Rheology of a wet, fragmenting granular flow and the riddle of the anomalous friction of large rock avalanches
(Journal article, 2009)The effective friction coefficient of rock avalanches diminishes gradually as a function of the avalanche volume. Large rock avalanches can reach run-out distances as long as ten times the fall height, despite the fact ... -

Risk management with mandatory upper risk threshold in the world's largest mountaineering school
(The International Snow Science Workshop (ISSW) Proceedings;, Chapter, 2013)At the beginning of the new millennium, the DAV Summit Club, the commercial mountaineering school of the German Alpine Club and world’s largest provider of commercial mountaineering has developed a risk frame work with ... -
Road traffic and avalanches - methods for risk evaluation and risk management
(Journal article, 2003)This paper considers the methods for risk analysis and management in connection with avalanches and road traffic. Examples with calculations of encounter probability and quantification of uncertainty are given, along with ... -
Roads at risk: Traffic detours from debris flows in southern Norway
(Journal article, 2015)Globalisation and interregional exchange of people, goods, and services has boosted the importance of and reliance on all kinds of transport networks. The linear structure of road networks is especially sensitive to natural ... -

Rock-avalanche hazard in Møre & Romsdal, western Norway
(NGI Publication;203, Chapter, 1998)Flood waves generated by large rock avalanches have caused major disasters in Norway. Many of these events are restricted to a relatively limited zone in the counties Møre & Romsdal and Sogn & Fjordane. Geological studies ... -
Rows of vertical steel-silos filled with debris - an effective space-saving avalanche defense structure.
(Chapter, 2002)Multiplate steel configurations, primarily used for road tunnels and culverts, are introduced as effective, flexible and space-saving avalanche defence structures. Silos of specified height and profile are filled with ... -
A Rule Based Risk Management System Based on Maps and Danger Level
(The International Snow Science Workshop (ISSW) Proceedings;, Chapter, 2012)After a tragic accident where 16 soldiers were killed in an avalanche during a military exercise in 1986, the Norwegian Armed Forces took several steps to ensure the safety of soldiers. The result is a risk management ... -
"Safe haven" at road sides near avalanche prone sites
(The International Snow Science Workshop (ISSW) Proceedings;, Chapter, 2008)Snow avalanches cause threat to road traffic in mountainous areas in Iceland in wintertime. One or more vehicles are hit by avalanches every year but last year’s no fatal accidents due to snow avalanches have been reported. ... -
Safran/Crocus/Mepra models as an helping tool for avalanche forecasters
(NGI Publication;203, Chapter, 1998)To describe the great variability of the snow pack and to predict the avalanche risk in the French Alps and Pyrenees massifs, the «Centre d'Etudes de la Neige» (C.E.N.) of METEO-FRANCE has developed an automatic chain of ... -
