Abstract:Debris flow is generally composed of a wide range of solid particles and viscous pore fluid.It flows at a high
velocity down a slope channel.Interactions between solid and fluid phases affected by multiple parameters govern the
rheological properties of debris flows.A dimensional analysis for a systematic study of the governing parameters is pre-
sented.Multiple dimensionless numbers with clear physical meanings are critically reviewed.The applications of field
data to the studying of natural debris flows are demonstrated.Specific values of dimensionless numbers for classifying
flow regimes of large-scale natural debris flows are obtained.Compared with previous small-scale physical model tests,
this study shows that the contact friction between particles dominates in natural debris flows.In addition,the solid inertial
stress due to particle collisions and the pore-fluid viscous shearing stress play key roles in governing the dynamic proper-
ties of debris flows.The channel width as a confinement to the flows can affect the solids discharge per unit width signifi-
cantly.A dimensionless number related to pore-fluid pressure dissipation is also found that can satisfactorily distinguish
between surge flows and continuous flows in the field.
