Assessing the risk posed by natural hazards to infrastructures
(Peer reviewed; Journal article, 2017)This paper proposes a model for assessing the risk posed by natural hazards to infrastructures, with a focus on the indirect losses and loss of stability for the population relying on the infrastructure. The model prescribes ... -
Assessment of building damage due to excavation-induced displacements: The GIBV method
(Peer reviewed; Journal article, 2020)This paper presents an original methodology for the rapid assessment of “potential” building damage caused by an excavation. The combination of the Ground-work Impact (GI), in terms of induced greenfield displacements, and ... -
Assessment of CO2 storage capacity based on sparse data: Skade Formation
(Peer reviewed; Journal article, 2018)Large North Sea aquifers of high quality are the likely major target for 12 Gt of European CO2 emissions that should be stored in the subsurface by 2050. This involves an upscaling of the present combined injection rate ... -
Assessment of the impact of pile driving on slope stability
(Lecture, 2023)Driving piles near slopes can be challenging in terms of temporarily reducing slope stability, specifically in the presence of sensitive clay or lenses of sand and silt in the ground. There is currently no standard method ... -
Associations between shear strength of a buried surface hoar layer and stratigraphic, topographic and vegetation characteristics on a uniform slope. Extended abstract
(The International Snow Science Workshop (ISSW) Proceedings;, Chapter, 2006)In this study we quantify 1) changes in spatial and aspatial characteristics of the shear strength of a buried surface hoar layer, and 2) identify characteristics in terrain, vegetation and snow stratigraphy that can help ... -
Automated Avalanche Deposit Mapping From VHR Optical Imagery
(The International Snow Science Workshop (ISSW) Proceedings;, Chapter, 2012)Using eCognition we developed an algorithm to automatically detect and map avalanche deposits in Very High Resolution (VHR) optical remote sensing imagery acquired from satellites and airplanes. The algorithm relies on a ... -

The avalanche accident at Vassdalen, Norway, 5th March 1986
(Journal article, 1988)Shortly after 1300 hrs on wednesday March 5, 1986, a snow avalanche released from Storebalak, a mountain located at Vassdalen in Nordland county. The avalanche struck 31 men from the North Norway Brigade while they were ... -
The avalanche at Flateyri, Iceland October 26th 1995 and the avalanche history
(NGI Publication;203, Chapter, 1998)An avalanche struck the village Flateyri on 26.10.1995 killing 20 people. There was also an enormous property damage. The avalanche went further than previously known for avalanches from Skollahvilft. The weather conditions ... -
Avalanche caused catastrophes on the mountainous rivers
(NGI Publication;203, Chapter, 1998)Alongside with the danger of snow avalanching for the objects and population, the subsequent phenomena caused by the avalanching are not less serious. One of such reasons can be the choked lakes and outflash floods on the ... -
Avalanche characterization for regional forecasting
(The International Snow Science Workshop (ISSW) Proceedings;, Chapter, 2008)In the Sunnmøre and Romsdal road districts in Western Norway, the local road authorities have compiled a register of more than 300 sites where avalanches encounter principal roads in the area. The area covered is about 5 ... -
Avalanche control measures for roads in Norway
(Chapter, 1994)In a mountainous country like Norway the roads are exposed to different kind of natural hazards. Increasing traffic and extensive road-building programs the latest 25 years have made the society dependent on a relatively ... -
Avalanche debris detection using satellite-borne radar and optical remote sensing
(The International Snow Science Workshop (ISSW) Proceedings;, Chapter, 2014)The mountainous fjord landscape around Tromsø in Northern Norway is prone to high avalanche activity during the snow season. Large avalanches pose a hazard to infrastructure, such as buildings and roads, located between ... -
Avalanche defences for Flateyri, Iceland. From hazard evaluation to construction of defences.
(NGI Publication;203, Chapter, 1998)The village of Flateyri was hit by two major avalanches in 1995, with the latter one killing 20 of the 45 people caught in it. These, together with the catastrophic avalanche in the nearby Súôavík in January the same year, ... -
Avalanche forecasting and risk mitigation for specific objects at risk
(The International Snow Science Workshop (ISSW) Proceedings;, Chapter, 2013)Objects and individuals can be exposed to different levels of avalanche hazard. For objectspecific avalanche forecasting and risk mitigation programs, the general danger scales, such as the European and North American ... -
Avalanche forecasting for transportation corridor and backcountry in Glacier National Park (BC, Canada)
(NGI Publication;203, Chapter, 1998)The Avalanche Control Section at Rogers Pass is responsible for avalanche safety on the Trans Canada Highway and Canadian Pacific Railroad within Glacier National Park and for the daily issue of an avalanche warning bulletin ... -
An avalanche forecasting program based on a modified nearest neighbour method.
(The International Snow Science Workshop (ISSW) Proceedings;, Chapter, 1994)As a part of an avalanche forecasting system, a modified nearest neighbour program is described. The system is intended to be used with forecast values for most ofthe parameters. The modifications consist of 1) the use of ... -
Avalanche hazard mapping using numerical Voellmy-Fluid models
(NGI Publication;203, Chapter, 1998)One- and two-dimensional numerical dense-snow avalanche dynamics models using a Voellmy-fluid constitutive flow law have been developed in Switzerland recently. In order to apply these models in practice, they have been ... -
An avalanche index for roads
(Chapter, 2008)Several methods have been introduced through the years to evaluate avalanche risk along road sections. In 1988, Peter Schaerer introduced Avalanche Hazard Index, a numerical expression of damage and loss as the result of ...
