Groundwater Vistas (GV) is a unique groundwater modeling environment for Microsoft Windows that couples a powerful model design system with comprehensive graphical analysis tools. GV, developed by the author of ModelCadTM, is a model-independent graphical design system for MODFLOW and related models. In addition, GV supports the use of the PEST model-independent calibration software. The combination of PEST (a trial version is included with GV) and GV's automatic sensitivity analysis make GV a powerful calibration tool.

GV displays the model design in both plan and cross-sectional views using a split window (both views are visible at the same time). Model results are presented using contours, shaded contours, velocity vectors, and detailed analysis of mass balance. MODPATH particle traces are also displayed in both plan and cross-sectional views. Another unique aspect of GV is its use of grid independent boundary conditions. Grid-independent boundaries do not change position as the grid is modified. This allows the modeler to make major changes to the mesh without wasting time repairing the location of boundaries.

The Standard Version includes:

• Groundwater Vistas User's Guide and Documentation
• Tutorial for beginners

The advanced version of Groundwater Vistas provides the ideal groundwater risk assessment tool.

The Advanced Version includes:

• Monte Carlo versions of MODFLOW, MODPATH & MT3D
• New stochastic processing features in Groundwater Vistas
• Groundwater Vistas User's Guide and Documentation
• GV3 supports SWIFT (large discount on SWIFT if bundled with GV3)
• 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 modelling to a new level.

Models supported by Groundwater Vistas are: MODFLOW88, MODFLOW96 Double Precision, MODFLOW 2000, MT3DMS, SEAWAT, RT3D, MODPATH, Brute Force, MODOFC, SOMOS, MGO, PEST-ASP, and UCODE.
