The use of a numerical snow-drift model as a decision making tool in the planning of avalanche protection measures.
(The International Snow Science Workshop (ISSW) Proceedings;, Chapter, 2002)Blowing and' drifting snow is not only a major factor in the assessment of the acute avalanche danger, its contribution to the snow distribution also influences land-use planning. In many parts of alpine terrain end an ... -
Use of a Pre-Drilled Hole for Implementing Thermal Needle Probe Method for Soils and Rocks
(Journal article, 2016)The thermal needle probe method, which is widely used for measuring the thermal conductivity λ of soils, deploys a long and thin metallic probe that houses a line heater and a temperature sensor. However, inserting such ... -
The use of commercial cad software in snow avalanche run-out estimation
(The International Snow Science Workshop (ISSW) Proceedings;, Chapter, 2012)Linear infrastructures like highways and transmission lines often pass avalanche terrain both in remote and urban areas. In some cases these areas are quite wide, measured along the lines, and the number of avalanche paths ... -
Use of Daisybell and Snow Profiles to Investigate the Effect of Alpine Birch on Avalanche Release
(The International Snow Science Workshop (ISSW) Proceedings;, Chapter, 2014)Through a field study in Abisko, northern Sweden, we have used the artificial avalanche release system DaisyBell together with snow profiles to study the effect of alpine birch forest on avalanche formation. Evergreen ... -

Use of Multi-Criteria Involvement Processes to Enhance Transparency and Stakeholder Participation at Bergen Harbour, Norway
(Peer reviewed; Journal article, 2011)Use of participatory stakeholder engagement processes could be important to reduce the risk of potential conflicts in managing contaminated sites. Most stakeholder engagement techniques are qualitative in nature and require ... -
Use of numerical modelling when designing a full-scale field test of landfill top covers
(Lecture, 2023)Landfill closures typically include cover systems with a low-permeable barrier to limit the flow of water to and from the waste to minimize contamination of the surrounding environment. Commonly the lowpermeable barrier ... -
Use of the free fall cone penetrometer (FF-CPTU) in offshore landslide hazard assessment
(Chapter, 2018)Free fall penetrometer (FF-CPTU) testing can provide significant advantages over conventional CPTU investigation for shallow sub-surface offshore site investigations. Much work has been done on soil characterisation and ... -

Using eCognition Definiens for automated detection of snow avalanche deposits from very high resolution optical imagery - New developments
(NGI-rapport;20120096-01-TN, Research report, 2013-01-28)The identification of snow avalanche deposits from high resolution optical satellite imagery had been the focus of the project "avalRS” which NGI, together with the Norwegian Computing Centre and Statens Veivesen, had ... -
Using eCognition Definiens for automated detection of snow avalanches from optical imagery
(NGI-rapport;20110112 Notat 2012-07-14 Rev. 1, Research report, 2012-07-14)Detection of avalanches from remotely collected optical imagery has been tested through analysis of image properties such as brightness, contrast, and different measures of texture. There have been few publications on ... -
Using eCognition to automatically detect and map avalanche deposits from the spring 2009 avalanche cycle in the Tatra Mts., Slovakia
(Journal article, 2015)Here we present results from ongoing work where we apply an object oriented mapping algorithm developed in eCognition in order to automatically identify and digitally map avalanche deposits. The algorithm performance is ... -
Using geophysics on a terminal moraine damming a glacial lake: the Flatbre debris flow case,Western Norway
(Journal article, 2008)A debris flow occurred on 8 May 2004, in Fjǽrland, Western Norway, due to a Glacial Lake Outburst Flood and a natural terminal moraine failure. The site was investigated in 2004 and 2005, using pre- and post-flow aerial ... -
Using hydrogeological numerical modelling to predict drainage to excavations – findings from four Norwegian case studies
(NGI-rapport;20170774-D3.4, Research report, 2022-08-30)Urban ground work such as deep excavations performed in soft clay may cause damage to neighbouring buildings and structures as a consequence of settlements partly caused by drainage. The costs related to settlement damage ... -
Using local monitoring data for regional forecasting of weather-induced landslides in Norway
(Chapter, 2019)Since 2013, a national early warning system addressing weather-induced landslides in soils is operational in Norway. The system is based on real-time hydro-meteorological measurements used as input to a spatially distributed ... -
Using of GIS technology for avalanche hazard mapping, scale 1:10 000
(NGI Publication;203, Chapter, 1998)The sites with the size of 50·50 m2 having a various probability of avalanche formation were revealed for a given territory covering an area of 3·4 km2. Crossclassification of sites considering their slopes and snow cover ... -
Using Passive Samplers to Track per and Polyfluoroalkyl Substances (PFAS) Emissions From the Paper Industry: Laboratory Calibration and Field Verification
(Peer reviewed; Journal article, 2021)Per and polyfluoroalkyl substances (PFAS) are becoming more stringently regulated and as such, a more diverse suite of environmental monitoring methods is needed. In this work a polar organic chemical integrative sampler ... -
Using REACH registration data to rank the environmental emission potential of persistent and mobile organic chemicals
(Journal article; Peer reviewed, 2018)Organic chemicals that are persistent and mobile in the aquatic environment exhibit a hazard to contaminate drinking water resources. In this study an emission score model was developed to rank the potential of substances ... -
