| Abstract: | In this paper, a simple infiltration model is proposed on the basis of a theoretical consideration of infiltration and the displacement of existing soil water by newly-infiltrating rainiail. A method for estimating the mean suction of the wetting front is given,and is applied to determine rainfall excess and to predict total runoff.Comparison of the predicted and the measured data shows excellent agreement. |
