a GCL has a hydraulic conductivity of 5.0 x 10^-9a GCL has a hydraulic conductivity of 5.0 x 10^-9 cm/sec when subjected to a confining pressure of 0.44 psi (3Kpa). If this GCL is used as a liner beneath a 55-ft high landfill with a waste unit weight of 45 lb/ft3, what will be the hydraulic conductivity of the GCL at the bottom of the landfill?
