The following parameters can be edited on this tab:

 

Name: This is the name of the clay liner.

 

Symbol: This is the symbol used to draw the clay liner. To change the symbol click on the Change Symbol button.

 

Number of Sublayers: This is the number of sublayers to use for the liner. Typically, a value of 10 is used.

 

Thickness: This is the thickness of the clay liner.

 

Density: This is the density of the clay liner.

 

Conductivity K: This is the equivalent hydraulic conductivity of the clay liner. If you are unsure what the value of this is, it is recommended to use a leakage rate landfill.

 

Diffusion Coefficient: This is the coefficient of hydrodynamic dispersion for the clay liner.

 

Distribution Coefficient: This is the distribution coefficient for the clay liner.

 

Porosity: This is the porosity of the clay liner.
