SUTRA model used to evaluate the role of uplift and erosion in the persistence of saline groundwater in the shallow subsurface
Description
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 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.
