Abstract
Abstract The numerical procedure of Hanks and Bowers was used to solve the moisture flow equation for boundary conditions corresponding approximately to those existing for infiltration into a field soil. Water diffusivity and retention data, necessary for theory calculations of infiltration, were measured on field cores by the outflow method. Infiltration estimates were obtained for a simulated two‐horizon soil with three nonuniform antecedent moisture profiles. Calculated infiltration rates were in good agreement with field rates measured with a sprinkling infiltrometer. Although not considered a substitute for field measurement, the numerical procedure appears to be a useful means of supplementing field measurement data by providing estimates of infiltration for simulated conditions of practical interest which are difficult to evaluate in the field.
