NAME
modflow-gui - Preprocessor and postprocessor graphical-user
interfaces for preparing MODFLOW-96 and MOC3D input
data and viewing model output for use within Argus
Open Numerical Environments (Argus ONE)
ABSTRACT
MODFLOW-GUI is a graphical preprocessor and postprocessor for the
U.S. Geological Survey modular, three-dimensional, finite-
difference, ground-water flow model (MODFLOW-96) and solute-
transport model (MOC3D). MODFLOW-GUI is implemented as plug-in
extensions (PIEs) for use with Argus ONE version 4.1, revision t or
later. Although Argus ONE runs on a variety of computing platforms,
the MODFLOW-GUI PIEs are only available for systems running
Microsoft Windows 9x or NT.
Note: The Argus ONE interface only works with MODFLOW-96 and not
with earlier versions of MODFLOW.
MODFLOW-GUI supports the following packages: BAS5, BCF5,
WEL5, RIV5, DRN5, GHB5, RCH5, EVT5, SOR5, SIP5, PCG2, DE4, and
MOC3D.
The following capabilities are NOT yet supported: STR1, HFB1,
CHD1, IBS1, RES1, TLK1, GFD1, and MODPATH.
HISTORY
Version 2.0 98/07/14 - Addition of MOC3D solute-transport model;
several cosmetic changes.
Version 1.41 97/08/12 - Error corrected that occurred when
considering a confined aquifer and a transient simulation.
Version 1.4 1997/07/23 - Error corrected in export of storativity
for confined aquifers and in export of information for time-
variable and steady stresses. Specific data files can be
exported. Selected geospatial information is checked for errors
upon exporting.
Version 1.3 1997/06/02 - Error corrected in export of vertical
conductance. Problem corrected in postprocessing three-
dimensional surfaces.
Version 1.2 1997/05/13 - Error corrected in handling of "unconfined"
geologic units and in export of wetting threshold for
"unconfined" and "convertible" geologic units.
Version 1.1 1997/04/18 - Error corrected in handling of
"convertible" geologic units. Problem with real-value input
fields corrected. Units corrected in layer menu. Default values
in Misc. Controls and PCG Solver dialog boxes changed.
Version 1.0 1997/03/14 - Initial release.
DATA REQUIREMENTS
In order to use MODFLOW-96, initial conditions, hydraulic
properties, and stresses must be specified for every model cell in
the finite-difference grid.
OUTPUT OPTIONS
Output produced by the MODFLOW-GUI preprocessor is a complete set of
files for use with MODFLOW-96 and MOC3D.
SYSTEM REQUIREMENTS
MODFLOW-GUI is compiled for use with Argus ONE version 4.1, revision
t or later, on personal computers running Microsoft Windows 9x or
NT.
