Numerical modeling of a slushflow event
(The International Snow Science Workshop (ISSW) Proceedings;, Chapter, 2004)Slushflows—flowing mixtures of snow and water—constitute a natural hazard especially in higher latitudes, i.e., Norway, Iceland, or Alaska. The combination of high densities and high mobility can make them to a highly ... -

Numerical Modeling of an Asteroid Impact on Earth: Matching Field Observations at the Chicxulub Crater Using the Distinct Element Method (DEM)
(Peer reviewed; Journal article, 2023) -
Numerical modeling of blowing and drifting snow in Alpine terrain.
(Journal article, 2001)In mountainous regions, snow transport due to wind significantly influences snow distribution and, as a result, avalanche danger. A physically based numerical two-Iayer model is developed to simulate blowing and drifting ... -
Numerical modeling of liquefaction and its impact on anchor piles for floating offshore structures
(Peer reviewed; Journal article, 2019)Anchor piles and suction anchors have been used for anchoring different types of offshore structure in the past four decades. The recent growing interest and demand for wind energy has motivated the industry to evaluate ... -
Numerical prediction and back-calculation of time-dependent behaviour of Ballina test embankment
(Peer reviewed; Journal article, 2017)The paper describes the Class A prediction and Class C back-calculations of the Ballina test embankment using the finite element program Plaxis and the Soft Soil Creep Model (SSCM). The prediction underestimated the measured ... -
Numerical runout simulation of debris avalanches in the Faroe Islands, North Atlantic Ocean
(Journal article, 2012-08-31)The Faroe Islands in the North Atlantic Ocean are susceptible to flow-type landslides in coarse-grained highly organic colluvium. Following several hazardous debris avalanche events, research work has been initiated to ... -
Numerical simulation of impulse wave generation by idealized landslides with OpenFOAM
(Peer reviewed; Journal article, 2020)Landslide tsunamis and impulse waves are hazardous events with severe socioeconomic impacts. A long standing problem with simulations of these events is the generation stage, where landslides and water interact. Depth-averaged ... -
Numerical solutions for nonlinear high damping rubber bearing isolators: Newmark's method with Netwon-Raphson iteration revisited
(Peer reviewed; Journal article, 2018)Numerical methods for the solution of dynamical problems in engineering go back to 1950. The most famous and widely-used time stepping algorithm was developed by Newmark in 1959. In the present study, for the first time, ... -
Numerical Study of Consolidation of Slurry Tailings Considering Continuous Update of Material Properties
(Peer reviewed; Journal article, 2024) -
Numerical study on the behaviour of horizontal anchor using upgraded SANISAND-MS

Nutrient effect of various composting methods with and without biochar on soil fertility and maize growth
(Journal article; Peer reviewed, 2019)This work showed for the first time that organic nutrient transformation techniques based on locally available materials (manure, green waste and advanced biochar) can increase fertilizing efficiency of the resulting ... -

Nye boligområder ofte skredutsatt: Fareområder må registreres før planer fastlegges
(Journal article, 1981)I mange av våre bratte fjellsider, særlig på Vestlandet og i Nord-Norge er skred en reell fare. Ny bebyggelse blir ofte plassert i mer skredutsatte strøk. Dette ble bl.a. konstatert skredvinteren 1978/79. Bygningsloven ... -
Objective comparison of two to three dimensional avalanche model output and field data using the AIMEC approach
(The International Snow Science Workshop (ISSW) Proceedings;, Chapter, 2012)In recent years two to three dimensional avalanche simulation tools have gained importance to estimate the hazard. The models are optimized to determine run out distances of avalanches. However, technically dynamic models ... -
Observations of preferential summer melt of Arctic sea-ice ridge keels from repeated multibeam sonar surveys
(Peer reviewed; Journal article, 2023)Sea-ice ridges constitute a large fraction of the total Arctic sea-ice area (up to 40 %–50 %); nevertheless, they are the least studied part of the ice pack. Here we investigate sea-ice melt rates using rare, repeated ...
