RESUMO

A hybrid method using the Laplace transform and the finite difference method has been considered to determine the wetting profile in a soil submitted to an infiltration process. This scheme has been applied to the case of a semi-infinite column of sand, satisfying the constant flux condition at the surface. The numerical results and the experimental water content profiles are in good agreement.
