If the Leakage Type specified on the Geomembrane tab is Giroud and Bonaparte., 1992 the Giroud Leakage tab will be displayed. The following parameters can be specified on this tab:
Contact: This is the type of contact between the geomembrane and the underlying material (either the clay liner or aquitard).
Hole Type: This is the type of holes in the geomembrane, either circles or long (rectangles).
Permeation: This is whether or not to consider permeation through the geomembrane.
Hole Frequency: This is the number of holes per hectare or acre. The default is 2.5 per hectare.
Hole Area: If the Hole Type is Circle then this parameter will be displayed. It is the average area of the holes in the geomembrane.
Hole Length: If the Hole Type is Long then this parameter will be displayed. It is the average length of the holes in the geomembrane.
Hole Width: If the Hole Type is Long then this parameter will be displayed. It is the average width of the holes in the geomembrane.
Calculate Leakage: This button can be used to calculate and display the leakage (Darcy velocity) through the geomembrane.
