GGSD Program Details for WinFlow

WinFlow

Category	Groundwater flow (2D)
Publisher	Environmental Simulations, Inc.
Platform	Win3x
Status	Commercial
Description	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 stream lines, particle traces, and water-level contours. WinFlow has the same basic capabilities as Geraghty & Miller's QuickFlow software, although many features are different or enhanced. Some of the key features include: Simulates effects of wells, linesinks, ponds, and recharge; Imports map files in DXF format, QuickFlow format, or ModelCad format; Simple data input. Calibration targets and calculation of calibration statistics; The steady-state module simulates ground-water flow in a horizontal plane using analytical functions developed by Strack(1989). The transient module uses equations developed by Theis (1935) and by Hantush and Jacob (1955) for confined and leaky aquifers, respectively. Produces report-quality graphics using any Windows device driver. Output may also be exported to a wide variety of file types, including SURFER, Geosoft, Spyglass, Windows Metafiles, and AutoCAD-compatible DXF files. A free demonstration version is available.
