GGSD Program Details for WinTran

WinTran

Category	Contaminant transport (2D FEM)
Publisher	Environmental Simulations, Inc.
Platform	Win95/98, WinNT
Status	Commercial
Description	WinTran couples the steady-state groundwater flow model from WinFlow with a Finite Element Groundwater Contaminant Transport Model. The model is constructed automatically by the software but displays numerical criteria (Peclet and Courant numbers) to allow the user to avoid numerical or mass balance problems. Contaminant mass may be injected or extracted using any of the analytic elements, including wells, ponds, and linesinks. In addition, constant concentration elements have been added. WinTran displays both head and concentration contours and concentration may be plotted versus time at selected monitoring locations. The transport model includes the effects of dispersion, linear sorption (retardation), and first-order decay. Simulates steady-state flow and transient transport in confined and unconfined aquifers; Displays mass balance error during simulation; Contours concentration at user-specified time steps during simulation; Velocities computed either analytically or using finite-element flow model; Maps may be printed using any Windows device driver; All other features are the same as WinFlow (except transient flow model). A free demonstration version is available.
