Abstract

Taking into account rheological conditions of non-Newtonian liquids, the methods of quantitative assessment of dynamic indices of debris flow are considered to be in uniform motion in debris flow conduit. There are given stability criteria of initial uniform motion of debris flow and parameters of “monoclinal” growing wave at sharp increase of flow discharge during simultaneous evacuation of some debris sources with debris flow source.
