Avalanche probability: Slab release and the effect of forest cover
(Lecture, 2018)One of the main challenges in regard to hazard mapping is to estimate avalanche probabilities and avalanche size for a given path. One reason for this is the lack of sufficient data. By definition, avalanches of interest ... -
Avalanche rescue and mission risk in Norway 1996-2010
(The International Snow Science Workshop (ISSW) Proceedings;, Chapter, 2013)Well documented data from Norwegian avalanche rescue missions are evaluated according to risk assessment. Data have been collected from police records and logs from joint rescue coordination centres. Mission risk assessments ... -
Avalanche risk along a 420 kV transmission line in Iceland
(Chapter, 2008)Two transmission lines between Flj6tsdalur and Reyöarfjöröur in northeast Iceland have been investigated conceming snow avalanche hazard. As a basis for the calculations of the return periods of the avalanches, weather and ... -
Avalanche risk along a 420 kv transmission line in Iceland.
(The International Snow Science Workshop (ISSW) Proceedings;, Chapter, 2006)Two transmission lines between Fljótsdalur and Reyðarfjörður in northeast Iceland have been investigated concerning snow avalanche hazard. Given a specific level of probability of failure for both the lines less than ... -
Avalanche run-out on counter-slopes
(Journal article, 2003)Counter-slopes in avalanche paths influence avalanche flow in similarways as defence structures. Measurements and calculations of run-outon such slopes will improve our understanding of retaining damdesign. We have studied ... -
The avalanche situation in a special winter. Review of the 09/10 season in Norway.
(The International Snow Science Workshop (ISSW) Proceedings;, Chapter, 2010)The 2009/10 season featured significantly different snow conditions compared to the usually maritime snow pack in most of Norway. A stable high-pressure system over large parts of Europe led to low temperatures and limited ... -
The avalanche situation in Neskaupstadur, Iceland : A preliminary defensive plan
(NGI Publication;203, Chapter, 1998)The avalanche situation in the town of Neskaupstaôur is rather unique and in many respects more difficult than in any other place in Iceland. The avalanche risk is high in a large portion of the 2,7 km long residential ... -
Avalanches in Longyearbyen Svalbard 2015 and 2017: Avalanche Protection - Visions
(Journal article, 2017)Longyearbyen, the administrative centre of the Svalbard archipelago, is facing most types of natural hazards under a changing Arctic climate. The first indication in meteorological data of a change in climate was a heavy ... -
Avalanches in the context of climate change in the northern regions: Avalanche Protection - Visions
(Journal article, 2017)Avalanches have caused more than 1500 deaths the past 150 years in Norway. Development in rural areas make us more vulnerable to geohazards. Climatic warming with increased frequency and strength of extreme weather events ... -
AVO Modelling Considering Various Caprock and Reservoir Scenarios for Potential CO2 Storage in Smeaheie Area, Northern North Sea
(Chapter, 2019)We have performed a comparative study of undrained triaxial testing with five different laboratories, to explore the reproducibility of test results. Opalinus Clay was sourced as testing material from a borehole at the ... -

Back-Calculation of Element Tests with a Rate Dependent Soft Soil Model
(Chapter, 2016)It is well known that soft clays are geo-materials with properties such as fabric, bonding and rate-dependency. The response observed when modelling complex boundary value problems will depend on the ability of the soil ... -
Back-calculation of pillar foundation for Skjeggestad Bridge
(Peer reviewed; Journal article, 2021)In 2015, a landslide incapacitated the expressway E18 in southern Norway because one of the large foundation pillars of the southern lane of Skjeggestad Bridge near Mofjellbekken failed. This accident immobilised throughway ... -
Back-calculations of observed avalanches against natural deflecting dams
(The International Snow Science Workshop (ISSW) Proceedings;, Chapter, 2012)The objective of this study is to assess the reliability of presently available numerical avalanche models in predicting avalanche flow about deflecting natural terrain features such as large boulders or moraine ridges. ... -
Basal shear and normal stresses of dry and wet snow avalanches after a slope deviation
(Journal article, 2007)Basal shear and normal force measurements of dry and wet snow avalanches and slush flows from the Weissfluhjoch snow chute are presented. This chute contains two slope angle transitions in order to measure the effect of ... -
Bayesian rock-physics inversion: Application to CO2 storage monitoring

Behavior and Critical Failure Modes of Strip Foundations on Slopes under Seismic and Structural Loading
(Peer reviewed; Journal article, 2019)This paper presents a numerical study on capacity envelopes of strip foundations placed on the top and the face of two typical soil slopes at different offset distances and subjected to earthquake effects using the ... -
Behavior of slopes under multiple adjacent footings and buildings
(Peer reviewed; Journal article, 2018)This article examines the response of soil slopes under adjacent embedded strip foundations, subjected to increasing vertical load due to the gravity load of buildings. The study also considers slopes under closely spaced ... -
