  Information - NH7.01 Snow cover, snow avalanche formation and dynamics, risk assessment

Event Information
Snow avalanches threaten mountain communities worldwide. The first part of
the session is devoted to the latest results on snow avalanche formation
from field, laboratory and numerical studies. Key factors influencing snow
avalanche formation are snow cover characteristics and meteorological
boundary conditions (precipitation, wind, radiation etc.). Snow avalanche
formation covers a wide range of scales from the bonds between snow
crystals to the release of a snow slab avalanche. The practical application
of avalanche formation is avalanche forecasting. Any contributions on
mechanical properties and texture of snow, snow cover simulation,
contributing factors (including drifting and blowing snow), spatial
variability, snow slab release mechanics and avalanche forecasting are
welcome. This part of the session aims to improve our understanding of the
formation process and to foster the application to avalanche forecasting.
The second part of this session is dedicated to the movement and effect of
flowing snow and powder snow avalanches. Emphasis is placed on flow
dynamics, experimental techniques and practical application of numerical
models to predict avalanche run-out distances, flow velocities, interaction
with structures and impact pressures for hazard assessment and mitigation.
The aim of the second part of this session is to present recent
developments in the area of avalanche hazard/risk assessment and
mitigation, with special attention paid to both methodological and
legislative aspects, as well to the presentation of real world problem
solutions and lessons learnt.
