A study on the size of snow particles in powder-snow avalanches [PDF]

Annals of Glaciology, 2001
AbstractIn this work, we study the size of the particles involved in a powder-snow avalanche. To determine this value, we study all the phenomena encountered by the particles before they arrive in the “body” of the avalanche. We study the boundary layer which is at the bottom of the avalanche. We determine, with the help of experimental data, the range

Avalanche dynamics by Newton. Reply to comments on avalanche flow models based on the concept of random kinetic energy

Journal of Glaciology, 2018
The critique by Issler and other (2017) of our avalanche dynamics model maintains that we disregard well-established results of particulate gravity flows.

Geospatial modeling of snow avalanches on the Šar Mountains, Balkan Peninsula [PDF]

Glasnik Srpskog Geografskog Društva
Snow avalanches are among the most significant natural hazards worldwide in high mountain areas. Mapping the spatial distribution of avalanches is one of the initial steps in avalanche management. In this study, geospatial modeling was performed

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 ...

Particle trajectories, velocities, accelerations and rotation rates in snow avalanches

Annals of Glaciology
Understanding the dynamics of snow avalanches is crucial for predicting their destructive potential and mobility. To gain insight into avalanche dynamics at a particle level, the AvaNode in-flow sensor system was developed.

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.
