Ultimate Limit States of Foundation on Random Unsaturated Soils
(Chapter, 2019)This paper investigates stochastically the case of a shallow foundation resting on unsaturated heterogeneous soil under rainfall infiltration. Porosity is assumed to vary spatially while other soil parameters are constant. ... -
Undersøkelser av kjemisk utlekking og biota på testfelt på sjøbunnen i Grenlandsfjordene 2018-2019
(NIVA-rapport, Research report, 2019)Denne rapporten beskriver overvåking av spredning og biotilgjengelighet av dioksiner (PCDD/F), heksaklorbenzen (HCB) og oktaklorstyren (OCS) i de ni årene fra etablering av testfelt for tynnsjikt-tildekking i Grenlandsfjordene ... -
Use of a Pre-Drilled Hole for Implementing Thermal Needle Probe Method for Soils and Rocks
(Journal article, 2016)The thermal needle probe method, which is widely used for measuring the thermal conductivity λ of soils, deploys a long and thin metallic probe that houses a line heater and a temperature sensor. However, inserting such ... -
Use of Multi-Criteria Involvement Processes to Enhance Transparency and Stakeholder Participation at Bergen Harbour, Norway
(Peer reviewed; Journal article, 2011)Use of participatory stakeholder engagement processes could be important to reduce the risk of potential conflicts in managing contaminated sites. Most stakeholder engagement techniques are qualitative in nature and require ... -
Use of the free fall cone penetrometer (FF-CPTU) in offshore landslide hazard assessment
(Chapter, 2018)Free fall penetrometer (FF-CPTU) testing can provide significant advantages over conventional CPTU investigation for shallow sub-surface offshore site investigations. Much work has been done on soil characterisation and ... -
Using eCognition to automatically detect and map avalanche deposits from the spring 2009 avalanche cycle in the Tatra Mts., Slovakia
(Journal article, 2015)Here we present results from ongoing work where we apply an object oriented mapping algorithm developed in eCognition in order to automatically identify and digitally map avalanche deposits. The algorithm performance is ... -
Using geophysics on a terminal moraine damming a glacial lake: the Flatbre debris flow case,Western Norway
(Journal article, 2008)A debris flow occurred on 8 May 2004, in Fjǽrland, Western Norway, due to a Glacial Lake Outburst Flood and a natural terminal moraine failure. The site was investigated in 2004 and 2005, using pre- and post-flow aerial ... -
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 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 ... -
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 ...
