We propose a new model for transport in disordered solids and rocks which contain N distinct families of transport paths (N≥2), and study the behavior of its effective transport properties. The model is relevant to transport in metals, polycrystals, porous catalysts, coalbed methane reservoirs, and geological systems with fractures and pores.
