“…Most of the existing models are based on numerical approximations of the Richards equation, which has no general analytical solution. The techniques employed include the Finite Difference method (FDM) [11]; the Finite Element Method (FEM) [12,13]; and the Finite Volume Method (FVM) [14][15][16][17][18]. The use of the FDM and FEM is reported in the literature most frequently, because they offer computational advantages for solving parabolic-elliptic equations, such as the Richards equation.…”

“…Fully 3-D saturated-unsaturated flow and transport models Panday et al (1993) give the most appropriate simulation possibilities of these problems. However such model consume significant computation time to simulate large-scale flow and transport problems, which usually require meshes with large number of elements or grid blocks.…”

“…Las características de un suelo quedan definidas por factores tales como el grado de infiltración, la permeabilidad, la densidad aparente, la distribución de tamaños de los poros (Brusseau, 1991;Maciejewski, 1993;Panday et al, 1993;Gomis et al, 1995;Hoag et al, 1997), la agregación (Gavande, 1982;Häfele et al, 1999). La velocidad de infiltración del agua en un suelo depende de los factores anteriores, grado de saturación del suelo (Hillel et al, 1980), además de la temperatura del agua y del suelo (Rodriguez, 1982;Wierenga et al, 1982).…”
