Review of meteorological data from Fonnbu 2009–2016
(NGI-rapport;20140053-05-TN, Research report, 2017-01-25)12 observed parameters are recalculated with a time step of 1 hour from the original raw data set of observed values with 10 minute time step. To form winter season data sets which would cover complete snow season, it was ... -
Review of spatial variability of snowpack properties and its importance for avalanche formation.
(Journal article, 2008)The seasonal snow cover is spatially variable. Spatial variability of layer properties is due to various external and internal process drivers interacting with terrain and ground cover during and after the deposition ... -
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 ... -
Risikomanagement in lawinenexponierten Gebieten Norwegens: Visionen im Lawinenschutz
(Chapter, 2017)Dieser Beitrag entstand anlässlich des Symposiums "VISIONS OF AVALANCHE PROTECTION" 27 - 28 April 2017 in Galtür, Tirol. -
Risk analysis for landslides and snow avalanches. Example applications for snow avalanches
(NGI-rapport;522051-01, Research report, 1999-12-23)Prediction of snow avalanche occurrence and its run-out distance inherently involves many uncertainties. The main reason for the large uncertainties is that the mechanical behaviour of snow is extremely complicated, and ... -
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 ... -
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 ... -
