Discovery of Holocene ooid shoals in a siliciclastic delta, De Grey River, North West Shelf, Australia
(Peer reviewed; Journal article, 2023)Onshore and offshore site investigations along the dryland tide-dominated De Grey River delta (northwestern Australia) led to the unexpected discovery of the largest yet-known marine ooid shoals in the Indo-Pacific region. ... -
Discussion: Undrained cylindrical cavity expansion in anisotropic critical state soils
(Journal article; Peer reviewed, 2018) -
Dispersion of tsunamis: does it really matter?
(Journal article, 2013)This article focuses on the effect of dispersion in the field of tsunami modeling. Frequency dispersion in the linear long-wave limit is first briefly discussed from a theoretical point of view. A single parameter, denoted ... -
Distribution of PAHs, PCBs, and PCDD/Fs in products from full-scale relevant pyrolysis of diverse contaminated organic waste
(Peer reviewed; Journal article, 2023)Biomass pyrolysis is the anoxic thermal conversion of biomass into a carbon rich, porous solid, often called biochar. This could be a better waste management alternative for contaminated organic wastes than incineration, ... -
The diversities of large slushflows illustrated by selected cases.
(The International Snow Science Workshop (ISSW) Proceedings;, Chapter, 2010)Rapid mass movement of water-saturated snow, usually known as slushflow or slush avalanche, is a major natural hazard in Norway. The destructive forces are larger than those observed from other snow related mass flows of ... -
Drainage conditions around monopiles in sand
(Journal article; Peer reviewed, 2019)Large diameter monopiles are typical foundation solutions for offshore wind turbines. In design of the monopile foundations in sand, it is necessary to understand the drainage conditions of the foundation soil under the ... -
Drifting snow in complex terrain. Comparison of measured snow distribution and simulated wind field.
(Chapter, 2000)Snowdrift in complex terrain can cause significant problems for maintenance of road and railway systems during winter and is a major factor for snow avalanche releases. The location of accumulation and erosion areas is ... -
Drilling 1100-km-long seafloor ridges reveals how palaeoshorelines control carbonate shelf morphologies (North West Shelf, Australia)
(Peer reviewed; Journal article, 2023)The Rowley Shelf, the southern half of the tropical, carbonate-dominated, North West Shelf of Australia, is covered with linear ridges that can be tracked parallel to the coast over 1100 km between the modern coast and the ... -
DUE avalRS: Remote-Sensing Derived Avalanche Inventory Data for Decision Support and Hind-Cast after Avalanche Events
(Chapter, 2010)Each year, snow avalanches hit populated areas and parts of the transport network in the Norwegian mountain regions, leading to loss of lives and the damaging of buildings and infrastructure. We present the results of a ... -
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 ... -
Dynamic response of a steel catenary riser at touch-down zone

Dynamical Aspects of the 2017 Rigopiano Avalanch
(NGI-rapport;20170131-08-TN, Research report, 2019-01-21)Abstract: Data on the disastrous snow avalanche that occurred on 2017-01-18 at the spa hotel Rigopiano, municipality of Farindola in the Abruzzo region of central Italy, are analyzed in the present Technical Note in different ... -
Dynamical Consistency Constraints on Entrainment and Deposition in Depth-Averaged Models of Snow Avalanches and Other Gravity Mass Flows
(NGI-rapport;20110112-00-1-TN, Research report, 2012-05-18)This paper discusses several issues related to the mathematical and physical formulation of entrainment in depth-averaged models of gravity mass flows (GMF) such as snow avalanches and landslides. (i) The relation between ... -
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 ... -
Dynamics of two-layer slushflows
(NGI Publication;203, Chapter, 1998)A new mathematical model of slushflow dynamics is developed. A slushflow is treated as a two-layer flow. The lower layer consists of pure liquid phase (water) and the upper layer is a floating water saturated snow (slush). ... -
Dynamique et modélisation des avalanches
(Chapter, 2010)This chapter summarizes observations and experimental findings on the dynamics of snow avalanches that are important to understand when developing or applying numerical models for the calculation of runout distances, ... -
Dynamiske regnemodeller for steinskred
(NGI-rapport;58500-03, Research report, 1988-09-26)NGI har en nasjonal forpliktelse til å drive forskning og rådgivningsarbeid innenfor fagfeltet skred. Aktuelle skredtyper er kvikkleireskred, andre løsmasseskred, snøskred og steinskred. Dette forskningsprosjektet berører ... -
Dødsulykker i snøskred 2003-2013
(NGI-rapport;20140053-02-R, Research report, 2016-09-02)Denne NGI-rapporten inneholder analyser av dødsulykker i snøskred i Norge i 10-årsperioden 2003-2013. Rapporten er utarbeidet innen prosjekt SP 4 FoU Snøskred 2014-2016.
