Environmental Simulations, Inc. (ESI) software

Our most sophisticated groundwater modeling software is Groundwater Vistas, which is a pre- and post-processor for MODFLOW models. We support more MODFLOW features than any of our competitors, and we respond to new developments from the USGS faster than our competitors. We also focus on new technology for model calibration, optimization, and uncertainty analysis.

Aquifer test analysis is an integral part of groundwater modeling, supplying critical hydraulic parameters to the model or other basic groundwater calculations. Aquiferwin32 is a sophisticated Windows program that supports the analysis of aquifer tests, slug tests, and step tests. Multiple observation wells can be analyzed individually or as a group. AquiferWin32 also evaluates test data using the derivative method and can be used to simulate aquifer tests.

Most groundwater models are three-dimensional, but Groundwater Vistas does not have any 3D viewing capabilities. GW3D is an add-on to Groundwater Vistas that allows you to view your model grid, properties, and results in three dimensions. For transient simulations, the results can be turned into a simple animation movie.

We have our first mobile app in Apple`s App Store.  It is called GWModel and is free.  (Search for "groundwater" in the App Store and you should find it). GWModel displays your model grid on a street map, satellite photo, or hybrid map on your iOS device. We are also working on an Android version that should be out soon.
