Abstract:

MODFLOW is a 3D, cell-centered, finite difference, saturated flow model developed by the United States Geological Survey (McDonald & Harbaugh, 1988). MODFLOW can perform both steady state and transient analyses and has a wide variety of boundary conditions and input options.

MODFLOW is divided into a series of components called "packages." Each package performs a specific task. Some of the packages are always required for a simulation and some are optional. The input for each package is contained in a separate text file.
