FEP Effects

Description of FEP Effects

Reduced thickness of sediments and rocks overlying host rock, leading to unloading, decompaction and deconsolidation of the host rock and may affect its density, porosity, hydraulic conductivity and porewater composition. Possible formation of tension joints in host rock if the overburden becomes very thin. Changes in stress conditions, possibly leading to plastic deformation of clay (see FEPs 36, 37 and 38).
