modflow_converter

General Module Function
 

The modflow_converter module will import MODFLOW data from the following sources.  For each, it is important that the reference files be present and any files referenced in those files also be in the same folder.

• MODFLOW98 :

• • Requires: *.BAS, *.BCF files

• MODFLOW2000

• • Requires *.NAM,*.DIS, *.BAS6 files

• GMS 8.1

• • Requires *.GPR file

• Visual MODFLOW

• • Requires *.VMG file

• Groundwater Vistas

• • Requires same files as MODFLOW

It will create time based EVS field files (.eff or .efz when Compress Files option is toggled) for the selected Output Data.

The MODFLOW simulation should be run to completion before the conversion is attempted.  

For GMS and Visual MODFLOW the project files will contain links to files generated by the simulation.  

Certain data will require additional files to be present.  

For example head data will be created once the MODFLOW simulation is complete, usually generating a binary *.hed file.  

This file should be referenced in the NAM file and then can be included in the generated EVS Field Files.

Concentration data is created when the MT3D simulation is run to successful completion and should be referenced in the NAM file as well.

Module Control Panel

The control panel of modflow_converter is shown above.

• The Load MODFLOW File button will select the model file to be imported.

• The Compress Files toggle when selected will change the output from (*.eff) field file to the compressed (*.efz) field file.

• The MODFLOW2000 toggle is active if a *.nam is selected.  When selected the module expects the model file to be associated with the MODFLOW2000 format as opposed to MODFOW98.

• The Crop Extents toggle when selected will return only the portion of the model that lies within the X/Y min-max range.

• The Porosity values slider is set to 1 by default.  In this instance the value indicated (0.3 by default) in the "All Layers" field will be the default value for porosity on all layers.  The slider can alternately  be increased to the number of layers in the model and the default value for each layer can be set.

• Each type of data in the output can be toggled on or off in the Output Data frame.  NOTE: Concentration (MT3D data) will generate a separate set of time based EVS field files.

• When the Accept All Values button is selected the module will parse the selected MODFLOW based file.  It will create three folders in the project directory:

• 1. GENERAL;

  2. MODFLOW and

  3. If Concentration has been selected MT3D. 

The GENERAL folder will have two files which contain the coordinates of each node and the connectivity for the cells.  The MODFLOW folder will contain the time based field files that include the selected MODFLOW data (i.e. Head, CCF, etc.).  The MT3D folder will contain the time based files that include Concentration data.
