Dynamic models for impact-initiated stress waves through snow columns
Journal of GlaciologyThe objective of this research is to model snow's response to dynamic, impact loading. Two constitutive relationships are considered: elastic and Maxwell-viscoelastic.

The effect of slab touchdown on anticrack arrest in propagation saw tests [PDF]
Natural Hazards and Earth System SciencesUnderstanding crack phenomena in the snowpack and their role in avalanche formation is imperative for hazard prediction and mitigation. Many studies have explored how structural properties of snow contribute to the initial instability of the snowpack ...

SNOWMIP2: An evaluation of forest snow process simulation [PDF]
, 2009 The Northern Hemisphere has large areas that are forested and seasonally snow covered. Compared with open areas, forest canopies strongly influence interactions between the atmosphere and snow on the ground by sheltering the snow from wind and solar ...

Stress measurements in the weak layer during snow stability tests
Annals of GlaciologyThe snow compression test is a snow stability test where an isolated column of snow is progressively loaded by tapping on it to induce failure in a possible weak layer.

Micrometeorological processes driving snow ablation in an Alpine catchment [PDF]
, 2011 Mountain snow covers typically become patchy over the course of a melting season. The snow pattern during melt is mainly governed by the end of winter snow depth distribution and the local energy balance.

Viscoelastic analysis of stress waves through cohesive snow in layered and 2D configurations
Journal of GlaciologyDynamic surface loads generate stress waves in snow that can trigger slab avalanches. Previously, we determined Maxwell-viscoelastic model parameters from one-dimensional, homogeneous laboratory experiments resembling Compression Tests (CTs).

Microstructure-based modeling of snow mechanics: a discrete element approach [PDF]
The Cryosphere, 2015 Rapid and large deformations of snow are mainly controlled by grain rearrangements, which occur through the failure of cohesive bonds and the creation of new contacts. We exploit a granular description of snow to develop a discrete element model based on
