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

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: • ... -
Verktøy for Risikohåndtering – Manual Norsk
(NGI-rapport;20170774-D5.2, Research report, 2019-09-08)Hensikten med verktøyet er å systematisk identifisere og vurdere risiko for uønskede hendelser. Risikomatrisen som genereres kan danne grunnlag for valg av anleggsmetoder og behov for avbøtende tiltak. Risikovurderingen ... -
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 ... -
Vibration induced damage due to construction work – Blasting tests
(NGI-rapport;20170774-D4.2, Research report, 2021-12-01)In this study, two instrumented blast test series were performed in a rock quarry in Norway. For the first test series, two buildings were erected, one made of Light Expanded Clay Aggregate (Leca) blocks, and one in ... -
Vibration induced damage due to construction work – Effect of vibrations on slope stability
(NGI-rapport;20170774-D4.3, Research report, 2019-08-29)A landslide-triggered tsunami caused extensive material damage at Statland, Norway in 2014. Other landslides in Sweden and US have also been triggered by man-made vibrations. To understand better how vibrations from vibratory ... -
Vulnerability of houses and persons under avalanche impact – the avalanche at Longyearbyen on 2015-12-19
(The International Snow Science Workshop (ISSW) Proceedings;, Chapter, 2016)This study uses data from the avalanche that killed two persons and destroyed eleven essentially identical wood-frame houses in Longyearbyen, Svalbard, on 2015-12-19. The avalanche is back-calculated with a dynamical model ... -
