This session is devoted to the dynamics of dense and powder snow avalanches and their accompanying transitional regimes. One focus is their interaction with, and impact on, vulnerable elements, such as buildings, protection dams, forests, and roads. We welcome novel contributions from field, laboratory and numerical studies on topics including, but not limited to, avalanche dynamics and related processes, physical vulnerability of structures impacted by snow avalanches, avalanche hazard zoning and avalanche mitigation strategies.

Furthermore, we solicit novel contributions from the field of granular flows, viscoplastic flows, density currents, turbulent flows, as well as contributions from other gravity flows communities, which can improve our understanding and modeling of snow avalanche propagation and their interaction with natural or man-made structures.

While the main focus of this session is on snow avalanche dynamics from basic knowledge to mitigation strategies, it is closely linked to session 'CR3.01 Snow avalanche formation: from snow mechanics to avalanche detection’ which addresses avalanche formation, detection and forecasting.
