Micro-mechanical insights into the dynamics of crack propagation in snow fracture experiments
Scientific Reports, 2021 Dry-snow slab avalanches result from crack propagation in a highly porous weak layer buried within a stratified and metastable snowpack. While our understanding of slab avalanche mechanisms improved with recent experimental and numerical advances ...

On the correlation between a sub-level qualifier refining the danger level with observations and models relating to the contributing factors of avalanche danger [PDF]
Natural Hazards and Earth System Sciences, 2022 Forecasting avalanche danger at a regional scale is a largely data-driven yet also experience-based decision-making process by human experts. In the case of public avalanche forecasts, this assessment process terminates in an expert judgment concerning ...

Fuzzy modelling of powder snow avalanches [PDF]
, 2004 This paper examines powder snow avalanches by introducing a predetermined degree of variation, or fuzziness, in model parameters. Given a value of vagueness in the parameters, fuzzy set theory makes it possible to evaluate the vagueness in the results ...
