          abstract = {We investigate mathematical properties of the system of nonlinear partial dierential
equations that describe, under certain simplifying assumptions, evolutionary processes in watersaturated
granular materials. The unconsolidated solid matrix behaves as an ideal plastic material
before the activation takes place and then it starts to 
ow as a Newtonian or a generalized Newtonian

uid. The plastic yield stress is non-constant and depends on the dierence between the
given lithostatic pressure and the pressure of the 
uid in a pore space. We study unsteady threedimensional

ows in an impermeable container, subject to stick-slip boundary conditions. Under
realistic assumptions on the data, we establish long-time and large-data existence theory.},
