THE THEORY OF EXISTENCE OF DEBRIS-FLOW MIXTURE AS A KEY COMPONENT IN COMPUTING DEBRIS-FLOW CHARACTERISTICS
Abstract
It was established that the dependence between density of debris-flow mixture and minimum'slope of the channel, such that the debris-flow mixture can move without stopping and disintegrating, is ambiguous. The theoretical and experimental researches made it possible to develop the basic model of debris-flow process which allows to compute the basic debris-flow characteristics (volume, discharge, density) all the way from the start to its stopping on the debris cone or in the mudflow-storages reservoir. Key component of this model is the theory of existence of debris-flow mixture by means of which the course of debris-flow process is determined (that is, if a debris flow moves it can be enriched by solid component or partially disintegrated).
