WinTRAN

Μοντέλο Μεταφοράς Ρύπων για Windows


WinTRAN couples the steady-state ground-water flow model from WinFLOW with a contaminant transport model. The transport model has the feel of an analytic model but is actually an embedded finite-element simulator. The finite-element transport 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.
WinTRAN aids in risk assessment calculations by displaying the concentration over time at receptor or observation locations. You simply click to define an observation point and run the simulation. WinTRAN will display the breakthrough curves after the simulation is finished.

Features include:

WinTRAN is, by far, the easiest contaminant transport model to use, especially since it is a true Windows program. It is unique in that it provides you with a sophisticated finite-element transport model that works like an analytic model. All of the finite-element mesh design chores go on behind the scenes, freeing you to work on the conceptual model and to try different solutions to your problem. WinTRAN incorporates the steady-state flow model from WinFLOW and, therefore, looks very much like WinFLOW.

The primary differences between WinFLOW and WinTRAN are the following:
If you plan to do a lot of flow simulation work in addition to transport, we recommend purchasing both models and we have provided special pricing considerations to allow you to obtain both models cost-effectively.

Requirements
