Fitting avalanche-dynamics models with documented events from the Col du Lautaret site (France) using the conceptual approach
TL;DR: Three conceptual avalanche-dynamics models are tested by comparing their predictions to 14 documented avalanches observed at the Lautaret Pass (France), and only two of them provided correct estimates of avalanche velocity.

Plasticity and geophysical flows: A review
TL;DR: In this article, a review of the use of the concept of plasticity in geophysical fluid dynamics is presented, focusing on the role of pore pressure and friction in the bulk dynamics.

Can we learn more from the data underlying the statistical α–β model with respect to the dynamical behavior of avalanches?
TL;DR: In this article, the runout distance equations were found by regression analysis, correlating the longest registered runout distances of several hundred avalanche paths with a selection of topographic parameters, which raised reasonable doubt whether the classical ansatz for the retarding acceleration of snow avalanches with additive terms involving Coulomb-friction and a velocity-squared dependency is adequate for a physically-based model.

Characterization of avalanche loading on impacted structures: a new approach based on inverse analysis
TL;DR: In this article, the authors focus on the feasibility of using the inverse method to quantify the action of the avalanche from its effects on realistic structures rather than from sensors placed directly in the flow.

TL;DR: In this article, two similarity solutions are found for the motion of a finite mass of material released from rest on a rough inclined plane, and the linear stability of the similarity solutions is studied.

A Two–Parameter Model of Snow–Avalanche Motion
TL;DR: In this article, a differential equation is derived on the premise that the only logical reference is the starting position of the avalanche, and the equation is solved numerically for paths of complex geometry, and solutions are based on two parameters: a coefficient of friction μ; and a ratio of avalanche mass-to-drag, M⁄D.
Flow, flow transition and runout distances of flowing avalanches
TL;DR: In this article, a quasi-one-dimensional model of flowing avalanches is presented, which is a further development of that used in the Swiss Guidelines for practitioners, and it is shown that shearing in avalanche movement is concentrated near the ground and that, due to the geometrical roughness of the ground, a flow resistance proportional to the square of velocity must be taken into account in addition to dry friction.
