A Data Input Program (MFI) for the U.S. Geological Survey Modular Finite-Difference Ground-Water Flow Model
U.S. Geological Survey Water-Resources Investigations Report 94-468


MFI is a data input (entry) program for the U.S. Geological Survey modular three-dimensional finite-difference ground-water flow model commonly referred to as MODFLOW. Data for MODPATH, a particle tracking program for use with MODFLOW, can also be entered using MFI. MFI is designed to be easy to use and portable. It can also be used in conjunction with other programs so that the different parts of a model dataset can be entered using the most suitable program. Data are entered in MFI interactively through a series of display screens. MFI interfaces to a commercial spreadsheet program for entering two-dimensional arrays and lists of stress data. This report provides instructions for using MFI and information about making MFI run on different computers.
