Large avalanches usually encounter different snow conditions along their track. When they release as slab avalanches comprising cold snow, they can subsequently develop into powder snow avalanches entraining snow as they move down the mountain. Typic...

The intermittency regions of powder snow avalanches (2018)
Journal Article

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...

From episodic avalanching to continuous flow in a granular drum (2018)
Journal Article
Balmforth, N., & McElwaine, J. (2018). From episodic avalanching to continuous flow in a granular drum. Granular Matter, 20(3), Article 52. https://doi.org/10.1007/s10035-018-0822-1

Experiments are conducted to study the transition from episodic avalanching (slumping) to continuous flow (rolling) in drums half full of granular material. The width and radius of the drum is varied and different granular materials are used, ranging... Read More about From episodic avalanching to continuous flow in a granular drum.

GEODAR Data and the Flow Regimes of Snow Avalanches (2018)
Journal Article
Köhler, A., McElwaine, J., & Sovilla, B. (2018). GEODAR Data and the Flow Regimes of Snow Avalanches. Journal of Geophysical Research, 123(6), 1272-1294. https://doi.org/10.1002/2017jf004375

GEODAR, a custom radar system, images avalanches over the entire slope with high spatial and temporal resolution at the experimental test‐site Vallée de la Sionne in Switzerland. Between winter seasons 2009/10 and 2014/15, data has been acquired from... Read More about GEODAR Data and the Flow Regimes of Snow Avalanches.
