Abstract
Among many types of natural hazards normally available, this work treats of a particular one called debris flow. One of the salient aspects of debris flow occurrence is linked to the reciprocal interaction of the solid and fluid components. Starting out from this consideration, this study develops a modelling methodology, based on dimensional analysis and on a quadratic type approach, which takes into consideration the entire field of visco-plastic and collisional-turbulent interactions. The good correlation between data calculated with the model and data measured in real events in the field, underlines the strength of the rheological model proposed, sufficiently close to the physics of the processes and representative of experimental evidence. 1 Introduction Phenomenolo
