Summary
A modified version of the three-dimensional, variable-density solute-transport model (SUTRA) was developed to simulate the effects of erosion and uplift on the flushing of brine with meteoric water in Permian through Mississippian rocks of the Appalachian Plateaus. The model was run in 10-Ma transient simulations for a range of values of permeability and anisotropy. Model results indicate that the depth of shallow Paleozoic brine in the Appalachian Plateaus is controlled by the flushing rate of brine and the uplift/erosion rate. Knowledge concerning the erosion rate and the depth of brine can allow estimation of the effective regional permeability of the sedimentary rock. This USGS data release contains all of the input and output [...]

Model results indicate that the depth of shallow Paleozoic brine in the Appalachian Plateaus is controlled by the flushing rate of brine and the uplift/erosion rate. Knowledge concerning the erosion rate and the depth of brine can allow estimation of the effective regional permeability of the sedimentary rock. This USGS data release contains all of the input and output files for the simulations described in the associated model documentation report (https://doi.org/10.1002/2017GL072980). This data release also includes (1) the modified SUTRA (v2.2) source code, and (2) ancillary files used to create the model mesh with Argus ONE, export model input files with MODELMUSE, and a summary of model results in EXCEL spreadsheets.
This groundwater model was created to explain the persistence of shallow Paleozoic brine in the Appalachian Plateaus and to determine the factors that control the depth of brine and the overlying freshwater thickness. The development of the model input and output files included in this data release are documented in https://doi.org/10.1002/2017GL072980.
