Diffusion in the presence of high-diffusivity paths is an important issue of current technology. In metals high-diffusivity paths are identified with dislocations, grain boundaries, free surfaces and internal microcracks. In porous media such as rocks, fissures provide a system of high-flow paths. R

We consider the problem of diffusion in regions containing a finite number of continuously distributed families of high-diffusivity paths. We assume linear diffusion processes and WC provide differential expressions for the partial and total concentrations, The basic equations arc specialized to stu
