Philip's equation infiltration example
Webb1 nov. 1990 · A general infiltration model is derived using a systems approach. The models of Horton, Kostiakov, Overton, Green and Ampt, and Philip are some of the example models that are shown as special cases of the general model. An equivalence between the Green‐Ampt model and the Philip two‐term model is shown. The general model also … Webb4 okt. 2024 · The infiltration rate can be calculated via Equation ( 12 ): (12) where i is the infiltration rate, cm/min; S is the moisture absorption rate, cm/min, indicating the capacity of soil water absorption caused by the matrix potential difference; and A is the steady infiltration rate, cm/min.
