Snow redistribution in an intermediate-complexity snow hydrology modelling framework [PDF]
The CryosphereSnow hydrological regimes in mountainous catchments are strongly influenced by snowpack heterogeneity resulting from wind- and gravity-induced redistribution processes, requiring them to be modelled at hectometre and finer resolutions.

Angle of repose experiments with snow: role of grain shape and cohesion
Journal of Glaciology, 2020 Snow appears as a granular material in most engineering applications. We examined the role of grain shape and cohesion in angle of repose experiments, which are a common means for the characterization of granular materials. The role of shape was examined

Frontiers in Earth Science, 2022 Spatially distributed meteorological information at the slope scale is relevant for many processes in complex terrain, yet information at this sub-km spatial resolution is difficult to obtain.

Stochastic equation of fragmentation and branching processes related to avalanches [PDF]
, 2015 We give a stochastic model for the fragmentation phase of a snow avalanche. We construct a fragmentation-branching process related to the avalanches, on the set of all fragmentation sizes introduced by J. Bertoin.

Unravelling the evolution of the Frébouge polygenetic cone in Val Ferret (Mont Blanc Massif)
Boreas, EarlyView.Proglacial settings in the Alps are typically polygenetic, often characterized by a complex and discontinuous interplay between glacial, fluvial and gravitational processes. These processes yield high volumes of sediments, which usually exceed their transportation capacity.

Temporal evolution of crack propagation propensity in snow in relation to slab and weak layer properties [PDF]
The Cryosphere, 2016 If a weak snow layer below a cohesive slab is present in the snow cover, unstable snow conditions can prevail for days or even weeks. We monitored the temporal evolution of a weak layer of faceted crystals as well as the overlaying slab layers at the ...

Shaping future forests: how can ecophysiology support climate‐smart forest management?
New Phytologist, EarlyView.Summary Climate change, particularly the associated increase in extreme events and disturbances, threatens the numerous environmental, social, and economic benefits that forests provide, both locally and globally. Heat and drought pose significant risks to forest ecosystems; the anticipated future climate is expected to exacerbate this trend ...

, 2001 Snow avalanches occur in many areas of Canada, mostly in remote or uninhabited locations. The few that impact society cause significant damage. Snow avalanches have killed over 570 people in Canada since the mid-1800s. Traffic delays and damage to forests cost millions of dollars annually.

Configurational energy and the formation of mixed flowing/powder snow and ice avalanches
Annals of Glaciology, 2016 A long-standing problem in avalanche dynamics is to model the flow of a mixed flowing/powder avalanche. Here we use the thermodynamic concept of configurational energy to describe the blow-out of air from the avalanche core. Configurational energy is the

Avalanche Defence Strategies and Monitoring of Two Sites in Mountain Permafrost Terrain, Pontresina, Eastern Swiss Alps [PDF]
, 2018 Snow-supporting avalanche defence structures are increasingly being built at high altitudes in potential permafrost areas. Special construction methods and guidelines have been developed to ensure a minimal stability of the structures, which have a vital
