    • Slushflow Formation, Flow Regimes and Consequences (Short Version) 

      Hestnes, Erik; Bakkehøi, Steinar; Kristensen, Krister (The International Snow Science Workshop (ISSW) Proceedings;, Chapter, 2012)
      The term ‘slushflow’ was introduced by Washburn and Goldthwait (1958). Eight people perished in slushflows during the winters 2010 and 2011 in Norway, five in backcountry, two in their home and one truck-driver. Buildings, ...

    • Snow avalanche forecasting in Iceland and Norway 

      Kristensen, Krister (NGI-rapport;581250-02, Research report, 1996-01-29)
      This document describes local avalanche warning and forecasting operations in Iceland and Norway, with the focus on forecasting as a preventive measure for communities with threatened habitations. The objective of an ...

    • Snow avalanche speed determination using seismic methods 

      Vilajosana, I.; Khazaradze, G.; Suriñach, E.; Lied, Erik; Kristensen, Krister (Journal article, 2007)
      We present a new method to determine the average propagation speed of avalanches using seismic techniques. Avalanche propagation speeds can reach 70 m/s and more, depending on a wide range of factors, such as the characteristics ...

    • Snow-creep pressure on masts 

      Larsen, Jan Otto; Laugesen, Jens; Kristensen, Krister (Journal article, 1989)
      Snow-pressure measurements have been carried out on two masts at the NGI avalanche station in Grasdalen, western Norway. These two tubular masts have diameters of 0.22 and 0.42 m, respectively, and are situated on a 25° ...
