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 ... -
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 ... -
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 ... -
V–H–M seismic capacity envelopes of strip foundations on slopes for capacity design of structure-foundation system
(Journal article; Peer reviewed, 2019)The columns and the supporting foundations are invariably subjected to the interacting axial force, V, shear force, H and moment, M. It is quite common to consider the interaction of these forces in design of structural ... -
Waste timber pyrolysis in a medium-scale unit: Emission budgets and biochar quality
(Peer reviewed; Journal article, 2020)Pyrolysis of organic waste or woody materials yields a stable carbonaceous product that can be mixed into soil and is often termed “biochar”. During pyrolysis carbon-containing gases are emitted, mainly volatile organic ... -
Wetting-Drying Response of an Unsaturated Pyroclastic Soil Vegetated with Long-Root Grass
(Peer reviewed; Journal article, 2020)This paper investigates the effect of a long-root grass on the hydraulic response of a partially saturated pyroclastic soil. The work is based on both long-term monitoring under atmospheric conditions and short-term ... -
Wetting-induced collapse behaviour of a natural and vegetated coarse pyroclastic soil
(Peer reviewed; Journal article, 2020)Unsaturated pyroclastic soils originated by Vesuvius volcano show a collapsible behaviour upon wetting with a significant reduction in volume and rearrangement of solid skeleton. The paper investigates the role played by ... -
Øysand research site: Geotechnical characterisation of deltaic sandy-silty soils
(Journal article; Peer reviewed, 2019)This paper describes the geology and geotechnical engineering properties of the fluvial and deltaic gravelly-sandy-silty sediments at Øysand, Norway. Geophysical and geotechnical site investigations carried out between ... -
Øysand research site: Geotechnical characterisation of deltaic sandy-silty soils
(NGI-rapport;20190154-09-R, Report, 2019-12-04)This paper describes the geology and geotechnical engineering properties of the fluvial and deltaic gravelly-sandy-silty sediments at Øysand, Norway. Geophysical and geotechnical site investigations carried out between ...
