Early-stage interaction between settlement and temperature-gradient metamorphism

Journal of Glaciology, 2017
Snow metamorphism and settlement change the microstructure of a snowpack simultaneously. Past experiments investigated snow deformation under isothermal conditions. In nature, temperature gradient metamorphism and settlement often occur together.

Influence of slab depth spatial variability on skier-triggering probability and avalanche size

Annals of Glaciology
Spatial variability of snowpack properties adds uncertainty in the evaluation of avalanche hazard. We propose a combined mechanical–statistical approach to study how spatial variation of slab depth affects the skier-triggering probability and possible ...

Dynamic models for impact-initiated stress waves through snow columns

Journal of Glaciology
The 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 Sciences
Understanding 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 ...

Stress measurements in the weak layer during snow stability tests

Annals of Glaciology
The 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.
