    • Global warning reduces the consequences of slushflows 

      Hestnes, Erik; Bakkehøi, Steinar; Jaedicke, Christian (Chapter, 2017)
      Most recentpublicationson natural hazards, if they mention slushflows at all, state that their impact onmankind will increase. However, milder weather, shorter winters, less snow and rise of the snowline will mainly shift ...

    • Global warning reduces the consequences of snow-related hazards 

      Hestnes, Erik; Jaedicke, Christian (Lecture, 2018)
      Most recent publications dealing with consequences related to avalanches and slushflows state that their impact on mankind will increase. That is a highly debatable statement. Milder weather, shorter winters, less snow and ...

    • Identification of slushflow situations from regional weather models 

      Jaedicke, Christian; Høydal, Øyvind Armand; Midtbø, Knut Helge (Norwegian Geotechnical Institute;, Chapter, 2013)
      Slushflows are known phenomena that cause significant problems for settlements and infrastructure in Norway. Even though single events in the same location are rather rare compared to avalanches, slushflows do occur annually ...

    • Impacts of extreme weather events on transport infrastructure in Norway 

      Frauenfelder, Regula; Solheim, Anders; Isaksen, Ketil; Romstad, Bård; Dyrrdal, Anita Verpe; Ekseth, Kristine; Skaland, Reidunn Gangstø; Harbitz, Alf; Harbitz, Carl Bonnevie; Haugen, Jan Erik; Hygen, Hans Olav; Haakenstad, Hilde; Jaedicke, Christian; Jónsson, Árni; Klæboe, Ronny; Ludvigsen, Johanna; Meyer, Nele Kristin; Rauken, Trude; Sverdrup-Thygeson, Kjetil (Journal article, 2016)

    • The influence of drifting snow on the location of glaciers on western Spitsbergen, Svalbard 

      Jaedicke, Christian; Gauer, Peter (Journal article, 2005)
      On western Spitsbergen, Svalbard, the amount of winter precipitation is insufficient to maintain the present-day mass balance of the local glaciers. Additional snow mass must be added to the precipitation to reach the ...

    • Integrated database for rapid mass movements in Norway 

      Jaedicke, Christian; Lied, Karstein; Kronholm, Kalle (Journal article, 2009)
      Rapid gravitational slope mass movements include all kinds of short term relocation of geological material, snow or ice. Traditionally, information about such events is collected separately in different databases covering ...

      Jaedicke, Christian; Lied, Karstein; Juvet, Halvor; Kronholm, Kalle (The International Snow Science Workshop (ISSW) Proceedings;, Chapter, 2006)
      Rapid mass movements include all kinds of slides in geological material, snow or ice. Traditionally, information about such events is collected separately in different databases covering selected geographical regions and ...

    • Integrated database for rapid mass movements in Norway. 

      Jaedicke, Christian; Lied, Karstein; Juvet, Halvor; Kronholm, Kalle (The International Snow Science Workshop (ISSW) Proceedings;, Chapter, 2006)
      Rapid mass movements include all kinds of slides in geological material, snow or ice. Traditionally, information about such events is collected separately in different databases covering selected geographical regions and ...

    • Local avalanche warning in Europe 

      Jaedicke, Christian; Studeregger, Arnold; Monti, Fabiano; Dellavedova, Paola; Stoffel, Lukas; Azzarello, Sergio; Garcia, Carles; Molné, Toni; Bellido, Guillem Martín (Lecture, 2018)
      Avalanche exposed settlements, communication lines, ski resort operations, construction sites, tourism and professional guiding are only few examples of activities in the mountains where an active risk management requires ...

    • Longyearbyen, Svalbard - Vulnerability and risk management of an arctic settlement under changing climate - a challenge to authorities and experts 

      Hestnes, Erik; Bakkehøi, Steinar; Jaedicke, Christian (The International Snow Science Workshop (ISSW) Proceedings;, Chapter, 2016)
      Longyearbyen, the administrative centre of the Svalbard archipelago, is facing most types of natural hazards under a changing Arctic climate. The catastrophic avalanche in December 2015 led NGI to review our professional ...

    • Norge - et overraskende snøskred-land 

      Jaedicke, Christian; Kronholm, Kalle (Journal article, 2008)
      Det er ikke helt passende å påstå at vestlendinger, nordlendinger og finnmarkinger er forskjellige av natur. Men snøskredene i de tre regionene er åpenbart forskjellige: Skred utløses ofte av nedbør på Vestlandet, av ...

    • Regional avalanche warning in Norway, a new concept for a large country 

      Jaedicke, Christian; Bakkehøi, Steinar; Sandersen, Frode; Brattlien, Kjetil; Solheim, Anders (The International Snow Science Workshop (ISSW) Proceedings;, Chapter, 2008)
      Norway encompasses 324 000 km2 of land area of which ca. 7 % are mountainsides steeper than 30 degrees. The country extends approximately 1700 km from south to north and features extreme variations in normal precipitation ...

    • Remote sensing of avalanches in northern Norway using Synthetic Aperture Radar 

      Malnes, Eirik; Eckerstorfer, Markus; Larsen, Yngvar; Frauenfelder, Regula; Jónsson, Árni; Jaedicke, Christian; Solbø, Stian A. (The International Snow Science Workshop (ISSW) Proceedings;, Chapter, 2013)
      We present results from using synthetic aperture radar data (SAR) to analyse three avalanches in the county of Troms in northern Norway during the late snow season 2013. During a persistent polar low pressure activity at ...

    • Snow mass quantification and avalanche victim search by ground penetrating radar 

      Jaedicke, Christian (Journal article, 2003)
      Ground penetrating radar (GPR) systems can be used in many applications of snow and ice research. The information from the GPR is used to identify and interpret layers, objects and different structures in the snow. A ...

    • The snowdrift pattern around a small hill in the High Arctic 

      Jaedicke, Christian; Thiis, Thomas K.; Bang, Børre (Chapter, 2000)
      The snow distribution in complex terrain is important for the planning of infrastructure, so that large snow depths can be avoided in residential areas and in connection with roads and railroads. Numerical models can give ...
