An attempt was made to model numerically the infiltration and redistribution of water in reclaimed topsoiled and non-topsoiled Appalachian minesoils. In these mine soils, large size fractions predominated. It was determined that infiltration and redistribution of applied water on topsoil spoil profiles could be adequately modelled with numerical techniques using either experimentally determined values or moisture characteristics corrected for coarse fragment content and hydraulic conductivities derived from seepage flux. On nontopsoiled profiles, numerical techniques appear inadequate. At times when the profile is reasonably dry, water seems to move rapidly through larger channels in the coarse spoil materials without appreciably wetting the rest of the profile.
