The Vertical Migration model is used to quickly enter a model for the vertical migration of a contaminant from a waste mass into an aquifer. The model may contain a primary composite liner, aquitard, and aquifer. In this option the primary composite liner can be composed of a geomembrane and a primary liner. If the geomembrane is present the leakage through the geomembrane is calculated using equations by Rowe et. al., 2004.

 

If the model was created using the Vertical Migration template, the model form will display the model data on the left and the model output on the right. The model data can be entered in the tabs for General data, Source & Hydraulic Heads, Collection System, Geomembranes, Clay Liners, Aquitard, Aquifer, and Special Features. In addition, there is a tab for the subsurface model.

 

 

The data entry for the General data, Source & Hydraulic Heads, Collection System, Geomembranes, Clay Liners, Aquitard, and Aquifer is described in the sections below. The data entry for the Special Features is the same for all the templates and is described in the Editing Special Features section. Based upon the model data a subsurface model is displayed on the Subsurface Model tab, this is the same for all templates and is described in the section Displaying the Subsurface Model. The control of the display of the model output is the same for all templates and is described in the section Displaying Model Output.
