Specifically, new simple expressions are given for ... WebThe modified version of the Green and Ampt equation was applied to determine rainfall excess and to predict total runoff for three major storms recorded by the Agricultural Research Service from 1957 to 1959 on a watershed near Oxford, Mississippi. A comparison of the prediction and the measured total runoff appeared to be promising.

It assumes a homogeneous soil profile and a uniform distri-bution of initial soil water content. The model assumes that a wetting front is present in the soil profile, and that the front separates the profile into an upper saturated zone ... rich kids of texas
