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 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... Tags: Aquia aquifer, Atlantic Coastal Plain, Beaufort aquifer, Beaufort confining unit, Black Creek aquifer, All tags...

PP1773_unit_alt_grid is a polygon shapefile of surface altitudes for 16 hydrogeologic units as described in report Professional Paper 1773. Surface altitudes were interpolated and discretized to the 2-mile by 2-mile rotated grid used to simulate groundwater flow in the Atlantic Coastal Plain of North and South Carolina. Altitudes are available for 17 surfaces, hydrogeologic unit layer 1 (top - land surface) through Layer 16 (top...

A natural consequence of groundwater withdrawals is the removal of water from subsurface storage, but the overall rates and magnitude of groundwater depletion in the United States are not well characterized. This study evaluates long-term cumulative depletion volumes in 40 separate aquifers or areas and one land use category in the United States, bringing together information from the literature and from new analyses.
