Experimental investigation of natural fracture stiffness and flow properties in a faulted CO2 bypass system (Utah, USA)
(Peer reviewed; Journal article, 2020)Fracture stiffness and flow properties have been measured in the laboratory using naturally fractured fault rock samples from the Little Grand Wash fault, Utah, USA. We compare fracture closure and related flow change ... -
Experimental modelling of primary migration in a layered, brittle analogue system
(Peer reviewed; Journal article, 2022) -
Experimental percolation of supercritical CO2 through a caprock
(Journal article, 2009)Leakage of CO2 into the atmosphere is the most crucial concern for geological storage of anthropogenic CO2. Leakage routes could develop through existing wells and pipelines, but also by natural migration of CO2 rich ... -
Experimental study on axial and lateral bearing capacities of nonwelded composite piles based on pile load test results
(Chapter, 2016)In the presented paper, the axial and lateral behaviors of non-welded composite piles were investigated based on pile load test results. Recently, a composite pile composed of steel pipe and PHC pile was introduced into ... -
Experimental triaxial testing of swelling gouge materials
(Peer reviewed; Journal article, 2019)Adequate rock support in weakness zones that may contain swelling minerals poses one of the main challenges of excavating tunnels in hard rock conditions. Deformations under such conditions are influenced by several factors, ... -
Experiments with remote sensing in the context of avalanche warning and detection
(Chapter, 2012)Two Norwegian projects carried out by NGI and NR have investigated and experimented with the potential of using remote sensing for avalanche warning and detection: The Norwegian Space Centre (NSC) supported project “Improved ... -
Exploring seismic detection and resolution thresholds of fault zones and gas seeps in the shallow subsurface using seismic modelling

Exploring the significance of the fluidized flow regime for avalanche hazard mapping.
(Journal article, 2008)Observational and experimental evidence suggests that it is important to explicitly account for the fluidized flow regime in avalanche hazard mapping due to its high mobility, intermediate density and high velocity. We ... -
Extreme precipitation induced landslide event on 30 July 2019 in Jølster, western Norway
(Peer reviewed; Journal article, 2022)A torrential rain event struck western Norway on Tuesday 30 July 2019. Most severely affected was the Jølster community, where numerous landslides and floods damaged public infrastructure and private property. This resulted ... -
Extreme precipitation on dry ground in western Norway – characteristics of induced landslides call for adaptation of the Norwegian practice in landuse planning
(Peer reviewed; Journal article, 2023)Following a particularly dry summer, a torrential rain event struck Western Norway on Tuesday 30 July 2019. The resulting floods and shallow landslides caused one fatality and severe damages to public and private infrastructure ... -

The eye in the sky: Avalanche mapping from space
(The International Snow Science Workshop (ISSW) Proceedings;, Chapter, 2016)The Seward Highway in Alaska has over one hundred avalanche paths spread out along a 150 km major transportation corridor, which traverses three different avalanche climatic regimes. This coupled with a small staff can ... -
Facilitating microplastic quantification through the introduction of a cellulose dissolution step prior to oxidation: Proof-of-concept and demonstration using diverse samples from the Inner Oslofjord, Norway
(Peer reviewed; Journal article, 2020)Identifying and quantifying microplastic in marine samples can be facilitated by removing natural organic matter (NOM). Cellulosic material, like chitin, however, are a type of NOM that is resistant to chemical digestion, ... -
Factual report - Halden research site
(NGI-rapport;20160154-04-R Rev. 1, Report, 2020-01-06)Halden silt site is property of Halden municipality and it is known locally as Rødsparken. As part of the characterization of Halden silt site during NGTS project, two main reports are prepared: 1) a factual report ... -
Factual Report - Permafrost Research Site
(NGI-rapport;20160154-06-R, Report, 2020-01-01)Two benchmark sites are established near Longyearbyen, Svalbard (78°13’N, 15°28’E) for long-term geotechnical testing and evaluation of field investigation methods in perennially frozen soils (i.e. permafrost). These sites, ... -
Factual report - Øysand research site
(NGI-rapport;20160154-08-R, Report, 2020-01-15)As part of the characterization of Øysand Sand site during NGTS project, two main reports are prepared: 1) a factual report (20160154-08-R) and 2) an interpretation report (20160154-09-R) (see figure in the next page). The ... -
Fading positive effect of biochar on crop yield and soil acidity during five growth seasons in an Indonesian Ultisol
(Peer reviewed; Journal article, 2018)Low fertility limits crop production on acidic soils dominating much of the humid tropics. Biochar may be used as a soil enhancer, but little consensus exists on its effect on crop yield. Here we use a controlled, replicated ... -
faSavageHutterFOAM 1.0: depth-integrated simulation of dense snow avalanches on natural terrain with OpenFOAM
(Peer reviewed; Journal article, 2018)Numerical models for dense snow avalanches have become central to hazard zone mapping and mitigation. Several commercial and free applications, which are used on a regular basis, implement such models. In this study we ... -
