Summary

The U.S. Geological Survey (USGS), in cooperation with the U.S Fish and Wildlife Service, has investigated the hydrology of the Great Dismal Swamp (Swamp) National Wildlife Refuge (Refuge) in Virginia and North Carolina and developed a three-dimensional numerical model to simulate groundwater and surface-water hydrology. The model was developed with MODFLOW-NWT, a USGS numerical groundwater flow modeling program, in combination with the Surface-Water Routing Process, a software package that simulates dynamic surface-water flows, water-control-structure management, and groundwater/surface-water interactions. The steady-state model was calibrated to average spring conditions using automated parameter estimation software (PEST) to reduce [...]

Purpose

The model was created to examine the effects of water-control structure operations on the groundwater and surface-water flows and levels within the Great Dismal Swamp of Virginia and North Carolina. The development of the model input and output files included in this data release are documented in the associated Scientific Investigations Report 2018-5056 (https://doi.org/10.3133/sir20185056).
