Ground Water Vistas: a graphical user interface for the MODFLOW family of ground water flow and transport models.

For many ground water modeling applications, the time and effort spent on preprocessing of input data and postprocessing of output results may far exceed that spent on other project activities. Since the early 1990s, several graphical user interfaces that greatly facilitate the preand postprocessing tasks have become available and have been continually improved. Ground Water Vistas (GWV) is one such graphical user interface that supports several commonly used ground water flow and solute transport modeling programs, as well as related programs for sensitivity analysis, parameter estimation, and management optimization. GWV is developed by Environmental Simulations International and is available on the Web site http://www.groundwatermodels.com.
