Crack propagation speeds in weak snowpack layers
Journal of Glaciology, 2022 For the release of a slab avalanche, crack propagation within a weak snowpack layer below a cohesive snow slab is required. As crack speed measurements can give insight into underlying processes, we analysed three crack propagation events that occurred ...

Recording microscale variations in snowpack layering using near-infrared photography [PDF]
, 2010 Deposition of snow from precipitation and wind events creates layering within seasonal snowpacks. The thickness and horizontal continuity of layers within seasonal snowpacks can be highly variable, due to snow blowing around topography and vegetation ...

Influence of stress, temperature and crystal morphology on isothermal densification and specific surface area decrease of new snow [PDF]
The Cryosphere, 2014 Laboratory-based, experimental data for the microstructural evolution of new snow are scarce, though applications would benefit from a quantitative characterization of the main influences.

On the saltation of fresh snow in a wind tunnel: profile characterization and single particle statistics [PDF]
, 2008 We present experimental results on the snow drift in a turbulent boundary layer over a flat fresh snow-covered surface. Vertical profiles of mass flux and of the distribution of particle diameters were obtained by means of a pair of Snow Particle ...

Automated snow avalanche release area delineation – validation of existing algorithms and proposition of a new object-based approach for large-scale hazard indication mapping [PDF]
Natural Hazards and Earth System Sciences, 2018 Snow avalanche hazard is threatening people and infrastructure in all alpine regions with seasonal or permanent snow cover around the globe. Coping with this hazard is a big challenge and during the past centuries, different strategies were developed.

Snow in a very steep rock face: accumulation and redistribution during and after a snowfall event
Frontiers in Earth Science, 2015 Terrestrial laser scanning was used to measure snow thickness changes (perpendicular to the surface) in a rock face. The aim was to investigate the accumulation and redistribution of snow in extremely steep terrain (>60°).
