Five MODFLOW Ground-Water Modeling Utility Programs

These utilities are designed to extract and process information from input files prepared for, and output files generated by, MODFLOW, the U.S. Geological Survey’s three-dimensional ground-water flow model.

• GRID2GRIDFLOW reads a MODFLOW binary output file of cell-by-cell flow terms for one (source) model grid and converts the flow values to input flow values for a different (target) model grid.  The spatial and temporal discretization of the two models may differ.

Four raster-conversion utilities extract selected 2-dimensional data arrays in MODFLOW input and output files and write them to text files that can be imported into an ArcGIS geographic information system raster format:

• CBC2RASTER extracts selected stress-package flow data from a MODFLOW binary output file of cell-by-cell flows.
• DIS2RASTER extracts cell-elevation data from a MODFLOW Discretization file.
• MFBIN2RASTER extracts array data from a MODFLOW binary output file of head or drawdown.
• MULT2RASTER extracts array data from a MODFLOW Multiplier file.
