Using local monitoring data for regional forecasting of weather-induced landslides in Norway
(Chapter, 2019)Since 2013, a national early warning system addressing weather-induced landslides in soils is operational in Norway. The system is based on real-time hydro-meteorological measurements used as input to a spatially distributed ... -
Using of GIS technology for avalanche hazard mapping, scale 1:10 000
(NGI Publication;203, Chapter, 1998)The sites with the size of 50·50 m2 having a various probability of avalanche formation were revealed for a given territory covering an area of 3·4 km2. Crossclassification of sites considering their slopes and snow cover ... -
Using Passive Samplers to Track per and Polyfluoroalkyl Substances (PFAS) Emissions From the Paper Industry: Laboratory Calibration and Field Verification
(Peer reviewed; Journal article, 2021)Per and polyfluoroalkyl substances (PFAS) are becoming more stringently regulated and as such, a more diverse suite of environmental monitoring methods is needed. In this work a polar organic chemical integrative sampler ... -
Using REACH registration data to rank the environmental emission potential of persistent and mobile organic chemicals
(Journal article; Peer reviewed, 2018)Organic chemicals that are persistent and mobile in the aquatic environment exhibit a hazard to contaminate drinking water resources. In this study an emission score model was developed to rank the potential of substances ... -
Utfordringer med svarte leirskifere; mellomlagring og naturlige blandmasser
(Chapter, 2022)Det er planlagt flere store byggeprosjekt i Oslo-regionen de neste årene. Dette vil resultere i utgraving av potensielt syredannende svart leirskifer i volumer som er større enn kapasiteten til godkjente deponier. NGI har ... -
Utviklingstrekk og muligheter for sikring av veger mot snøskred
(Journal article, 1984)Snøutvalget i Statens Vegvesen var i virksomhet i perioden 1974- 82. Hovedformålet til utvalget var å følge med i snøprosjekter ved NTH, initiere forsøk med sikring av veger mot. snøskred og drivsnø, og sørge for at ... -

Validation of a ground-based telescope-assisted hyperspectral remote sensor for soil measurements
(Peer reviewed; Journal article, 2020)The utility of the ground-based soil observation laser absorption spectrometer (SOLAS) was demonstrated through spectral reflectance measurements of five soil types during laboratory- and field-based collection. The SOLAS ... -
Validation of earthquake analysis methodology of a suction-caisson foundation-structure through model testing
(Peer reviewed; Journal article, 2023) -
Validity of the NTNU Prediction Model for D&B Tunnelling
(Peer reviewed; Journal article, 2023) -
Vane Shear Strength in Terms of Effective Stresses
(NGI Publication;209, Chapter, 2022)Experience with the shear strength determined with the field vane has shown that the measured values of the strength, normalized with the effective overburden stress, suv/σ'vo, are often lower than 0.1 for normally ... -
Variability in the three-dimensional geometry of segmented normal fault surfaces
(Peer reviewed; Journal article, 2021)Normal faults are often complex three-dimensional structures comprising multiple sub-parallel segments separated by intact or breached relay zones. Relay zones are classified according to whether they step in the strike ... -
Variable rate of penetration and dissipation test results in a natural silty soil
(Chapter, 2018)Variable rate of penetration over 1.2 to 1.5 m intervals were carried out in a natural clayey silt followed by dissipation tests. The tests are grouped into two main sets: an upper set from 5 to 6.5 m and a deeper set from ... -
Velocity anisotropy of upper jurassic organic-rich shales, Norwegian continental shelf
(Peer reviewed; Journal article, 2017)This study investigates the seismic velocity anisotropy of two organic-rich shales from the Norwegian Continental Shelf. The tested organic-rich shale samples were from the Upper Jurassic Draupne and Hekkingen formations ... -
Verdens vakreste – og farligste? – fjord
(Journal article, 2015)Spillefilmen Bølgen av Roar Uthaug er blitt en gedigen kinosuksess. Den er solgt til over 100 land og valgt som Norges Oscar-bidrag 2016. Handlingen tar utgangspunkt i et tenkt scenario, der et stort skred fra fjellet ... -
Verification of a framework for cyclic p-y curves in clay by hindcast of Sabine River, SOLCYP and centrifuge laterally loaded pile tests
(Peer reviewed; Journal article, 2020)Pile foundations supporting offshore structures, such as jacket platforms, are subjected to cyclic lateral loading. The capacity and deformation of these pile foundations under cyclic lateral loading are important and ... -
Verification of avalanche bulletins by questionnaires
(NGI Publication;203, Chapter, 1998)The paper describes how avalanche bulletins (regional and national) are being verified by means of questionnaires in Switzerland. At the beginning of winter 1996/97 a set of four questionnaires has been introduced: • ... -
Vertical and lateral transport of biochar in light-textured tropical soils
(Peer reviewed; Journal article, 2016)Field experiments were conducted in Arenosols (loamy fine sand) and Acrisols (sandy loam) in Zambia to quantify vertical and lateral transport of biochar (BC) using the BC and soil 13C isotope signatures and total organic ... -
Vertical profiles of sedimentary polycyclic aromatic hydrocarbons and black carbon in the Gulf of Gdańsk (Poland) and Oslofjord/Drammensfjord (Norway), and their relation to regional energy transitions
(Peer reviewed; Journal article, 2018)The analysis of undisturbed sediment cores is a powerful tool for understanding spatial and temporal impacts of anthropogenic emissions from the energy and transport sectors at a regional scale. The spatial and vertical ... -
Vertically integrated models for coupled two-phase flow and geomechanics in porous media
(Peer reviewed; Journal article, 2016)Models of reduced dimensionality have been found to be particularly attractive in simulating the fate of injected CO2 in supercritical state in the context of carbon capture and storage. This is motivated by the confluence ...
