Infiltration in soils with a saturated surface

Key Points Analytic description of infiltration in soils Comparison of constant flux and saturated surface infiltration Linking infiltration to soil/water properties An earlier infiltration equation relied on curve fitting of infiltration data for the determination of one of the parameters, which limits its usefulness in practice. This handicap is removed here, and the parameter is now evaluated by linking it directly to soil-water properties. The new predictions of infiltration using this evaluation are quite accurate. Positions and shapes of soil-water profiles are also examined in detail and found to be predicted analytically with great precision
