FEP Effects
Description of FEP Effects
Vertical displacement of host rock and other rocks (differential uplift and subsidence of individual blocks), changes in stress field. Creation of preferential pathway; gradient and hydraulic conductivity changes. Dilution capacity of aquifer changes. May result in formation of ductile shear bands that could provide preferential pathways.
