Infiltration models are often fitted to experimental data in soils, but few actually take ponded depth into account. In this study, the effect of ponded depth is considered by using a model which actually incorporates ponded depth. This is achieved by fitting the model to the experimental cumulative infiltration data and comparing the resultant sorptivity values with two other models where ponded depth is assumed to be zero. The results indicate that there is a 10 to 15% difference, depending on the crop treatment, in the sorptivity when ponded depth is taken into account. It is concluded that the model gives an excellent fit to the experimental data and provides a reliable way of obtaining the physical sorptivity with different ponded depths.
