The principal features of debris flow are described. One section is devoted to debris-flow triggering, accounting for the geomechanical criteria by Takahashi (1978) and for most recent hydrological distributed models. In a second section, the rheology of debris flows is described: the theory of dispersive stresses by Bagnold, the kinetic theories of dense gases, and some recent experimental observations about debris flows in equilibrium. A section is devoted to mathematical models and the final section discusses debris flows countermeasures.
