抄録

A mechanism of occurrence of mud-debris flow due to the appearance of surface waterflow over a steep scree slope is discussed under the assumptions that the internal resistingstress distributes linearly and the excess pore pressure is negligible. The criterions for theoccurrence of non-stationary bed and partly stationary bed, which are the cases of mud-debrisflows, are theoretically and experimentally made clear.The mud-debris flows under the criterion of partly stationary bed approach the quasi.Steady flows, whose depths, velocities and concentrations are theoretically predictive applyingthe concept of dilatant fluid introduced by Bagnold. On the other hand, the depths or thefront heights of the mud-debris flows under the criterion of non-stationary bed monotonouslyincrease versus distance, but the velocities and concentrations are predictive by use ofsteady flow equations.Erosion processes of the scree slopes due to the passages of the mud-debris flows are alsodiscussed.
