It has been indicated that recharge is the same as during free infiltration for unsaturated infiltration and that a new system of boundary conditions has been proposed for saturated infiltration and redistribution of moisture. The volumes of infiltration calculated for those cases have also been compared with the results obtained in a simulation based on the conductivity equation, showing convergence.
