Analysis of debris flow surges using the theory of uniformly progressive flow

Authors(s) and Affiliation(s)



Coarse debris flows develop surges with distinct longitudinal sorting. Although highly unsteady, such flow often appears to attain a steady-state condition, moving over long distances with approximately constant velocity and maximum depth. A simple model is presented, using the theory of uniformly progressive flow and incorporating zoned longitudinal variation in rheology. It is shown that non-homogeneity can cause very significant magnification of the peak discharge, depending on the slope angle and on the length of the frontal boulder concentration
