Avalanche probability: Slab release and the effect of forest cover
Gauer, Peter (Lecture, 2018) -
Considerations on scaling behavior in avalanche flow along cycloidal and parabolic tracks
Gauer, Peter (Peer reviewed; Journal article, 2018)A simple scaling analysis using a simple mass block model supports observations and measurements on snow avalanches, that the maximum front-velocity of “major” avalanches scales with the total drop height of the track. ... -
Considerations on scaling behavior in avalanche flow: Implementation in a simple mass block model
Gauer, Peter (Peer reviewed; Journal article, 2020)Observations of runout distances combined with velocity measurements suggest that “major” dry-mixed avalanches show a scale invariance to the total drop height HSC. This is in accordance to the proposed upper-limit envelope ... -
Emerging insights into the dynamics of submarine debris flows
Elverhøi, Anders; Issler, Dieter; De Blasio, Fabio V.; Ilstad, Trygve; Harbitz, Carl Bonnevie; Gauer, Peter (Journal article, 2005)Recent experimental and theoretical work on the dynamics of submarine debris flows is summarized. Hydroplaning was first discovered in laboratory flows and later shown to likely occur in natural debris flows as well. It ... -
Estimates on the reach of the powder part of avalanches
Gauer, Peter (Lecture, 2018)Avalanche observations from Norway, Austria and Switzerland, which distinguish between dense (fluidized) flow and powder part, are analyzed to obtain probability information about the reach of the powder part. The analysis ... -
Four decades of observations from NGI’s full-scale avalanche test site Ryggfonn—Summary of experimental results
Gauer, Peter; Kristensen, Krister (Journal article, 2016) -
Inferences on Mixed Snow Avalanches from Field Observations
Issler, Dieter; Gauer, Peter; Schaer, Mark; Keller, Stefan (Peer reviewed; Journal article, 2019)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, erosion modes, and ... -
Maximum frontal speeds, alpha angles and deposit volumes of flowing snow avalanches
McClung, D.M.; Gauer, Peter (Peer reviewed; Journal article, 2018)Approximate maximum frontal speeds from 89 snow avalanches were analyzed to yield probabilistic estimates of maximum speed scaled with path length parameters. In addition to speeds, 88 companion values of runout for the ...
