Given the limitations previously listed, parameters Γ (permittivity) and Λ
(diffusivity) allow an easy comparison, referring to the steady-state conditions,
among double-layer barriers such as CCL plus an attenuation layer and GCL plus an
attenuation layer. The results of the comparison between these two types of liners
