    • 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 ...
