In crystalline rocks, fracture networks control fluid flow (i.e. rock permeability). Inhomogeneous distribution of fracture aperture width due to natural fracture topology may produce inhomogeneous fluid flow (channel flow). Hydrothermal experiments for a tensile fracture in granite indicate that the effect of aperture width distribution and any inhomogeneity is pronounced. Numerical simulation for 2-D fluid flow through a facture shows that inhomogeneity of fluid flow may be enhanced, and promote fluid channels within the rock.
