Evaluation of factors affecting stakeholder risk perception of contaminated sediment disposal in Oslo harbour
(Peer reviewed; Journal article, 2011)The management of environmental pollution has changed considerably since the growth of environmental awareness in the late 1960s. The general increased environmental concern and involvement of stakeholders in today's ... -
Evaluation of reservoir and cap-rock integrity for the Longyearbyen CO2 storage pilot based on laboratory experiments and injection tests
(Journal article, 2014)Mechanical laboratory testing and interpretation of injection tests of the Longyearbyen CO2 storage pilot are used to evaluate geomechanical conditions for safe CO2 storage. The laboratory testing program includes compressive ... -
Evaluation of sample disturbance of three Norwegian clays
(Chapter, 2017) -
Evaluation of sample quality from different sampling methods in Finnish soft sensitive clays
(Peer reviewed; Journal article, 2018)The determination of reliable geotechnical parameters from laboratory testing is highly dependent on sample quality. Over the past decades, undisturbed sampling of soft sensitive clays has been performed using various ... -
Evaluation of soil models for improved design of offshore wind turbine foundations in dense sand
(Peer reviewed; Journal article, 2020)In order to perform optimised and safe design of foundations for offshore wind turbines (OWT), it is important to have calculation tools that describe the key features of water-saturated soil subjected to complex and ... -
Evolution of Mass Movements near Epicentre of Wenchuan Earthquake, the First Eight Years
(Journal article, 2016) -
Experiences from site-specific landslide early warning systems
(Journal article, 2013)Landslide early warning systems (EWSs) have to be implemented in areas with large risk for populations or infrastructures when classical structural remediation measures cannot be set up. This paper aims to gather experiences ... -
Experimental and analytical assessment of Draupne shale seal integrity for CO2 storage sites
(Lecture, 2019)Carbon dioxide (CO2) capture and storage is one of the most important measures to reduce the atmospheric concentration of CO2. To ensure safe storage, operations must be conducted in way that respects operational limitations. ... -
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 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, ... -
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 ... -
