Comparing model and full-scale experiments on snow avalanche dynamics
(NGI-rapport;58120-28, Research report, 1992-10-01)The paper is a part of a Japanese - Norwegian collaboration on snow avalanche dynamics. The results of model experiments carried out at the Institute of Low Temperature Science, Sapporo are compared with full-scale ... -
Comparing topographical and dynamical runout models by ideas of nearest neighbour method
(Journal article, 1999)Different avalanche runout models are used to compare the calculated results against observations of 230 real avalanches in Norway. The parameters used in the models are investigated and optimized to get the best fit to ... -
Comparison of analytical and numerical design of suction anchors in deepwater clays
(Chapter, 2017)The paper presents the result of an extensive study on the undrained holding capacity of suction anchors with different length-to-diameter ratios. The clays used in this study have a linearly increasing undrained shear ... -
Comparison of avalanche front velocity measurements and implications for avalanche models
(Journal article, 2013)Besides the runout distance of an avalanche information on avalanche intensity along the path is often required for hazard zoning or planning of mitigation measures. The avalanche (front) velocity is a common intensity ... -
Comparison of avalanche front velocity measurements: Supplementary energy considerations
(Journal article, 2013)A series of front velocity measurements were re-analyzed to derive estimates on the mean retarding acceleration of dry-mixed avalanches (i.e. dry-snow avalanches, which were partially fluidized and accompanied by a powder ... -
A comparison of avalanche models with data from dry-snow avalanches at Ryggfonn, Norway
(Chapter, 2005)Twelve well-documented dry-snow avalanches from the instrurnented Ryggfonn path in western Norway were selected for back-ca1culations with several dynamical avalanche models. In each case, the run-out distance, the front ... -
Comparison of Sealing Properties of Amundsen and Drake Formations for Potential CO2 Storage in North Sea
(Chapter, 2019)Seal evaluation for CO2 storage is different from that of a hydrocarbon trap since the oil or gas accumulation itself validates the cap-rock integrity. However, in case of subsurface CO2 storage a careful investigation is ... -
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 ... -
