Abstract: We outline the development of a hydraulic theory for a debris flow in which collisions between particles dominate the transfer of momentum and energy in a region of intensely sheared particles at the base of the flow. In this case, the hydraulic theory is completed using an analysis of the steady shearing of colliding particles driven by the relative motion of parallel boundaries. The shear stress transmitted through the shear layer to the material above it is determined in terms of the local velocity of the base of the flow and the height of the material above it.
