Coupled Snow Cover and Avalanche Dynamics Simulations to Evaluate Wet Snow Avalanche Activity [PDF]
Journal of Geophysical Research: Earth Surface, 2018 We present physics‐based snowpack simulations for four snow seasons with detailed wet snow avalanche activity records. The distributed, spatially explicit simulations using the Alpine3D and SNOWPACK model show that the simulated snowpack in the release areas of documented wet snow avalanches often exhibits its first wetting of the season on the release

Distributed snow and rock temperature modelling in steep rock walls using Alpine3D [PDF]
The Cryosphere, 2017 In this study we modelled the influence of the spatially and temporally heterogeneous snow cover on the surface energy balance and thus on rock temperatures in two rugged, steep rock walls on the Gemsstock ridge in the central Swiss Alps.

Soil erosion and organic carbon export by wet snow avalanches [PDF]
, 2014 Many mountain belts sustain prolonged snow cover for parts of the year, although enquiries into rates of erosion in these landscapes have focused almost exclusively on the snow-free periods.

Influence of stress, temperature and crystal morphology on isothermal densification and specific surface area decrease of new snow [PDF]
The Cryosphere, 2014 Laboratory-based, experimental data for the microstructural evolution of new snow are scarce, though applications would benefit from a quantitative characterization of the main influences.

Automated snow avalanche release area delineation – validation of existing algorithms and proposition of a new object-based approach for large-scale hazard indication mapping [PDF]
Natural Hazards and Earth System Sciences, 2018 Snow avalanche hazard is threatening people and infrastructure in all alpine regions with seasonal or permanent snow cover around the globe. Coping with this hazard is a big challenge and during the past centuries, different strategies were developed.

Snow in a very steep rock face: accumulation and redistribution during and after a snowfall event
Frontiers in Earth Science, 2015 Terrestrial laser scanning was used to measure snow thickness changes (perpendicular to the surface) in a rock face. The aim was to investigate the accumulation and redistribution of snow in extremely steep terrain (>60°).
