Overview | ShowFlow 2 | HSSM-WIN | ShowFlow 4 | ShowFlow X

The ShowFlow Modeling Interface is a graphical user interface for groundwater models. It is designed as a front end for existing DOS-based models, and runs as a Multiple Document Interface (MDI) program under every version of Microsoft Windows since 3.1x.

ShowFlow provides dialog boxes for model input data entry, and constructs an input file according to the DOS model's requirements. Model output files are read for data which are displayed as graphs in MDI document windows. Several graphs from different model simulations can be compared on the screen simultaneously, and graphs may be exported to the Windows clipboard for inclusion in other programs, such as word processors or graphics programs.

ShowFlow has to date been applied to two groundwater contaminant transport programs (SSGPlume and HSSM), with more in the works!

Best of all, since ShowFlow was first developed by a student supported by the taxpayers of the State of Texas and of the United States, it is free! And so is the source code! All I ask is that if you use ShowFlow, let me know.

ShowFlow 2
This implmentation of ShowFlow is for a steady state gaussian plume groundwater contaminant transport model, SSGPlume, developed by Virgina Smith, Randy Charbeneau, and John Tauxe at the Center for Research in Water Resources of the University of Texas at Austin. ShowFlow 2 is written for the Windows 3.x environment, but has been successfully tested under all versions of Windows.

HSSM-WIN
The ShowFlow Modeling Interface has been adopted by the U.S. Environmental Protection Agency's Robert S. Kerr Environmental Research Laboratory to drive its Hydrocarbon Spill Screening Model. The ShowFlow Interface, named HSSM-WIN, handles a complex input dataset and produces several different graphs of output data from the HSSM models.

Get HSSM-WIN from EPA, with the documentation, too.

And now it has been transplated into Spanish: ¡HSSM-WIN en Español!
ShowFlow 4 (still under wraps)
This will be called GRI-ShowFlow, and will be an enhanced version of ShowFlow 2.02 with added models for different source geometries and characteristics. GRI-ShowFlow is being developed and significantly improved by the Energy and Environmental Research Center of the University of North Dakota, under contract with the Gas Research Institute (now the Gas Technology Institute) and the U.S. Department of Energy.
ShowFlow X
This could be your model with a ShowFlow Interface specifically designed to run it. The design is general and flexible enough to accommodate many model data configurations and need not run an external DOS code, since a model could easily be incorporated into the C code for the ShowFlow executable.
