In closed-loop geothermal systems the underground may freeze and thaw due to intensive heat extraction. Phase change alters the sediments’ mechanical and hydraulic properties and their thermal behaviour, thus affecting the thermal plume propagation

In landfills, due to their low hydraulic conductivity, compacted clays (CC) are commonly used in multilayered structures as base liners and cover systems. Nevertheless, the hydraulic performances of the CC layer can be affected by temperature alterat
