The Primary and Secondary Liner Landfill model is used to quickly enter a landfill that may contain a primary leachate collection system, primary composite liner, secondary leachate collection system, secondary composite liner, aquitard, and aquifer. In this option the composite liners can be composed of a geomembrane and/or compacted clay or GCL.

 

If the model was created using the Primary and Secondary Landfill 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.
