Groundwater Models

Groundwater models are used to simulate groundwater flow and assess groundwater availability.


Effective water planning and management requires an accurate assessment of the location and quantity of the State’s groundwater resources. The United States Geological Survey (USGS), in cooperation with SCDNR, the South Carolina Department of Health and Environmental Control (SCDHEC), and the United States Army Corps of Engineers, is developing a computer model to simulate groundwater flow in the Coastal Plain province of South Carolina.

The MODFLOW model is expected to be completed and available for use before the end of 2019.

The model can be used to:

  • Determine groundwater availability.
  • Evaluate the impact pumping has on groundwater and surface water resources and on other groundwater users.
  • Evaluate future withdrawal scenarios to help maximize groundwater use and minimize undesirable effects of pumping.
  • Support the development of State and regional water plans.
