Norsk-islandsk samarbeid om snøskred
(Journal article, 1996)Bade Norge og Island har boligområder som er svært skredutsatt om vinteren. Noen ganger får skredene katastrofale følger. I januar 1995 gikk det et stort snøskred pa tettstedet Sudavik på Island. 15 mennesker omkom. I ... -

The Norwegian avalanche test site - Ryggfonn
(Journal article, 2007)In 1981, NGI established the full scale avalanche test site at Ryggfonn. Since then the site has been fitted with an increasing number of sensors and instruments. -
Norwegian demands on avalanche safety - legislation, quality policy and judicial practice
(Lecture, 1991)The Building and Planning Act and the Working Environment Act both have demands concerning avalanche safety. The legal demands concerning avalanche safety were first established in the Building Act of 1924. The act was put ... -
Not extinct yet: innovations in frequency domain HEM triggered by sea ice studies
(Journal article, 2015)The last 15 years have brought major innovations in helicopter towed time domain electromagnetics (EM), while few further developments have been made within the classic frequency domain segment. Operational use of frequency ... -
Notes on the Fluidization of Snow Avalanches by Air Expulsion from the Snow Cover
(NGI-rapport;20140053-03-TN, Research report, 2017-02-03)A recently proposed mechanism for fluidization of the front of dry-snow avalanches, based on air escaping from the snow cover that is compressed under the weight of the avalanche (Issler, 2013) is discussed. -
Numerical hydrogeological modelling of drainage to an excavation
(NGI-rapport;20170774-D3.3, Research report, 2021-12)The report regards the conceptual and numerical modelling of drainage scenarios to a planned excavation in a deep clay deposit in Oslo, Norway. The modelling was performed in SEEP/W 2D. Ground investigations indicate that ... -

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 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, ... -
