MODFLOW preprocessor.

[undara12]

I may need to investigate a groundwater mounding problem with more
than a one dimensional, analytical model.

Could someone recommend a preprocessor for MODFLOW that is GIS
based? I am investigating MODFLOW analyst for use in ArcGIS but have
not been able to learn much yet.

What do you think of the free, non-GIS based Processing Modflow 5.3.0
preprocessor? The interface seems clunky to me.

I heard of Grass (http://grass.itc.it/download/index.php) if you use
Linux, but never used it.

There are a variety of preprocessors for MODFLOW. I have listed some
below.

ModelMuse http://water.usgs.gov/nrp/gwsoftware/ModelMuse/ModelMuse.html
Argus ONE http://www.argusint.com/index.html
Groundwater Modeling System (GMS) http://www.aquaveo.com/gms
Groundwater Vistas http://www.groundwatermodels.com/
Processing MODFLOW for Windows http://www.pmwin.net/pmwin5.htm
Visual MODFLOW http://www.flowpath.com/

I am the author of ModelMuse and the MODFLOW GUI (which is a plug-in for
Argus ONE) so I'm most familiar with those. Both have some GIS
functionality built-in and can import Shapefiles. ModelMuse is
completely free. The MODFLOW GUI
(http://water.usgs.gov/nrp/gwsoftware/mfgui4/modflow-gui.html) is free
but requires a license for Argus ONE to operate.

I know very little about the MODFLOW Analyst. Here's what I've found on
the web.

According to http://www.aquaveo.com/archydro "The MODFLOW Analyst will
be available at an introductory cost of $1500 US." and has now been
released. Aquaveo is the same company that makes GMS.

More information about The MODFLOW Analyst is available at the following
