Wet-snow avalanche interaction with a deflecting dam: field observations and numerical simulations in a case study [PDF]

open access: yesNatural 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]

open access: yesThe 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 ...

A Study on Avalanche-Triggering Factors and Activity Characteristics in Aerxiangou, West Tianshan Mountains, China

open access: yesAtmosphere, 2023
Through analyzing the triggering factors and activity characteristics of avalanches in Aerxiangou in the Western Tianshan Mountains, the formation and disaster-causing process of avalanches were studied to provide theoretical support and a scientific ...

Can model-based avalanche forecasts match the discriminatory skill of human danger-level forecasts? A comparison from Switzerland [PDF]

open access: yesNatural Hazards and Earth System Sciences
In 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 ...

QUANTIFICATION OF ECONOMIC AND SOCIAL RISKS OF DEBRIS FLOWS FOR THE BLACK SEA COASTAL REGION OF THE NORTH CAUCASUS

open access: yesGeography, Environment, Sustainability, 2014
Debris flows are the most frequent and disastrous natural hazards among other exogenic processes at the Black Sea coastal region of the North Caucasus. Numerous debris flow releases are reported every year between Novorossiysk and Krasnaya Polyana.

Thermal energy in dry snow avalanches [PDF]

open access: yesThe 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

Spatial Variability of Snow Water Equivalent – The Case Study from the Research Site in Khibiny Mountains, Russia

open access: yesJournal of Hydrology and Hydromechanics, 2019
The aim of the investigation was assessment of spatial variability of the characteristics of snowpack, including the snow water equivalent (SWE) as the main hydrological characteristic of a seasonal snow cover.

Prediction of avalanches on the basis of the 27‐day Solar activity variations

open access: yesЛëд и снег, 2015
Many natural processes on the Earth are the cyclic ones and they are self-sustaining within a system of the Sun–Earth relations. To verify our hypothesis on a cyclic occurrence of the avalanche processes and to estimate a possibility to predict ...

Infrasound array criteria for automatic detection and front velocity estimation of snow avalanches: towards a real-time early-warning system [PDF]

open access: yesNatural Hazards and Earth System Sciences, 2015
Avalanche risk management is strongly related to the ability to identify and timely report the occurrence of snow avalanches. Infrasound has been applied to avalanche research and monitoring for the last 20 years but it never turned into an operational ...

Automated detection of snow avalanche deposits: segmentation and classification of optical remote sensing imagery [PDF]

open access: yesNatural Hazards and Earth System Sciences, 2012
Snow avalanches in mountainous areas pose a significant threat to infrastructure (roads, railways, energy transmission corridors), personal property (homes) and recreational areas as well as for lives of people living and moving in alpine terrain.
