Моделирование грунтовой воды - теперь инструмент, обычно используемый в экологических проектах; однако, это берет квалифицированного аналитика, чтобы максимально использовать эту технологию.
Environmental Simulations, Inc. (ESI) was established to provide government and industry with superior groundwater modeling services, software, and training. Groundwater modeling is now a tool routinely employed in environmental projects; however, it takes a skilled analyst to make the most of this technology. A key issue today is the quantitative assessment of model uncertainty. ESI was the first to develop a Monte Carlo risk assessment tool for large-scale groundwater models (Stochastic MODFLOW). Another issue of concern is optimization of remedial strategies. ESI's Groundwater Vistas software was the first MODFLOW interface to employ mathematical optimization techniques and still supports more types of optimization technology than any other modeling program. A third issue that has always challenged modelers is accurately calibrating models. Again, ESI has been at the forefront of calibration technology through the implementation of the pilot point method with regularization and close ties to Dr. John Doherty, author of the popular PEST software.

Environmental Simulations, Inc. creates software for groundwater modeling and aquifer test analysis. Our software is windows-compliant and includes extensive documentation, plus the best technical support in the business-for free.

Groundwater Vistas
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.

Winflow is now part of AquiferWin32 and is an analytic two-dimensional groundwater flow and contaminant transport model. Wintran, the transport model, is now part of Winflow. Winflow models are easy to set up, and provide quick solutions to simple groundwater problems such as impacts from proposed water supply wells, small-scale groundwater contamination issues, or the design of small pump & treat systems. Winflow is included with the Modeling version of AquiferWin32.

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.
