           23 The
           24 .Nm
           25 utility outputs the maximum expected deformation depth in a sheared
           26 granular system with sinusoidal fluid-pressure perturbations from
           27 the top.
           28 It is assumed that the granular layer has uniform thickness and
           29 porosity.
