Halden research site - Site characterisation and engineering properties of Halden silt
(NGI-Rapport;20160154-05-R, Report, 2019-10-02)Halden silt site is property of Halden municipality and it is known locally as Rødsparken. As part of the fully characterization of Halden silt site during NGTS project, two main reports are prepared: 1) a factual report ... -
Halden research site: geotechnical characterization of a post glacial silt
(Peer reviewed; Journal article, 2019)This paper describes the geology and geotechnical engineering properties of the Halden silt; a 10–12 m thick deposit of fjord-marine, low plasticity clayey silt. Over the last six years, the test site has been well ... -

How to determine the environmental exposure of PAHs originating from biochar
(Journal article, 2016)Biochars are obtained by pyrolysing biomass materials and are increasingly used within the agricultural sector. Owing to the production process, biochars can contain polycyclic aromatic hydrocarbons (PAHs) in the high mg/kg ... -
Human error revisited
(The International Snow Science Workshop (ISSW) Proceedings;, Chapter, 2012)It is often reported that a majority of avalanche accidents, as well as accidents in other fields, are caused by human error. In these accident analyses, the accidents are attributed to the "human factor". This factor is ... -
Hvor forekommer snøskred og hvilken rekkevidde har skredene i dalbunnene?
(Chapter, 1979)Snøskred kan forekomme i nær sagt alle typer terreng, fordi snø og værforholdene i løpet av et langt tidsrum i vårt klimaområde kan bli så ekstreme og snødekket så labilt samrnensatt at snøskred kan utløses safremt terrenget ... -
Hvordan beskrive den totale miljøpåvirkningen fra gjenvinning av masser – mulige metoder
(NGI-rapport;20160794-11-R, Report, 2019-12-17)Hovedmålet med GEOreCIRC er å utvikle metoder som danner grunnlag for økt gjen-vinnning av: a) Restprodukter og overskuddsmasse som er lettere forurenset og som i dag blir ansett som et avfall b) Problemfraksjoner som ... -

Hydrochemical and biotic control on iron incrustations in groundwater heat pump systems: Case study from a saline, anoxic aquifer in Melhus, Norway
(Peer reviewed; Journal article, 2022)Clogging by incrustations of nine groundwater heat pump (GWHP) systems in Melhus, Norway have been investigated by field and laboratory methods for water quality and incrustation composition. Iron oxides incrust systems ... -
Hydrogeological characterization of an alpine aquifer system in the Canadian Rocky Mountains
(Peer reviewed; Journal article, 2020)Groundwater storage in alpine regions is essential for maintaining baseflows in mountain streams. Recent studies have shown that common alpine landforms (e.g., talus and moraine) have substantial groundwater storage capacity, ... -
Hydrogeological report

Hydrometeorological threshold conditions for debris flow initiation in Norway
(Journal article, 2012)Debris flows, triggered by extreme precipitation events and rapid snow melt, cause considerable damage to the Norwegian infrastructure every year. To define intensity-duration (ID) thresholds for debris flow initiation ... -
Icelandic avalanche run out models compared with topographical models used in other countries
(NGI Publication;203, Chapter, 1998)A statistical topographical model for the computation of runout for snow avalanches in Iceland has been derived from a recently assembled data sel of long Icelandic snow avalanches. The avalanches are from hills above towns ...
