Angle of repose experiments with snow: role of grain shape and cohesion
Journal of Glaciology, 2020 Snow appears as a granular material in most engineering applications. We examined the role of grain shape and cohesion in angle of repose experiments, which are a common means for the characterization of granular materials. The role of shape was examined

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.

Heterogeneous grain growth and vertical mass transfer within a snow layer under a temperature gradient [PDF]
The Cryosphere, 2023 Inside a snow cover, metamorphism plays a key role in snow evolution at different scales. This study focuses on the impact of temperature gradient metamorphism on a snow layer in its vertical extent.

Snow-Collection Mechanisms and the Capacities of Snow Fences [PDF]
Annals of Glaciology, 1989 The shapes of equilibrium lee drifts formed by snow fences are scaled in proportion to height of snow fences independent of the snow and weather conditions, even in small-scale models, but those of up-wind drifts are not.Field studies have been made of the snow-collection mechanisms of a snow fence.

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.

Wind conditions for snow cornice formation in a wind tunnel [PDF]
The Cryosphere, 2023 Snow cornices growing on the leeward side of mountain ridges are common in alpine and polar regions during snow seasons. These structures may crack and fall, leading to an increase in avalanche danger. Although cornice formation has been observed in wind

Mechanism and effects of snow accumulations and controls by lightweight snow fences [PDF]
Journal of Modern Transportation, 2016 This paper investigates the snowdrifts caused by lightweight fences along the lines on the flatland through the computational fluid dynamics method. The characteristic ambient flows around the solid fences and the porous fences with varied heights and bottom wind gaps are simulated in the numerical model, and the working mechanism of “interception” and

Acoustic emission signatures prior to snow failure
Journal of Glaciology, 2018 Snow slab avalanches are caused by cracks forming and propagating in a weak snow layer below a cohesive slab. The gradual damage process leading to the formation of the initial failure within the weak layer (WL) is still not entirely understood.
