Natural Hazards / Automatic detection of avalanches: evaluation of three different approaches [PDF]

, 2017
Nicht verf\ufcgbarAutomated detection of snow avalanches is an important tool for avalanche forecasting and for assessing the effectiveness of avalanche control measures at bad visibility.

Mass Addition to Timpanogos Rock Glacier: Debris‐Covered Snow and the Importance of Interannual Variability in Headwall Erosion and Climate

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract The processes of ice incorporation into rock glaciers have been difficult to quantify in both permafrost and non‐permafrost conditions. Here, we develop a numerical model that regardless of the presence of permafrost, reveals how debris eroded from hillslopes and deposited on snow can add ice mass to rock glaciers in pulses.

Towards a model of glide-snow avalanche occurrence using in-situ soil and snow measurements

Journal of Glaciology
Glide-snow avalanches release at the soil-snow interface and are currently difficult to predict. This is mostly due to a limited understanding of the release process and a lack of data, particularly of the snowpack and underlying soil conditions prior to

High‐resolution radar measurements of snow avalanches [PDF]

Geophysical Research Letters, 2013
Two snow avalanches that occurred in the winter 2010–2011 at Vallée de la Sionne, Switzerland, are studied using a new phased array FMCW radar system with unprecedented spatial resolution. The 5.3 GHz radar penetrates through the powder cloud and reflects off the underlying denser core. Data are recorded at 50 Hz and have a range resolution better than

Assessment of Snow Cover Fraction Parameterizations for High Resolution Snowpack Reanalyses

Hydrological Processes, Volume 40, Issue 4, April 2026.
Recent advances in estimating snow water equivalent (SWE) use remotely sensed snow‐covered area data, especially in mountains where precipitation is uncertain. The process relies on a scale‐dependent snow cover fraction (SCF) parameterization. At 100 m resolution, an asymptotic parameterization performed best, reducing SCF RMSE to 16% when assimilating

Size of snow particles in a powder-snow avalanche [PDF]

, 2009
The size of the snow particles involved in a powder-snow avalanche is a key parameter of the local dynamic of the flow. An experimental device has been realized to collect snow particles within powder-snow avalanches. Snow particles have been captured in

Twenty‐Three Years of Landslide Activity in the European Alps–Part 2: Investigating Triggers and the Impacts of Meteorological Change on Landslide Occurrences

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 4, April 2026.
Abstract Landslides represent one of the most devastating natural hazards in mountainous regions, posing significant threats to human safety, infrastructure and ecosystems. It is well established that there is a connection between meteorological factors and landslide occurrences but the mechanisms of these interactions and the impacts of climatic ...

The Performance Gains of Assimilating Limited Information Into a Fully Distributed Snowpack Model Depend on Model Complexity and Input Data Quality

Water Resources Research
Estimating snowpack conditions in mountainous regions is critical for water resource management, flood forecasting, and avalanche hazard mitigation. However, most snowpack observations lack either spatial or temporal resolution, while estimates from ...

Glide-snow avalanche characteristics at different timescales extracted from time-lapse photography

Annals of Glaciology
Glide-snow avalanches release due to a loss of friction at the snow–ground interface, which can result in large avalanches that endanger infrastructure in alpine regions.
