MODFLOW-NWT model with SWI2 used to evaluate the water-table response to sea-level rise and change in recharge, Assateague Island, Maryland and Virginia
A three-dimensional groundwater flow model, MODFLOW-NWT with the SWI2 module, was developed
to provide a better understanding of the fresh groundwater system of Assateague Island, Maryland and
Virginia. Groundwater flow on Assateague Island was simulated to evaluate the effects of sea-level rise
and changes in recharge on the depth to freshwater below the land surface, changes in freshwater
discharge, and the depth of the freshwater/saltwater interface. The model was calibrated to average
2014-15 hydrologic conditions and vegetation. The model also simulated the movement of the freshwater-
seawater interface for three sea-level rise scenarios.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/10.3133/sir20205104).
