After an analysis of the differences between stony inertial flows and viscous debris flows the emphasis is laid on the particle concentrations corresponding to different types of interaction between particles are defined. The sustaining mechanism might be the squeezing flow expelled from the void between approaching particles. The constitutive equations for viscous debris flows is given under an assumption on the origin of particle sustaining disperse pressure and shear stress. The characteristics of flow are deduced. If the material is a well graded mixture, the flow can transport a much larger solid concentration. A hierarchic buoyancy increment effect is suggested as a possible cause for the high competence to transport particles. / Aprè...
