Groundwater Vistas (Student Version)
Introduction
	Groundwater Vistas (GV), developed by Environmental Simulations International (ESI), is a sophisticated Windows graphical user interface for 3-D groundwater flow & transport modeling using the MODFLOW suite of codes. We are grateful to ESI for making this student version of GV available to the readers of Applied Contaminant Transport Modeling for educational purposes.  The student version is fully functional except that it is restricted to the maximum model dimension of 50 columns, 50 rows and 5 layers.  For cross sectional models with only one row, the maximum number of layers allowed is increased to 50.  The student version is based on GV 3.18 (dated March 31, 2002) with support for MT3DMS 4.0 and the optimization model MGO.
