Based on a detailed analysis of the process of water infiltration into the soil, an alternative is proposed to adjust the input parameters of the Green-Ampt-Mein-Larson (GAML) model to optimize infiltration estimates of some Brazilian soils. The adjustments consisted of the replacement of the parameters saturated hydraulic conductivity (K0) by stable infiltration rate (Tie) and soil moisture saturation (qs) by water content in the transmission zone (qw). Moreover, an equation was established to estimate the matric potencial at the wetting […]
