Modelling Version

Modelling version adds a full analytical modelling environment including Environmental Simulation's WinFlow analytical flow model (please click here for more details). WinFlow is an interactive, analytical model that simulates two-dimensional steady-state and transient ground-water flow (both confined and unconfined aquifers) with wells, uniform recharge, circular recharge/discharge areas, and line sources or sinks. The model depicts the flow field using streamlines, particle traces, and water-level contours.

WinFlow is simple to use and highly interactive, allowing you to create an analytical model in minutes. The software features standard Windows pull down menus and dialogs to facilitate the model design. Common menu selections and commands are also available on the toolbar. The entire WinFlow manual is available as on-line, context-sensitive help.
