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 ... -
Vær- og snøforhold samt skredsituasjoner vinterene 1974-75, 1975-76, 1976-77, 1977-78, 1978-79. Grasdalen, Stryn
(NGI-rapport;58000-03, Research report, 1985-12-27)En beskrivelse av værforholdene ved Garasdalen for vintersesongene fra desember 1974 til april 1979 er presentert i denne rapporten. En oversikt over skredaktiviteten i den samme perioden er også gitt. -
Vær-, snø- og skredobservasjoner i Grasdalen. En sammenfatning
(NGI-rapport;58110 R, Research report, 1983-09-29)Observasjonene i Grasdalen gjøres på en mest mulig standardisert måte. Metodikken for værobservasjonene er henta fra Meteorologisk Institutts "Håndbok for meteorologiske observatører 1" og "Meteorologiske koder, synop". ... -
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 ... -

Weather and snowpack conditions essential to slushflow release and downslope propagation
(The International Snow Science Workshop (ISSW) Proceedings;, Chapter, 1994)Rapid mass movement of water-saturated snow, usually known as slushflow or slush avalanche, is a major natural hazard in Norway. Slushflows occur in winter during heavy rainfall, as well as due to intense thaw in spring. ... -
Weather stations in Norway suitable for SNOWPACK modelling in Norway in 2016
(NGI-rapport;20140053-04-TN, Research report, 2017-01-23)A physical SNOWPACK model developed by Swiss Federal Institute for Snow and Avalanche Research, SLF, requires following meteorological observations as input data1 for the model simulations: - air temperature (TA) - ... -

Weight of evidence tools in the prediction of acute fish toxicity
(Peer reviewed; Journal article, 2022)Acute fish toxicity (AFT) is a key endpoint in nearly all regulatory implementations of environmental hazard assessments of chemicals globally. Although it is an early tier assay, the AFT assay is complex and uses many ... -
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
