Dynamic properties of lightweight foamed glass and their effect on railway vibration
(Peer reviewed; Journal article, 2019)Deformation properties of lightweight coarse grained material from recycled foamed glass have been determined from large-scale triaxial tests on prismatic specimens with dimensions 40 cm × 40 cm × 80 cm. Deformations were ... -
Dynamically consistent entrainment laws for depth-averaged avalanche models
(Journal article; Peer reviewed, 2014)The bed entrainment rate in a gravity mass flow (GMF) is uniquely determined by the properties of the bed and the flow. In depth-averaging, however, critical information on the flow variables near the bed is lost and ... -
Earthquake Disaster Risk Reduction in Iran: Lessons and ‘‘Lessons Learned’’ from Three Large Earthquake Disasters—Tabas 1978, Rudbar 1990, and Bam 2003
(Journal article, 2015)This article addresses three large earthquake disasters in Iran: Tabas in 1978, Rudbar in 1990, and Bam in 2003. Lessons and "Lessons Learned" from these three earthquake disasters were investigated together with their ... -
Earthquake Geotechnics in Offshore Engineering
(Chapter, 2018)This paper presents a number of geotechnical issues encountered in earthquake design of offshore structures and subsea facilities. Parallel with construction of traditional structures such as jackets and gravity-based ... -
Earthquake related tsunami hazard along the western coast of Thailand
(Journal article, 2006)The primary background for the present study was a project to assist the authorities in Thailand with development of plans for how to deal with the future tsunami risk in both short and long term perspectives, in the wake ... -
Earthquake response of monopiles and caissons for Offshore Wind Turbines founded in liquefiable soil
(Peer reviewed; Journal article, 2020)Monopile has been the most widespread foundation type for Offshore Wind Turbines (OWTs) in shallow waters. Caisson (skirted) foundations have also been evaluated in some projects as an economical alternative. While the ... -
Effect of Activated Carbon Amendment on Bacterial Community Structure and Functions in a PAH Impacted Urban Soil
(Peer reviewed; Journal article, 2012) -
Effect of biochar on crust formation, penetration resistance and hydraulic properties of two coarse-textured tropical soils
(Peer reviewed; Journal article, 2017)Biochar (BC) has been reported to improve a number of soil structural and hydraulic properties but detailed studies are scant on how BC affects crust formation, penetration resistance, water repellency and saturated hydraulic ... -
Effect of brine-CO2 fracture flow on velocity and electrical resistivity of naturally fractured tight sandstones
(Peer reviewed; Journal article, 2017)Fracture networks inside geological CO2 storage reservoirs can serve as primary fluid flow conduit, particularly in low-permeability formations. While some experiments focused on the geophysical properties of brine- and ... -
Effect of cone penetrometer type on CPTU results at a soft clay test site in Norway
(Chapter, 2018)Seven different cone penetrometers from 5 manufacturers have been used in a comparative testing program at the Norwegian GeoTest site (NGTS) on soft clay in Onsøy, Norway. Tests with all cone types give very repeatable ... -
Effect of conservation farming and biochar addition on soil organic carbon quality, nitrogen mineralization, and crop productivity in a light textured Acrisol in the sub-humid tropics
(Peer reviewed; Journal article, 2020)Conservation farming (CF), involving basin tillage, residue retention and crop rotation, combined with biochar may help to mitigate negative impacts of conventional agriculture. In this study, the effects of CF on the ... -
Effect of diagenesis on pore pressures in fine-grained rocks in the Egersund Basin, Central North Sea
(Journal article, 2015)Pore pressure in fine-grained rocks is important with respect to drilling problems such as kicks, blowouts, borehole instability, stuck pipe and lost circulation. In this study, a succession of overpressured, fine-grained, ... -
Effect of foundation modelling on the fatigue lifetime of a monopile-based offshore wind turbine
(Peer reviewed; Journal article, 2017) -
Effect of foundation type and modelling on dynamic response and fatigue of offshore wind turbines
(Peer reviewed; Journal article, 2019)This paper presents dynamic response and fatigue analyses of several bottom‐mounted offshore wind turbine (OWT) models, simulated in the aero‐hydro‐servo‐elastic simulation tool FAST. The distinction between the models is ... -

Effect of kinematic interaction on seismic response of offshore wind turbines on monopiles
(Peer reviewed; Journal article, 2020)Interest in renewable energy over the past decade has motivated a remarkable research on offshore wind energy. Due to the environmental loading conditions in the early developments of offshore wind farms, the focus of the ... -
Effect of piezocone penetration rate on the classification of Norweian silt
(Chapter, 2018)Interpretation of Cone Penetration Tests (CPTU) in intermediate soils is complex due to partially drained conditions during penetration. In order to gain more insight into the material behavior of silt during a CPTU, an ... -
Effect of Shallow Slip Amplification Uncertainty on Probabilistic Tsunami Hazard Analysis in Subduction Zones: Use of Long-Term Balanced Stochastic Slip Models
(Peer reviewed; Journal article, 2019)The complexity of coseismic slip distributions influences the tsunami hazard posed by local and, to a certain extent, distant tsunami sources. Large slip concentrated in shallow patches was observed in recent tsunamigenic ... -
