Abstract: The kinematic overland flow and the Green-Ampt infiltration equations are coupled and rewritten in terms of several nondimensional parameters. Constant values of these parameters imply hydraulic similarity of an infinite number of different overland flow-infiltration situations. Therefore, the results obtained in terms of these nondimensional parameters can be generalized. A four-point implicit finite difference scheme is employed to solve the governing equations, and the results are presented in chart form.
