Since the problem geometry of the method is well defined, by means of a theoretical model, it is possible to calculate the permeability coefficient by means of equation 1, as described in Torrent and Frenzer, 1995.
Dado que en este método la geometría del problema está bien definida, mediante un modelo teórico es posible calcular el coeficiente de permeabilidad, tal como se describe en Torrent y Frenzer, 1995, aplicando la Ecuación 1.
