Restoration of seagrass habitats: Effects of artificial and natural sediments on the development of transplanted eelgrass (Zostera marina)
(Peer reviewed; Journal article, 2023) -
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 ... -
Review of the Reclamation Techniques for Acid-Generating Mine Wastes upon Closure of Disposal Sites
(Peer reviewed; Journal article, 2016)Acid mine drainage (AMD) remains a major environmental challenge for the mining industry. The preferred options for effectively limiting the environmental impact of AMD consist in controlling the reactions through the use ... -
Revisiting interpretation of relative density from shallow depth CPTs in sand
(Peer reviewed; Journal article, 2022) -
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
(Journal article, 2017)Dieser Beitrag entstand anlässlich des Symposiums "VISIONS OF AVALANCHE PROTECTION" 27 - 28 April 2017 in Galtür, Tirol. -
Risk analyses in excavation and foundation work

Risk Analysis of Earthquake-Induced Submarine Slope Failure
(Chapter, 2015) -
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 assessment and design of prevention structures for enhanced tsunami disaster resilience (RAPSODI) - Euro-Japan collaboration
(Journal article, 2016)The 2011 Tōhoku event showed the massive destruction potential of tsunamis. The Euro-Japan “Risk assessment and design of prevention structures for enhanced tsunami disaster resilience (RAPSODI)” project aimed at using ... -
Risk assessment of terrestrial transportation infrastructures exposed to extreme events
(Peer reviewed; Journal article, 2021) -
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 ... -
Roads with underlying tar asphalt - spreading, bioavailability and toxicity of their polycyclic aromatic hydrocarbons

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 ...
