Effects of rotational submarine slump dynamics on tsunami-genesis – new insight from idealized models and the 1929 Grand Banks event
(Peer reviewed; Journal article, 2020)Sediment slumps are known to have generated important tsunamis such as the 1998 Papua New Guinea (PNG) and the 1929 Grand Banks events. Tsunami modellers commonly use solid blocks with short run-out distances to simulate ... -
Effects of stress reduction on geomechanical and acoustic relationship of overconsolidated sands
(Peer reviewed; Journal article, 2019)Relationship between different geomechanical and acoustic properties measured from seven laboratory tested unconsolidated natural sands with different mineralogical compositions and textures were presented. The samples ... -
Electrochemical Oxidation for Treatment of PFAS in Contaminated Water and Fractionated Foam─A Pilot-Scale Study
(Peer reviewed; Journal article, 2023) -
Emerging insights into the dynamics of submarine debris flows
(Journal article, 2005)Recent experimental and theoretical work on the dynamics of submarine debris flows is summarized. Hydroplaning was first discovered in laboratory flows and later shown to likely occur in natural debris flows as well. It ... -
Empirical approach based on centrifuge testing for cyclic deformations of laterally loaded piles in sand
(Journal article; Peer reviewed, 2018)A systematic study into the response of monopiles to lateral cyclic loading in medium dense and dense sand was performed in beam and drum centrifuge tests. The centrifuge tests were carried out at different cyclic load and ... -
Empirical Calculations of Snow–Avalanche Run–out Distance Based on Topographic Parameters
(Journal article, 1980)A method for calculation of “maximum” avalanche run–out distance based on topographic parameters only is described. 423 well–known avalanches have had their maximum extent registered. The average gradient of avalanche path ... -
Engineering properties of low to medium overconsolidation ratio offshore clays
(Peer reviewed; Journal article, 2019)This paper presents a summary of the geotechnical engineering properties of low to medium overconsolidation ratio offshore inorganic clays derived from a high quality database. These properties, such as preconsolidation ... -
Engineering properties of Norwegian peat for calculation of settlements
(Peer reviewed; Journal article, 2022) -
Environmental impact assessments of geotechnical works
(NGI-rapport;20200436-12-R, Research report, 2023-08-14)One of the major contributors to global carbon emissions is the construction sector. Using world environmental input-output tables from 2009, the total CO2-emissions from the global construction sector was calculated to ... -
Estimates on the reach of the powder part of avalanches
(Lecture, 2018)Avalanche observations from Norway, Austria and Switzerland, which distinguish between dense (fluidized) flow and powder part, are analyzed to obtain probability information about the reach of the powder part. The analysis ... -
Estimating Avalanche Triggering Probability using meteorological and local terrain parameters through a fuzzy inference approach
(NGI-rapport;20170131-12-TN, Research report, 2019-04-23)The aim of the present study is the quantitative estimation of snow avalanche triggering probability (ATP) for daily local forecasting purposes based on meteorological and local terrain factors. At present, ATP is indirectly ... -
Estimating exhumation using experimental compaction trends and rock physics relations, with continuation into analysis of source and reservoir rocks: Central North Sea, offshore Norway
(Peer reviewed; Journal article, 2017)We present a quantitative estimate of exhumation in the Central North Sea by examining depth trends of velocity and density data compared to experimental compaction trends. Additionally, seismic inversion and attribute ... -
Estimating run-out distances for extreme snow avalanches
(Lecture, 1992)Lecture presented at the Universitè Européenne d'Eté. Neige et Avalanches, Chamonix 1992. Estimating the run-out distances for snow avalanches is an important task for land use planning in mountaneous areas. The practical ... -
Estimation of hysteretic soil damping from laboratory measurements including strain accumulation
(NGI Rapport;20110087-01-R, Research report, 2014-05-12)The periodic forces due to wind, surface waves and swells on offshore installations such as offshore wind turbines lead to cyclic motion of the soil foundation. The damping properties of soils account for a part of the ... -
Estimation of natural frequencies and damping using dynamic field data from an offshore wind turbine
(Peer reviewed; Journal article, 2020)The dynamic characteristics of offshore wind turbines are heavily affected by environmental loads from wave and wind action and nonlinear soil behaviour. In the design of the monopile structures, the fatigue load due to ... -
Estimation of preconsolidation stress of clays from piezocone by means of high-quality calibration data
