Three-region Campbell model for unsaturated hydraulic conductivity in undisturbed soils

A three-region Campbell type model for predicting undisturbed soil unsaturated hydraulic conductivity from water retention is presented. The model assumes that hydraulic conductivity follows separate Campbell functions within the macropore, the mesopore and the micropore regions, and that soil water...

Zusammenfassung:	A three-region Campbell type model for predicting undisturbed soil unsaturated hydraulic conductivity from water retention is presented. The model assumes that hydraulic conductivity follows separate Campbell functions within the macropore, the mesopore and the micropore regions, and that soil water retention and two reference-point values of hydraulic conductivity are known.
