PAH i forurenset sediment: Utredning av egnethet av PAHkomponenter/ grupperinger for vurdering av tiltaksbehov
(Research report, 2015)I Norge er det utarbeidet klassegrenser for til sammen 16 PAH-forbindelser i sediment og vann. Grenseverdiene baserer seg på kunnskap om toksisitet av de ulike stoffene og hva som er akseptabel eksponering for miljøet. I ... -
PANDALP : a new penetrometer for snow investigation
(NGI Publication;203, Chapter, 1998)This paper presents a new tool for snow investigation, issued from a portable dynamic penetrometer Panda with variable energy for soil investigation. After a brief presentation of this apparatus, a comparable study between ... -
Paper product production identified as the main source of per- and polyfluoroalkyl substances (PFAS) in a Norwegian lake: Source and historic emission tracking
(Peer reviewed; Journal article, 2020)The entirety of the sediment bed in lake Tyrifjorden, Norway, is contaminated by per- and polyfluoroalkyl substances (PFAS). A factory producing paper products and a fire station were investigated as possible sources. Fire ... -
Parameterization of a numerical 2-D debris flow model with entrainment: a case study of the Faucon catchment, Southern French Alps
(Journal article, 2012)The occurrence of debris flows has been recorded for more than a century in the European Alps, accounting for the risk to settlements and other human infrastructure that have led to death, building damage and traffic ... -
Particle simulation of snow avalanche motion
(Journal article, 1984)The continuum model of a snow avalanche is abandoned, and instead an avalanche is modeled as a collection of particles that move randomly and independently subject to gravity and resistive forces which have a random ... -
Passive-Sampler-Derived PCB and OCP Concentrations in the Waters of the World─First Results from the AQUA-GAPS/MONET Network
(Peer reviewed; Journal article, 2023)Persistent organic pollutants (POPs) are recognized as pollutants of global concern, but so far, information on the trends of legacy POPs in the waters of the world has been missing due to logistical, analytical, and ... -
Peatland Volume Mapping over Resistive Substrates with Airborne Electromagnetic Technology
(Peer reviewed; Journal article, 2019)Despite the importance of peatlands as carbon reservoirs, a reliable methodology for the detection of peat volumes at regional scale is still missing. In this study we explore for the first time the use of Airborne ... -
Pelefundamentering av kraftmaster og snøskredforbygninger i skrått terreng - Sluttrapport
(Research report, 1993-02-03)Prosjektet har gått ut på å undersøke muligheten av bruk av peler for å fundamentere snøskredforbygninger, kraftmaster oglignende konstruksjoner på løsmasser i bratt terreng. Siktemålet har først og fremst vært å gjennomføre ... -

Penetration Model for Installation of Skirted Foundations in Layered Soils
(Peer reviewed; Journal article, 2019)During installation of a skirted foundation, resistance to penetration is a combination of side and tip resistances. When penetrating a permeable soil unit, tip resistance in particular can be high but if seepage water ... -
Penzenlähner avalanche - calculation of maximum run-out of snow avalanches. Presentation of the results from the Norwegian working group
(Journal article, 1999)In order to find a probable run-out of extreme snow avalanches in the area east of HU:1gerburg of the Penzenlahnerlawine, we have used three different methods to calculate runout in the same manner as in Norway. The models ... -

Perception of risk in avalanche terrain
(The International Snow Science Workshop (ISSW) Proceedings;, Chapter, 2012)Although avalanche training and the risk minimization strategies have greatly evolved and are being widely taught to recreational and professional users, too many serious accidents continue to happen within the educated ... -
Permafrost response to environmental and industrial loads. Snø og snøskred på Svalbard. Registrering av snøforhold, snøskred og utløpslengder
(NGI-rapport;58910-04, Research report, 1999-12-30)Det er behov for forskning på snø og skred i arktiske områder for å kunne gi faglig verifiserte råd i forbindelse med utvikling og bruk av områdene. Problemstillinger og erfaringer fra ca 25 konsulentoppdrag på Svalbard ... -
Permafrost Thermal Dynamics and Cryostratigraphy at Villum Research Station, Station Nord, Eastern North Greenland (81°N)
