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
(Chapter, 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
(Chapter, 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 ... -
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 ... -
Befaringsnotat Grandefonna, Geiranger
(NGI-rapport;20170131-14-TN, Research report, 2020-06-26)Grandefonna i Geiranger gikk 17. januar 2019 etter en periode med stort snøfall (NV-situasjon) og stengte vegen. I løpet av 3-5 dager i midten av januar kom det omkring 70-100 cm snø i området. Det var ikke spesielt mye ... -
Beregning av krefter mot horisontale elementer i snødekket.
