Comparison of snow pressure measurements and theoretical predictions
(NGI-rapport;58110-03, Research report, 1985-02-01)Measurements of snow pressures from the centre section of a 3.4 m high and 15 m long avalanche-defence supporting structure located on a mountain in western Norway are presented. The site has a deep snow cover and an average ... -
Comparison of snow pressure measurements and theoretical predictions
(Journal article, 1984)Measurements of snow creep pressures from the centre section of a 3.4 m high and 15 m long avalanche-defence supporting structure located on a mountain in western Norway are presented. The site has a deep snow cover and ... -
Comparison of the condition of steel fiber-reinforced shotcrete with water-glass and alkali-free activators after more than 20 years of service in a subsea road tunnel
(Journal article, 2022-04-18)The in-service condition of steel fiber-reinforced shotcrete installed more than 20 years ago as single-shell rock support lining in the Nordkapp subsea road tunnel was investigated. The novelty of this study is the ... -
Computational models for dense snow avalanche motion
(NGI-rapport;581250-03, Research report, 1996-04-30)Seventeen various models of dense snow avalanche motion are presented. These include statistical, comparative and energy considering models for runout distance computations as well as dynamic models for avalanche motion ... -
Conceptual model for quantification of snow avalanche return periods
(NGI-rapport;20091808-01-TN, Research report, 2012-12-11)This note is a contribution to the InfraRisk project (Module B) where one of the aims is to suggest an improved standard for hazard mapping. In particular, it is attempted to overcome the deficieney pointed out for *WP Bl ... -
Conclusions from a recent survey of avalanche computational models
(NGI Publication;203, Chapter, 1998)In this paper we summarise a survey report on computational models for snow avalanche motion that was developed within the frame-work of the EU research project SAME (Snow Avalanche Modelling, Mapping and Warning in Europe). ... -
Conclusions on the current status on avalanche modelling
(Chapter, 1999)An examination of existing models shows that: (1) there is not - and probably never will be - a single model that adequately describes all avalanche types; (2) in order to account for the extraordinary variability of ... -
Considerations for using critical state soil mechanics based constitutive models for capturing static liquefaction failure of tailings dams
(Peer reviewed; Journal article, 2024) -
Considerations on scaling behavior in avalanche flow along cycloidal and parabolic tracks
(Peer reviewed; Journal article, 2018)A simple scaling analysis using a simple mass block model supports observations and measurements on snow avalanches, that the maximum front-velocity of “major” avalanches scales with the total drop height of the track. ... -
Considerations on scaling behavior in avalanche flow: Implementation in a simple mass block model
(Peer reviewed; Journal article, 2020)Observations of runout distances combined with velocity measurements suggest that “major” dry-mixed avalanches show a scale invariance to the total drop height HSC. This is in accordance to the proposed upper-limit envelope ... -
Consolidation of requirements - Analysis of questionnaire
(NGI Rapport;20190309-02-R, Report, 2022-11-08)This report presents a synthesis of the results of a questionnaire distributed to personnel from the Norwegian Public Roads Administration (NPRA) and several county road administrations. The aim of the survey was to evaluate ... -
Consolidation-induced improvements in plate anchor capacity

Constraints on Entrainment and Deposition Models in Avalanche Simulations from High-Resolution Radar Data
(Peer reviewed; Journal article, 2019)Depth-integrated simulations of snow avalanches have become a central part of risk analysis and mitigation. However, the common practice of applying different model parameters to mimic different avalanches is unsatisfying. ... -
Container experiments yearly report 2022
(NGI-rapport;20200436-10-R, Research report, 2023-07-07)Container experiments investigating leaching from alum shale under different conditions were started autumn 2020 as a part of the Under Oslo project at NGI (SP13). Furthermore, leaching from alum shale mixed with different ... -
Contamination of 8.2 ka cold climate records by the Storegga tsunami in the Nordic Seas
(Peer reviewed; Journal article, 2024)The 8200-year BP cooling event is reconstructed in part from sediments in the Norwegian and North Seas. Here we show that these sediments have been reworked by the Storegga tsunami – dated to the coldest decades of the 8.2 ... -
A contribution to the prediction of slush avalanches
(Chapter, 1985)Slush avalanches, primarily known from uninhabited arctic and mountainous regions, every year cause damage to man and property in Norway. Seeking objective criteria to identify their hazard zones, and methods for their ... -
Convective Acceleration in Porous Media: An Analogy to Pipe Flow Equations

Correction factors for undrained LE analyses of sensitive clays
(Chapter, 2017)Reliable prediction of landslide triggering threshold and landslide run-out distance is essential for hazard risk assessment. The paper focuses on studying slides in sensitive clays, which represent a major geohazard in ... -
Correlations between shear wave velocity and geotechnical parameters in Norwegian clays
(Chapter, 2016)The purpose of this paper is to present guidelines and correlations to assists geotechnical engineers in estimating Vs profiles in Norwegian clays in the absence of site-specific data. For this, a database of in situ Vs ... -
Cost and carbon implications of different foundation solutions - Desk study of foundation design for a bridge and a building in Norway
(Chapter, 2023)The choice of method and materials for pile foundations in Norway often builds on the experience of the involved parties and a preference of solutions with fewer, high-capacity piles compared to more, low-capacity piles. ...
