Quality assessment of a new in-mould slurry deposition method for triaxial specimen reconstitution of clean and silty sands
(Peer reviewed; Journal article, 2019) -
Rainfall-induced landslides in Quaternary soils in Norway
(Journal article, 2016)Increased intensity of rainfall in later years seems to result in increased frequency of rainfall-induced landslides in natural slopes with glacial Quaternary deposits, which cover large parts of Norway. Many slides hit ... -
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 ... -
Reducing Uncertainty and Confronting Ignorance about the Possible Impacts of Weathering Plastic in the Marine Environment
(Peer reviewed; Journal article, 2017)Plastic in the global oceans fulfills two of the three conditions for pollution to pose a planetary boundary threat because it is causing planetary-scale exposure that is not readily reversible. Plastic is a planetary ... -
REDWIN – REDucing cost in offshore WINd by integrated structural and geotechnical design
(Peer reviewed; Journal article, 2018)The cost of offshore wind energy production has to be reduced continuously to improve its competitiveness compared to other energy sources. To contribute to this goal, a 4- year research project REDWIN – REDucing cost of ... -
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 Identification, Characterization and Monitoring of Erosional Processes
(NGI Rapport;20170031-03-R, Report, 2018-03-21)Remote sensing techniques and geophysical techniques have enabled the collection of vital information on geotechnical, hydrogeological, and environmental processes. These techniques may offer improvements over traditional ... -
Reservoir assessment of Middle Jurassic sandstone-dominated formations in the Egersund Basin and Ling Depression, eastern Central North Sea
(Peer reviewed; Journal article, 2019)Reservoir quality assessment was conducted from petrophysical analysis and rock physics diagnostics on 15 wells penetrating Middle Jurassic sandstone reservoir formations in different regions of the eastern Central North ... -
Resistivity and chargeability survey for tunnel investigation: a case study on toxic black shale in Norway
(Journal article; Peer reviewed, 2017)In the past few years, the focus on Alum shale hazards and the need for efficient mapping tools have increased in Norway. Alum shale is highly toxic and poses a substantial obstacle to infrastructure development such as ... -
Response of marine benthic fauna to thin-layer capping with activated carbon in a large-scale field experiment in the Grenland fjords, Norway
(Peer reviewed; Journal article, 2017)A field experiment with thin-layer capping was conducted in the Grenland fjords, Norway, for remediation in situ of mercury and dioxin-contaminated sediments. Experimental fields at 30 and 95 m depth were capped with (i) ... -
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 ... -
Risk analyses in excavation and foundation work
(Lecture, 2016) -
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 ... -
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 ... -
Sand textural control on shear-enhanced compaction bands in poorly-lithified sandstone
(Journal article, 2014)Sand textural control on SECB (shear-enhanced compaction band) formation is analyzed combining field observations, detailed material characterization and mechanical testing for poorly lithified sandstone units in Provence ... -
Scale of Fluctuation for Geotechnical Probabilistic Analysis
