摘要：We modelled the evolution of one dimensional kinematic wave on permeable saturated bed. The infiltration in the porous media is modelled through the equation of mass conservation in a differential volume of the ground, it was solved by a 20 finite element scheme. For the propagation of the kinematic wave in the open channel the infiltration is a source term and the correspondient equation was solved through the finite difference scheme of Lax - Friedrichs. The results were compared in both cases whith and whitout infiltration, and for different values of isotropic permeability.
