SAUCEDO, Heber; ZAVALA, Manuel  y  FUENTES, Carlos. Use of Saint-Venant and Green and Ampt Equations to Estimate Infiltration Parameters based on Measurements of the Water Front Advance in Border Irrigation. Tecnol. cienc. agua [online]. 2016, vol.7, n.1, pp.117-124. ISSN 2007-2422.

A method is presented to estimate infiltration parameters using the Saint-Venant equations to describe the flaw of water over soil and the Green and Ampt equations to represent flow of water in the soil. The Levenberg-Marquardt method was applied to estimate the hydrodynamic parameters, namely saturated hydraulic conductivity and pressure in the wet front. By obtaining the model in this manner, the hydrodynamic parameters can be adjusted based on tests of the advance of the water front in border irrigation and the texture of the soil.

Palabras llave : Saint-Venant equations; Green & Ampt equation; Levenberg-Marquardt method.
