Abstract

An infiltration model is developed which considers air viscous forces. The Buckley-Leverett soil moisture profile is used at surface ponding and thereafter. A viscous correction factor, beta , and an effective gravity correction factor, zeta , were utilized to simplify the resistance and gravity components respectively. These parameters proved to be extremely difficult to evaluate and were very sensitive to values of moisture content upstream of the Buckley-Leverett wetting front.
