Modeling Ground-Water Flow with MODFLOW and Related Programs

Groundwater availability in the Crouch Branch and McQueen Branch aquifers, Chesterfield County, South Carolina, 1900-2012

“…If these conditions are met, then the mathematical treatment of this type of flow is well understood and well developed. Many different computer codes exist to simulate flow that meets these conditions, but MODFLOW is one of the most commonly used (Leake, 1997). The ACP aquifers of Chesterfield County are composed of sand, silt, and clay and are considered ideal for the use of MODFLOW as a groundwater-flow simulation tool.…”

“…(3) Data input instructions and theory are well documented (Leake, 1997). (4) A wide variety of computer programs written by the USGS, other Federal agencies, and private companies are available to analyze field data and construct input datasets for MODFLOW (Leake, 1997). (5) A wide variety of programs are available to read output from MODFLOW and graphically present model results in ways that are easily understood.…”

“…(2) Each simulation feature of MODFLOW has been extensively tested. (3) Data input instructions and theory are well documented (Leake, 1997). (4) A wide variety of computer programs written by the USGS, other Federal agencies, and private companies are available to analyze field data and construct input datasets for MODFLOW (Leake, 1997).…”

“…(5) A wide variety of programs are available to read output from MODFLOW and graphically present model results in ways that are easily understood. (6) MODFLOW has been accepted in many court cases in the United States as a legitimate approach to analysis of groundwater systems (Leake, 1997).…”

Hydrogeology, model description, and flow analysis of the Mississippi River alluvial aquifer in northwestern Mississippi

“…MODFLOW is the most widely used model code in the world for simulating ground-water flow (Leake, 1997). The modular design of the computer code for individual flow packages facilitates the use and application of the model for a variety of real-world conditions.…”
