Geophysical mass flows—debris flows, avalanches, landslides—can contain O(106–1010) m3 or more of material, often a mixture of soil and rocks with a significant quantity of interstitial fluid. These flows can be tens of meters in depth and hundreds of meters in length. The range of scales and the rheology of this mixture presents significant modelling and computational challenges. This paper describes a depth-averaged ‘thin layer’ model of geophysical mass flows containing a mixture of solid…

TITAN2F: a pseudo-3-D model of 2-phase debris flows
Abstract. Debris flows, avalanches, landslides, and other geophysical mass flows can contain O(106–1010) m3 or more of material. These flows commonly consist of mixture of soil and rocks with a
A Model for Granular Flows over an Erodible Surface
This paper describes an approach to incorporate the interaction between a mass flow, an erodible bed, and the topography of that bed, using the kinetic theory for rapid granular flow to model a “mixing” layer.
Numerical Modeling of Two-Phase Gravitational Granular Flows with Bottom Topography
We study a depth-averaged model of gravity-driven mixtures of solid grains and fluid moving over variable basal surface. The particular application we are interested in is the numerical description
A mathematical framework for modelling rock–ice avalanches
Abstract Rock–ice avalanches are liquid–granular flows that consist of a mixture of rock, ice and a liquid. The dynamics that distinguishes these types of flows from other geophysical flows is the
Modelling and numerical simulation of two-phase debris flows
Gravity-driven geophysical mass flows often consist of fluid–sediment mixtures. The contemporary presence of a fluid and a granular phase determines a complicated fluid-like and solid-like behaviour.
A two-phase shallow debris flow model with energy balance
This paper proposes a thin layer depth-averaged two-phase model provided by a dissipative energy balance to describe avalanches of solid-fluid mixtures. This model is derived from a 3D two-phase
A two-phase model for dry density-varying granular flows over general topography
Landslides, debris flows or granular avalanches are comprised of mixtures of grain-particles (sand, gravel and rocks) and an interstitial fluid (water or air). This work is concerned with an
A model for geotechnical analysis of flow slides and debris flows
Flow slides and debris flows incorporate a broad range of sediment-fluid mixtures that are intermediate between dry rock avalanches and hyperconcentrated flows. Following a comprehensive review of
Investigations of Gravity-Driven Two-Phase Debris Flows
A depth-integrated theory is derived for the gravity-driven two-phase debris flows over complex shallow topography. The mixture theory is adopted to describe the mass and momentum conservation of
A two-phase model for numerical simulation of debris flows
Abstract. Debris flows are multiphase, gravity-driven flows consisting of randomly dispersed interacting phases. The interaction between the solid phase and liquid phase plays a significant role on


Flow of variably fluidized granular masses across three‐dimensional terrain: 1. Coulomb mixture theory
Rock avalanches, debris flows, and related phenomena consist of grain-fluid mixtures that move across three-dimensional terrain. In all these phenomena the same basic forces govern motion, but
A constitutive theory of fluid-saturated granular materials and its application in gravitational flows
Abstract A continuum theory of fluid-saturated granular materials is presented. The microstructural effects are accounted for by additional balances of equilibrated forces. A set of constitutive
The physics of debris flows
Recent advances in theory and experimentation motivate a thorough reassessment of the physics of debris flows. Analyses of flows of dry, granular solids and solid‐fluid mixtures provide a foundation
The motion of a finite mass of granular material down a rough incline
Rock, snow and ice masses are often dislodged on steep slopes of mountainous regions. The masses, which typically are in the form of innumerable discrete blocks or granules, initially accelerate down

Two-dimensional spreading of a granular avalanche down an inclined plane Part I. theory
SummaryThis paper is concerned with the motion of an unconfined finite mass of a granular material released from rest on an inclined plane. The granular mass is treated as a frictional Coulomb-like
The Savage–Hutter avalanche model: how far can it be pushed?
The conclusion of the analysis is that the SH model is a valid model for sand avalanches, but its Mohr–Coulomb sliding law may have to be complemented for snow avalanches by a second velocity-dependent contribution.
