Sale exit gradient, expressed by Khosla's theory of design of (a) the seepage gradient at the downstream exit point, equaling the effect of the submerged weight of a unit volume of soil there. (b) the actual seepage gradient available at the downstream exit point. (e) about 1/4 to 1/6 times the gradient which is just able to lift the soil grain at the downstream exit point.
