Prediction of slushflow hazard based on data from local meteorological stations.
(The International Snow Science Workshop (ISSW) Proceedings;, Chapter, 2010)Seeking objective criteria for slushflow prediction and warning, meteorological data has been recorded at two slushflow sites in Rana District, North Norway, during a 10 years period. The two starting zones were equipped ... -
Probabilistic calibration of avalanche block models.
(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 ... -
Probabilistic Seismic Hazard Analysis for Offshore Bangladesh Including Fault Sources
(Chapter, 2018)This paper presents a probabilistic seismic hazard analysis (PSHA) for a site offshore Maheshkhali Island, Bangladesh. The tectonic setting of the area is complex, and the PSHA includes active crustal faults, megathrust ... -
Quantitative risk analysis for evaluation of avalanche protection projects
(NGI Publication;203, Chapter, 1998)Questions on optimum protection measures have always been bound to economic considerations. This involves a comprehensive investigation and analysis of the effect of avalanche protection measures with an appropriate concept ... -
Radar measurements of snow avalanche full scale experiment in Ryggfonn.
(NGI Publication;203, Chapter, 1998)At the full scale experiment site of NG! in Ryggfonn, avalanche velocities and forces have been measured through 15 years. In April 1997 an Austrian developed INW pulsed Doppler radar was used to measure avalanche velocities ... -
Rate effect of piezocone testing in two soft clays
(Chapter, 2018)The Onsøy and Sarapuí II soft clays have been studied for a number of years. In particular, piezocone tests with different rates have been conducted at both sites. Since the plasticity index and the coefficient of ... -
Recommendation on how avoid Interference Issues in companion and organized avalanche rescue
(The International Snow Science Workshop (ISSW) Proceedings;, Chapter, 2013)Electronic avalanche rescue devices such as 457kHz transceivers and Recco are today the primary search tools in companion and organized rescue. The requirement for a long receive range in order to shorten rescue time asks ... -
Reducing Impact of Vibrations from Compaction on Slope Stability

Regional avalanche warning in Norway, a new concept for a large country
(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 ... -
Reliability-based approach for robust geotechnical design
(Chapter, 2017)Although geotechnical engineers have to deal with uncertainty and risk all the time, it is not common to talk about uncertainties and risk in the profession. Uncertainties are often addressed indirectly through the choice ... -
Remote sensing of avalanches in northern Norway using Synthetic Aperture Radar
(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 ... -
Remote-Sensing Derived Avalanche Inventory Data
(The International Snow Science Workshop (ISSW) Proceedings;, Chapter, 2012)Every year snow avalanches pose a significant threat to transportation infrastructure. The societal demand to minimize closures of the main transport network while maintaining an acceptable level of personal safety at the ... -
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 of Earthquake-Induced Submarine Slope Failure

Risk assessment and dams – Recent developments and applications
(Chapter, 2019)Increasingly, society and standards require "risk-informed" decisions. The paper demonstrates the benefits of implementing reliability and risk concepts in dam engineering as a complement to conventional deterministic ... -
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 ... -
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 ...
