, 2004 Snow avalanches represent a threat to societies in many countries of the world. In America, Asia, Australia, and Europe, several mountainous countries are affected by this type of natural hazard. People, housing areas, communication lines, ski areas, animals, and woodland are subjected to the threat of snow avalanches.

, 2001 Abstract Avalanches have long been a natural threat to humans in mountainous areas. At the end of the Middle Ages, the population in Europe experienced significant growth, leading to an intensive exploitation of upper valleys. At almost the same time, Europe’s climate cooled down considerably and severe winters became more common.

Thermal energy in dry snow avalanches [PDF]
The Cryosphere, 2015 Avalanches can exhibit many different flow regimes from powder clouds to slush flows. Flow regimes are largely controlled by the properties of the snow released and entrained along the path. Recent investigations showed the temperature of the moving snow

Risk analysis for landslides and snow avalanches. Example applications for snow avalanches [PDF]
, 1999 Prediction of snow avalanche occurrence and its run-out distance inherently involves many uncertainties. The main reason for the large uncertainties is that the mechanical behaviour of snow is extremely complicated, and other external factors that affect the problem, such the climate, wind direction, amount of snowfall, loading rate, etc.

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 ...

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 ...

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 ...

Estimation of soil redistribution rates due to snow cover related processes in a mountainous area (Valle d'Aosta, NW Italy) [PDF]
, 2012 Mountain areas are widely affected by soil erosion, which is generally linked to runoff processes occurring in the growing season and snowmelt period.
