Abstract

The occurrence of preferential flow, by-passing soil peds, is predicted from the occurrence of rainfall intensities in excess of pedal sorption; depth of preferential tracer penetration is estimated from the displacement of this excess through a small operational volume of preferential flow, θf. θf-values estimated from column drainage experiments to lie between 0.01 and 0.03 cm3 cm-3 for rainfall intensities from 1 to 10 mm hr.-1, increasing to ∼ 0.1 cm3 cm-3 at saturation. Observed tracer penetration is compared with predicted tracer penetration and mean profile θf-values are calculated. The preferential flow calculations discussed provide a useful approximation for characterising field tracer behaviour.
