title: Percolation and permeability of networks of heterogeneous fractures.
abstract: Networks composed by heterogeneous fractures whose local permeability is a binary correlated random field are generated. The percolation and permeability properties of a single heterogeneous fracture are strongly influenced by finite size effects when the correlation length is of the order of the fracture size. For fracture networks, a mean-field approximation is derived which approximates well the macroscopic permeability while an empirical formula is proposed for the percolation properties.
