Detrainment and braking of snow avalanches interacting with forests [PDF]
Natural Hazards and Earth System Sciences, 2022 Mountain forests provide natural protection against avalanches. They can both prevent avalanche formation in release zones and reduce avalanche mobility in runout areas.

Effects of Climate Change on Avalanche Accidents and Survival
Frontiers in Physiology, 2021 Avalanches are major natural hazards in snow-covered mountains, threatening people and infrastructure. With ongoing climate change, the frequency and types of snow avalanches may change, affecting the rates of avalanche burial and survival. With a wetter

Wet-snow avalanche interaction with a deflecting dam: field observations and numerical simulations in a case study [PDF]
Natural Hazards and Earth System Sciences, 2012 In avalanche-prone areas, deflecting dams are widely used to divert avalanches away from endangered objects. In recent years, their effectiveness has been questioned when several large and multiple avalanches have overrun such dams.

The mechanical origin of snow avalanche dynamics and flow regime transitions [PDF]
The Cryosphere, 2020 Snow avalanches cause fatalities and economic damage. Key to their mitigation is the understanding of snow avalanche dynamics. This study investigates the dynamic behavior of snow avalanches, using the material point method (MPM) and an elastoplastic ...

Can model-based avalanche forecasts match the discriminatory skill of human danger-level forecasts? A comparison from Switzerland [PDF]
Natural Hazards and Earth System SciencesIn recent years, physics-based snowpack models combined with machine-learning techniques have gained momentum in public avalanche forecasting. When integrated with spatial interpolation methods, these approaches enable fully model-driven predictions of ...

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 ...

Looking beyond the powder/dense flow avalanche dichotomy [PDF]
, 2018 Köhler et al. (2018) deploy a high spatial and temporal resolution GEODAR radar system to reveal the inside of snow avalanches over the entire slope.
