Abstract

This study was conducted to determine whether increased pedogenic development of the Av (vesicular) horizon over relative time impacts the hydraulic properties of individual soil peds and the mechanism of infiltration as inferred by dye patterns. The AA. examined peds from the Av horizons associated with desert pavements that mantled 3 different alluvial deposits developed in the Mojave Desert (California) with different relative surface ages. The results suggest that infiltration through Av horizons evolves from a matrix-dominated process on the younger soils to a preferential flow-dominated process on older surfaces
