Can the propagation speed of snow avalanches be determined by seismic methods?
(Chapter, 2004)The main question of the given work is whether the propagation speed of snow avalanches can be determined using seismic observations. The significance of having at least an order of magnitude estimate of this basic physical ... -
Challenges for the closure and natural rehabilitation of bauxite residue disposal sites
(Chapter, 2019)In the Bayer process, bauxite ore is digested with NaOH at high temperature and pressure, which results in the production of alumina and the recrystallisation of various residual minerals ending up in a bauxite residue. ... -
Changes in the snow drift pattern caused by a building extension. Investigations through scale modeling and numerical simulations
(Chapter, 2000)Snowdrifts around buildings can cause serious problems when formed on undesirable places. The formation of snowdrifts is highly connected to the wind pattern around the buildings, and the wind pattern is again dependent ... -
Changes of the avalanche cadastre in the Czech part of the Giant Mts.
(NGI Publication;203, Chapter, 1998)Giant Mts. are the highest and the only mountain range of the Czech Republic which features considerable avalanche activity. There are at average 22 avalanches events on 47 avalanche paths in a year. Human colonisation and ... -
Characterisation of the Halden silt
(Chapter, 2016)NGI recently established a research site on a natural silt deposit to accommodate some of the challenges related to intermediate soils. This study briefly summarises the geological history and the preliminary geotechnical ... -
Characterization of method Uncertainty for Axial Pile Design
(Chapter, 2018)The paper describes two approaches for deriving the mean, standard deviation and probability density function of the method uncertainty for an axial pile capacity calculation method. The focus of this paper is on estimating ... -
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 ... -
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 ... -
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 ... -
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 ... -
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. ... -
Could retrieval of snow layer formation by optical satellite remote sensing help avalanche forecasting? Presentation of first results
(The International Snow Science Workshop (ISSW) Proceedings;, Chapter, 2008)Of special interest within the field of avalanche research and avalanche warning are properties related to snow grain type and snow grain size at the surface. In continental and intermountain avalanche climates weak layers ... -

Cross-comparison of Selected Avalanche Observations
(Chapter, 2019)In many mountainous regions, snow avalanches are severe threats to the population and their infrastructure. Delineation of avalanche endangered areas or the design of suffcient mitigation measures require in-depth understanding ... -
CSEM for CO2 Storage – Feasibility Study at Smeaheia to Optimise Acquisition
(Chapter, 2021)In this work, we evaluate the use of controlled-source electromagnetics (CSEM) for CO2 monitoring at Smeaheia, a possible candidate for future phases of the Norwegian full-scale CCS project. CSEM is sensitive to electrically ...
