Propagation of weak layer failure in snow slab avalanche release: analytical solutions for a compliant interface with finite softening
Johan Gaume, Francis Meloche, Ingrid Reiweger +1
Snow slab avalanches are among the most dangerous hazards in mountain regions. Recent numerical, field, and laboratory studies have renewed interest in shear-failure interpretation…
Modeling crack arrest in snow slab avalanches -- towards estimating avalanche release sizes
Francis Meloche, Grégoire Bobillier, Louis Guillet +3
Dry-snow slab avalanches are considered to be the most difficult to predict, yet the deadliest avalanche types. The release of snow slab avalanches starts with a initial failure in…
A theoretical framework for dynamic anticrack and supershear propagation in snow slab avalanches
Marin Siron, Bertil Trottet, Johan Gaume
(Shortened abstract) Snow slab avalanches release after the failure and collapse of a weak layer buried below a cohesive snow slab. This results in the propagation of a subsidence,…
A Depth-Averaged Material Point Method for Shallow Landslides: Applications to Snow Slab Avalanche Release
Louis Guillet, Lars Blatny, Bertil Trottet +1
Shallow landslides pose a significant threat to people and infrastructure. While often modeled based on limit equilibrium analysis, finite or discrete elements, continuum particle-…
