The following parameters can be edited on this tab:

 

Name: This is the name of the collection system.

 

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

 

Number of Sublayers: This is the number of sublayers to use for the collection system. Typically, a value of 1 is used.

 

Thickness: This is the thickness of the collection system.

 

Density: This is the density of the collection system.

 

Diffusion Coefficient: This is the coefficient of hydrodynamic dispersion for the collection system.

 

Distribution Coefficient: This is the distribution coefficient for the collection system.

 

Porosity: This is the porosity of the collection system.

 

Phase Parameter: This is a dimensionless phase parameter, ‘KH’ or ‘Sgf’, as discussed in the Introduction. The default is one; this represents no phase change.
