    • On snow avalanche flow regimes: Inferences from observations and measurements. 

      Gauer, Peter; Issler, Dieter; Lied, Karstein; Kristensen, Krister; Sandersen, Frode (The International Snow Science Workshop (ISSW) Proceedings;, Chapter, 2008)
      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 the presence of an intermediate-density ...

    • Optimization and probabilistic calibration of avalanche block models 

      Gauer, Peter; Medina-Cetina, Zenon; Lied, Karstein; Kristensen, Krister (Journal article, 2009)
      The Norwegian Geotechnical Institute (NGI) has been performing full-scale avalanche tests at Ryggfonn in western Norway for more than 30 years. During those years, measurements from about three dozen dry-snow avalanches ...

    • Overrun length of avalanches overtopping catching dams: Cross-comparison of small-scale laboratory experiments and observations from full-scale avalanches 

      Faug, Thierry; Gauer, Peter; Lied, Karstein; Naaim, Mohamed (Journal article, 2008)
      Results from small-scale and full-scale experiments on avalanche–dam interactions are presented and compared. These experiments were analyzed with respect to the overrun length (i.e., the distance that the avalanche traveled ...

    • Possible erosion mechanisms in snow avalanches 

      Gauer, Peter; Issler, Dieter (Journal article, 2004)
      Snow erosion and entrainment processes in avalanches are classified according to their mechanisms, the flow regimes in which they occur, and their spatial position within the avalanche. Simple, but process-specific, models ...

    • Probabilistic calibration of avalanche block models. 

      Gauer, Peter; Medina-Cetina, Zenon; Lied, Karstein; Kristensen, Krister (The International Snow Science Workshop (ISSW) Proceedings;, Chapter, 2008)
      The Norwegian Geotechnical Institute (NGI) has been operating the full-scale avalanche test-site Ryggfonn in western Norway for more than 25 years. During those years, measurements from about three dozen dry-snow avalanches ...

    • Research Plan 2020–2022 

      Issler, Dieter; Jaedicke, Christian; Gauer, Peter; Gisnås, Kjersti; Frauenfelder, Regula; Salazar, Sean (NGI-Rapport;20200017-01-R, Research report, 2020-04-23)
      Snow avalanches are a significant natural hazard and common phenomenon in Norway. Each year, avalanches result in fatalities, evacuations, and interruptions or damage to infrastructure networks such as roads, railways, and ...

    • Research Plan 2023–2025 

      Tregaskis, Callum; Jaedicke, Christian; Gauer, Peter; Gisnås; Robinson, Kate; Issler, Dieter; Salazar, Sean; Vicari, Hervé; Frauenfelder, Regula (NGI-Rapport;20230100-01-R, Research report, 2023-05-19)
      Snow avalanches are a frequent and significant natural hazard in Norway. Each year, avalanche events result in fatalities, evacuations, interruptions, and damage to infrastructure networks such as roads, railways, and ...

    • Risikomanagement in lawinenexponierten Gebieten Norwegens: Visionen im Lawinenschutz 

      Gauer, Peter (Journal article, 2017)
      Dieser Beitrag entstand anlässlich des Symposiums "VISIONS OF AVALANCHE PROTECTION" 27 - 28 April 2017 in Galtür, Tirol.

    • Selected observations from avalanche measurements at the Ryggfonn test site and comparisons with observations from other locations 

      Gauer, Peter (The International Snow Science Workshop (ISSW) Proceedings;, Chapter, 2016)
      Selected observations from the full-scale avalanche test site Ryggfonn, Norway, like front velocity, runout distance, or pressure distributions, are presented and compared with observations from other locations. In this ...

    • Snow avalanche energy estimation from seismic signal analysis 

      Vilajosana, I.; Suriñach, E.; Khazaradze, G.; Gauer, Peter (Journal article, 2007)
      A method to determine the dissipated seismic energy into the ground by a down going avalanche is presented. Evaluation of the seismic energy is useful for avalanche size classification, model validation, and for characterization ...

    • The upgraded full-scale avalanche test-site Ryggfonn, Norway. 

      Gauer, Peter; Breien, Hedda; Issler, Dieter; Kristensen, Krister; Kronholm, Kalle; Lied, Erik; Lied, Karstein (The International Snow Science Workshop (ISSW) Proceedings;, Chapter, 2010)
      Measurements of full-scale avalanches are expensive and time consuming, but are indispensable to gain in-depth understanding of the flow behavior of avalanches. They are needed to crosscheck the scaling used in small-scale ...

    • The use of a numerical snow-drift model as a decision making tool in the planning of avalanche protection measures. 

      Gauer, Peter (The International Snow Science Workshop (ISSW) Proceedings;, Chapter, 2002)
      Blowing and' drifting snow is not only a major factor in the assessment of the acute avalanche danger, its contribution to the snow distribution also influences land-use planning. In many parts of alpine terrain end an ...

    • Überlegungen zur Designlawine von Lawinendämmen 

      Gauer, Peter (Chapter, 2023)

    • Vulnerability of houses and persons under avalanche impact – the avalanche at Longyearbyen on 2015-12-19 

      Issler, Dieter; Jónsson, Árni; Gauer, Peter; Domaas, Ulrik (The International Snow Science Workshop (ISSW) Proceedings;, Chapter, 2016)
      This study uses data from the avalanche that killed two persons and destroyed eleven essentially identical wood-frame houses in Longyearbyen, Svalbard, on 2015-12-19. The avalanche is back-calculated with a dynamical model ...
