A considerable amount of research indicates that the Green and Ampt infiltration equation can be used in hydrologic modeling with confidence. The parameters, however, still require considerable field and/or laboratory effort to determine estimated values. Reported here are alternatives for determining the average wetting front capillary pressure parameter. Only a moisture characteristic would be required.
