Can big data and random forests improve avalanche runout estimation compared to simple linear regression?
(Peer reviewed; Journal article, 2023)Accurate prediction of snow avalanche runout-distances in a deterministic sense remains a challenge due to the complexity of all the physical properties involved. Therefore, in many locations including Norway, it has been ... -
Can high-resolution marine geophysical data be inverted for soil properties?
(Journal article, 2015) -
Can polyethylene passive samplers predict polychlorinated biphenyls (PCBs) uptake by earthworms and turnips in a biochar amended soil?
(Peer reviewed; Journal article, 2019)A pot experiment was carried out in which aged polychlorinated biphenyls (PCBs) contaminated soil was amended with biochar, and three phases; earthworms, turnips and polyethylene (PE) passive samplers, were added simultaneously ... -
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 ... -
Can we learn more from the data underlying the statistical a-ß model with respect to the dynamical behavior of avalanches?
(Journal article, 2010)Hazard and risk assessment in avalanche-prone areas involves estimation of runout distances of potential avalanches. Methods for determination of the runout may be divided into two categories: 1) methods based on statistical ... -
Caprock characterization of Upper Jurassic organic-rich shales using acoustic properties, Norwegian Continental Shelf
(Peer reviewed; Journal article, 2020)Our analysis of a comprehensive well log database and complementary mineralogical and geochemical information indicates that the risk for Upper Jurassic shales on the Norwegian Continental Shelf (NCS) to permit severe ... -

Capturing the coupled hydro-mechanical processes occurring during CO2 injection – example from In Salah
(Journal article, 2014)At In Salah, CO2 is removed from the production stream of several natural gas fields and re-injected into a deep and relatively thin saline formation, in three different locations. The observed deformation on the surface ... -

Cation exchange capacity of biochar: An urgent method modification
(Peer reviewed; Journal article, 2018)Biochar, produced through pyrolysis of organic matter, is negatively charged, thus contributing to electrostatic adsorption of cations. However, due to its porous structure and contents of alkaline ashes, the determination ... -
CCS Leakage Detection Technology - Industry Needs, Government Regulations, and Sensor Performance
(Peer reviewed; Journal article, 2017)Reliable CCS monitoring is vital in order to confirm that injected CO2 stays in the reservoir as intended, and that any occurring leakage is promptly detected allowing corrective actions to be initiated. Motivations for ... -
Cements for tunnel grouting – Rheology and flow properties tested at different temperatures
(Peer reviewed; Journal article, 2019)This paper presents work being carried out in Work Package 3 of TIGHT (True Improvement in Grouting High pressure Technology for tunnelling) project. The objective is to investigate flow and mechanical properties of three ... -
Centrifuge study of p-y curves for vertical-horizontal static loading of piles in sand
(Peer reviewed; Journal article, 2020)Pile foundations for offshore structures are subjected to vertical-horizontal load combinations. The current design method separately analyzes horizontal and vertical responses of piles without considerations of the combined ... -
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. ... -
Challenging Infrastructure Project Assisted by Monitoring and Numerical Modelling as the Follo Line Tunnels were Excavated Below Existing Tunnels

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 sand-steel interface shearing behaviour for the interpretation of driven pile behaviour in sands
(Peer reviewed; Journal article, 2019)The installation and loading of steel piles driven in sands modifies both the piles' surface topography and the characteristics of the granular materials present adjacent to the pile shaft. Large-displacement ring shear ... -
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 ...
