Snow avalanches have a substantial impact upon human activity in mountainous regions. In this article I employ a climatological framework to examine the mechanisms by which snow avalanches occur. This is followed by a discussion of the hydrologic and geomorphic aspects of avalanches, and an examination of the current state of research as regards ...

Snow avalanches are a major natural hazard in most snow-covered mountain areas of the world. They are rapid, gravity-driven mass movements and are considered a meteorologically induced hazard. Snow avalanches are one of the few hazards that can be forecast, and in situ measurements of instability are feasible. Advanced hazard-mitigation measures exist,

This work is a critical update of the most recent and innovative developments of the avalanche science. It aims at re-founding it on clear scientific bases, from field observations and experiments up to strong mathematical and physical analysis and modeling. It points out snow peculiarities, regarding both static mechanical properties and flow dynamics,

Fracture mechanics of snow avalanches
Physical Review E, 2001Dense snow avalanches are analyzed by modeling the snow slab as an elastic and brittle plate, attached by static friction to the underlying ground. The grade of heterogeneity in the local fracture (slip) thresholds, and the ratio of the average substrate slip threshold to the average slab fracture threshold, are the decisive parameters for avalanche ...

The Intermittency Regions of Powder Snow Avalanches [PDF]
Journal of Geophysical Research F: Earth Surface, 2018 Powder snow avalanches are typically composed of several regions characterized by different flow regimes. These include a turbulent suspension cloud of fine particles, a dense basal flow, and an intermittency frontal region, which is characterized by large fluctuations in impact pressure, air pressure, velocity, and density, but whose origin remains ...

ABSTRACT After a general introduction to snow avalanches and their consequences, type classification is discussed, and classification schemes based on morphology, genesis and magnitude are described briefly. The first technical section deals with deformation and displacement of snow slopes prior to avalanche release, with the failure process, and ...

Avalanche is a generic word that describes various phenomena. In the case of snow avalanches, this diversity is closely linked to the diversity of properties of materials present within the flow. This is why the study of an avalanche site must be performed by an expert with a good field knowledge.
