Advanced Groundwater Vistas
Advanced Groundwater Vistas is the first Windows modeling environment for the MODFLOW family of models that allows for the quantification of uncertainty. The approach used by Stochastic MODFLOW is the Monte Carlo technique, a common method employed by groundwater professionals for assessing risk. In the past, however, these risk assessments have relied primarily on simple analytical solutions and calculations. Here for the first time is a practical tool for assessing risk using more complex and real-world groundwater models.

MODFLOWwin32
MODFLOWwin32 is a advanced pre and postprocessing version of this popular groundwater flow model, originally developed by the USGS. MODFLOW is a 3D finite-difference groundwater flow model, and there are many versions available. Unlike other versions of MODFLOW, however, MODFLOWwin32 was developed specifically for Microsoft Windows (Win32s) and Windows NT. Using a unique technology, MODFLOWwin32 runs as a DLL which is controlled by a shell program or by ContourWin32 which is provided with MODFLOWwin32.
- Runs 10 to 20 percent faster than other versions of MODFLOW for DOS!
- Contains the BCF2, BCF3, PCG2, STREAM Routing, and Aquifer Compaction Packages
- User interface organizes file names and allows user to abort the simulation or force convergence when the solution oscillates
- Uses all memory available to Windows, including virtual memory
- Reads files created by all popular MODFLOW preprocessors
- All MODFLOW manuals have been reformatted as Windows Help files
- Provides several user-selectable levels of multi-tasking, even under Windows V3.1
- Iteration data displayed as MODFLOWwin32 runs.
Advanced Groundwater Vistas
Stochastic MODFLOW and Groundwater Vistas is the first modeling environment for the MODFLOW family of models that allows for the quantification of uncertainty.
Stochastic MODFLOW includes
- Monte Carlo versions of MODFLOW, MODPATH and MT3D
- New stochastic processing features in Groundwater Vistas
- Groundwater Vistas User's Guide and Documentation
- Tutorial for beginners
- Geostatistical Simulators
The approach used by Stochastic MODFLOW is the Monte Carlo technique, a common method employed by groundwater professionals for assessing risk. In the past, however, these risk assessments have relied primarily on simple analytical solutions and calculations. Here for the first time is a practical tool for assessing risk using more complex and real-world groundwater models. We are excited about these new Monte Carlo models and hope that Stochastic MODFLOW will bring groundwater modeling to a new level.
Types of Graphical Displays for Advanced Groundwater Vistas

Why Groundwater Vistas
- Windows!
The other major groundwater modeling products were ported from Unix or DOS. GV was designed for Windows 95, 98, 2000, and XP exclusively. GV offers cut/copy/paste, WYSIWYG printing, and a multi-document interface.
- Telescopic
Mesh Refinement
Telescopic Mesh Refinement (TMR) is the process of creating a local scale Refined model from a large scale model. Both steady state and transient TMR models can be created. No other modeling interface has this capability!
- Automated
Calibration
GV already supports not just one but a variety of inverse (auto-calibration) models including PEST, UCODE, and a new inverse model built right into the GV interface. You may calibrate on any combination of aquifer parameters including hydraulic conductivity, vertical conductance, boundary head, well flow rate, recharge, and evapotranspiration. No other modeling interface has this capability!
- All
MODFLOW Versions
GV supports all versions of MODFLOW, MT3D, and MODPATH, including MODFLOW'96, MODFLOWT, MODFLOW-SURFACT, MT3D'96, MT3DMS, and RT3D. No other modeling interface has this capability!
- RT3D
Model
GV supports the use of the RT3D model, a multi-species reactive transport code based on MT3D. RT3D is designed to simulate natural attenuation processes, accelerated bioremediation schemes, and dissolution of NAPLs.
- Monte
Carlo Risk Analysis
You may upgrade the standard GV to Stochastic Groundwater Vistas and get special Monte Carlo versions of MODFLOW, MODPATH, and MT3D. No other modeling interface has this capability!
- 3D
Visualization
GV exports data to a variety of formats for viewing model results using the latest 3D products, including Slicer, Earth Vision, EVS, Environmental Workbench, Tecplot, and others. No other modeling interface supports this many formats!
- Hydrostratigraphic
Units
GV now includes the option of defining hydrostratigraphic units, which are defined by grouping aquifer units together. Several zones, spanning several layers can be grouped together, for performing group sensitivity analyses and calibration. This new feature saves you time!
- Matrix
Calculator
This important new feature allows you to display a combination of any selected model parameters (conductivity, recharge, layer elevation, etc.) or computed value (head, concentration, velocity, etc.) This enables you to show input/output relationships.
- Import/Export
Anything!
You may import just about any type of data into Groundwater Vistas and export it back out again. File types include SURFER grid files, DXF files, ASCII text files, matrix files, MODFLOW files, etc. You may also use cut/copy/paste to and from any spreadsheet in GV.
System Requirements For Groundwater Vistas
