Abstract Observational and experimental evidence suggests that it is important to explicitly account for the fluidized flow regime in avalanche hazard mapping due to its high mobility, intermediate density and high velocity. We explore the differences from conventional runout modelling by implementing an extension of the Norem–Irgens–Schieldrop (NIS) rheology in a simple mass-point model. When the dispersive stresses and the excess pore pressure equal the overburden pressure, the flow height… Expand
Comments on avalanche flow models based on the concept of random kinetic energy
ABSTRACT In a series of papers, Bartelt and co-workers developed novel snow-avalanche models in which random kinetic energy (RKE) RK (a.k.a. granular temperature) is a key concept. The earliestExpand
Modeling mass‐dependent flow regime transitions to predict the stopping and depositional behavior of snow avalanches
[1] How terrain, snow cover properties, and release conditions combine to determine avalanche speed and runout remains the central problem in avalanche science. Here we report on efforts toExpand
Three flow regimes in mixed snow avalanches ( I ) : Field observations
Three mixed-snow avalanches of widely different sizes, which occurred in the winter 1995 in Switzerland, showed a number of interesting phenomena in an unusually clear fashion. In particular, oneExpand
On Snow Avalanche Flow Regimes: Inferences from Observations and Measurements
Mixed dry-snow avalanches are commonly thought to consist of a dense core and a dilute suspension layer, even though observations and measurements from Canada and Russia have long indicated theExpand
The relation between dilatancy, effective stress and dispersive pressure in granular avalanches
Here we investigate three long-standing principles of granular mechanics and avalanche science: dilatancy, effective stress and dispersive pressure. We first show how the three principles areExpand
Inferences on Mixed Snow Avalanches from Field Observations
Observations of the deposits, flow marks, and damages of three mixed-snow avalanches of widely different size were analyzed with regard to flow regimes, velocities, pressures, densities, flow depths,Expand
Formation of levees and en-echelon shear planes during snow avalanche run-out
Abstract Snow avalanches often form levees and en-echelon shear planes in the run-out zone. We describe the formation of these depositional structures using a simple model that accounts for the roleExpand
Three-dimensional and real-scale modeling of flow regimes in dense snow avalanches
Snow avalanches cause fatalities and economic loss worldwide and are one of the most dangerous gravitational hazards in mountainous regions. Various flow behaviors have been reported in snowExpand
Multivariate parameter optimization for computational snow avalanche simulation
Abstract Snow avalanche simulation software is a commonly used tool for hazard estimation and mitigation planning. In this study a depth-averaged flow model, combining a simple entrainment andExpand
Perspectives on Snow Avalanche Dynamics Research
As an introduction for non-specialists to the Special Issue on snow avalanche dynamics, this paper first outlines how understanding the dynamics of snow avalanches can contribute to reducing risk forExpand


A continuum model for calculating snow avalanche velocities
Constitutive equations for the properties of snow in avalanches are proposed. These are based on the equations for a modified Criminale Ericksen Filbey fluid which shows a close agreement toExpand
A Two–Parameter Model of Snow–Avalanche Motion
Voellmy’s (1955) method for computing the run-out distance of a snow avalanche includes an unsatisfactory feature: the a priori selection of a midslope reference where the avalanche is assumed toExpand
Inferences on flow mechanisms from snow avalanche deposits
Abstract The deposit structure of 20 very small to large avalanches that occurred in the Davos area, eastern Swiss Alps, during winters 2004/05 and 2005/06 was investigated. Snow-cover entrainmentExpand

Avalanche measurements and observations, which were carried out at the Ryggfonn test-site, Norway, on 16 April 2005, are analyzed. The data include pulsed Doppler radar measurements, impact pressureExpand
Ping-pong ball avalanche at a ski jump
Abstract Three dimensional granular flow experiments were carried out on a ski jump with 300,000 ping-pong balls. Since the air drag was a large effect, the flow arrived at a steady state within aExpand
