Abstract:
Laboratory experiments on granular avalanching of dry sands and gravels reveal a consistent pattern of runout distance varying with fall height, fall slope, and volume of material for volumes ranging from 0.1 to 1000 L. Data from the South Ashburton rock avalanche deposit show that its runout behaviour differs only slightly from that of the laboratory avalanches, extending the range of this behaviour to granular avalanches with volumes of about 100 000 m3. By contrast, data from much larger rock avalanches (> 107 m3) depart significantly from the trends of the laboratory data; some factor n

Abstract. Snow avalanches break, uproot and overturn trees causing damage to forests. The extent of forest damage provides useful information on avalanche frequency and intensity. However, impact forces depend on avalanche flow regime. In this paper, we define avalanche loading cases representing four different avalanche flow regimes: powder, intermittent, dry and wet. In the powder regime, the blast of the cloud can produce large bending moments in the tree stem because of the impact area extending over the entire tree crown. We demonstrate that intermittent granular loadings are equivalent t

Abstract:
In this paper we present a two-dimensional depth-integrated theory for the gravity-driven free surface flow of a granular avalanche over a helicoidal topography which is an important extension of the original Savage & Hutter theory. In contrast to other previous extensions, this local coordinate system is based on a generating curve with curvature and torsion. Its derivation was necessary because real avalanches are often guided by rather strongly curved and twisted corries. The motion of the avalanche follows the helicoidal talweg. The theory that is based on the helicoidal metric and non

Abstract:
AbstractDry snow avalanches consist of two distinct layers. A dense-flow layer is superposed by a powder-snow layer, a cloud of relatively small ice particles suspended in air. The density of this suspension is one order of magnitude smaller than that of the dense flow. A simulation model for dry avalanches has been developed, based on separate sub-models for the two layers. The sub-models are coupled by an additional transition model, describing the exchange of mass and momentum between the layers.

Abstract:
Design of deflectors or barriers to slow or stop snow avalanche debris in the runout zone requires estimates of runup height. In this paper, experimental data on runup of dense, dry granular flows in a flume are presented. The data are then compared with two one-dimensional theoretical equations for runup estimation: (1) a formulation based on following the leading edge of the flow up the barrier and (2) the traditional method adapted from equations presented by A. Voellmy for describing the centre of mass of the avalanche. The results show that the leading-edge model more closely matches the

Abstract:
Shallow-flow integrated numerical models of landslide and avalanche motion have recently experienced rapid development. An important aspect of model development is verification, to show that models are correct and reasonably robust in their application of basic physical principles. Most existing models have been verified against controlled laboratory experiments using dry granular material. In this article, it is shown that spreading flows such as the “dam-break” problem in frictional material pose problems for shallow-flow analysis.

Abstract:
We study water-immersed granular avalanches in a long rectangular cell of small thickness. By video means, both the angle of the granular pile and the velocity profiles of the grains across the depth are recorded as a function of time. These measurements give access to the instantaneous granular flux. By inclining the pile at initial angles larger than the maximum angle of stability, avalanches are triggered and last for a long time, up to several hours for small grains, during which both the slope angle and the granular flux relax slowly. We show that the relaxation is quasi-steady so that th

Abstract:
Underwater avalanches are a major risk to offshore structures. The mechanisms involved in the initiation and propagation of underwater granular avalanches are complex. They depend mainly on the slope angle, density, and quantity of material destabilised. Characterising the risk induced by such catastrophic flows requires the development of reliable models. Most models of submarine landslides assume a single homogeneous phase representing the grain-fluid mixture that is governed by a non-Newtonian fluid behaviour.

Granular materials are processed in many industries including agricultural, pharmaceutical, mining, and oil-sand and several geophysical processes such as landslides and avalanches. There are few models capable of predicting the flow of granular materials and particularly their collapse.
