title: Directed random advection in a fractal medium.
abstract: The problem of tracer advection in random self-similar (fractal) media with strong anisotropy is solved. Transport regimes and concentration tails are described depending on the rate of velocity correlation function decay and on the degree of anisotropy. The influence of the finite correlation length of the fractal medium on transport regimes is analyzed. The derivation is conducted by means of scaling analysis.
