public-supply and private-wells and as a function of geospatial predictor variables. There is also an R script for modeling the number of PFAS chemicals detected among water...
Heavy Heavy
Heavy is a Fortran program for calculating the change in gravity caused by the change in groundwater storage as predicted by a MODFLOW groundwater-flow model. Gravity change is calculated relative to the initial time step at user-specified locations (e.g., measurement locations). At each location, the gravitational attraction is the sum of the attraction caused by storage change...
Golden Eagle Survival in the Great Plains, Nestlings, with Territory and Time Random Effects - Supplemental Code Golden Eagle Survival in the Great Plains, Nestlings, with Territory and Time Random Effects - Supplemental Code
R code for modeling survival of nestling and fledgling golden eagles. It is supplemental material for a manuscript submitted to Journal of Raptor Research.
precompute precompute
The R package precompute is used to perform periodic computations to set up data for loading and rendering in Shiny applications. These computations typically take too long to conduct on the fly, which is why they are performed with some frequency using this package.
