title: Colloid-facilitated contaminant transport in fractal media.
abstract: We investigate colloid-facilitated contaminant advection in strongly heterogeneous geological medium with fractal properties. Transport regimes and asymptotic behavior at large distances are studied for different relationships between sorption parameters and characteristics of percolation medium. Crossover times between transport regimes are determined.
