MODFLOW2000 and MODFLOW-ASP models used to simulate the groundwater flow in the Atlantic Coastal Plain, North and South Carolina and parts of Georgia and Virginia, Predevelopment to 2004

Description

A three-dimensional groundwater flow model (MODFLOW2000) of the Atlantic Coastal Plain aquifers
and confining units was developed to evaluate groundwater availability and to forecast the potential
effects of climate change on groundwater levels in the study area. Two existing groundwater flow
models that simulated flow and water use in the Coastal Plain aquifers of North Carolina (NC), South
Carolina (SC), and parts of Georgia and Virginia, were combined and updated to provide a single
model. Revisions to the model incorporated additional hydrogeologic, geologic, water-level, and
water-use data and hydrogeologic inconsistencies at the NC-SC border reconciled since the
development of the previous models. The new model simulates groundwater flow at regional and
intermediate special scales superimposed on a transient time scale from 1900 to 2004. This USGS
data release contains all of the input and output files for the simulation and calibration described in
the associated model documentation report (https://pubs.er.usgs.gov/publication/pp1773).
