摘要: The Green-Ampt model is generalized to infiltration into a multi-layered soil during an unsteady rain. One dimensional numerical simulation scheme of the Richards equation also developed which suitable deal with transfers between two kinds boundary conditions…water flux control and water head control. Modeling results are compared for cases 2 3 layered as examples. It shown that proposed matches quite well computation time less than tenth latter, thus promising play role in watershed modeling.
