Mechanics of Debris Flows

by S. B. Savage, McGill Univ, Montreal, Canada,

Document Type: Proceeding Paper

Part of: Hydraulic Engineering

Abstract: The paper deals with the mechanics aspects of the modelling of debris flows and will focus on steady, fully developed flows. After a brief review of the types of constitutive equations that have been devised to model these flows, such as the viscoplastic Bingham models, Bagnold dispersive stress models, and generalized viscoplastic models, we shall describe some granular flow kinetic theory models and 'granular dynamics' computer simulations.
