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 ... -
Penetration and retrieval forces during sampling in a very soft clay
(Peer reviewed; Journal article, 2021) -
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 ... -
Per- and polyfluoroalkyl substance (PFAS) removal from soil washing water by coagulation and flocculation
(Peer reviewed; Journal article, 2024) -
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 Thermal Dynamics and Cryostratigraphy at Villum Research Station, Station Nord, Eastern North Greenland (81°N)
(Peer reviewed; Journal article, 2022)We provide the northernmost permafrost thermal analysis in Greenland through the ground temperature time series (2014–2021) and cryostratigraphy of two 20-m deep boreholes (SN1 and SN2) at Villum Research Station, Station ... -
Permissible range of model parameters for natural fine-grained materials
(Peer reviewed; Journal article, 2017)This paper presents a three-dimensional constitutive model for natural clay that includes creep, anisotropy and structure, as well as a theoretical means to estimate the range for anisotropy- and structure-related parameters, ... -
Persistent, mobile and toxic (PMT) and very persistent and very mobile (vPvM) substances pose an equivalent level of concern to persistent, bioaccumulative and toxic (PBT) and very persistent and very bioaccumulative (vPvB) substances under REACH
(Peer reviewed; Journal article, 2020)Under the EU chemicals regulation REACH (Registration, Evaluation, Authorisation and Restriction of Chemicals EC 1907/2006), registrants are not obliged to provide information related to intrinsic substance properties for ... -
Perspectives on snow avalanche dynamics research
(Peer reviewed; Journal article, 2021) -
Petrophysical Analysis And Rock Physics Diagnostics Of Sognefjord Formation In The Smeaheia Area, Northern North Sea
(Lecture, 2018)This study focuses on petrophysical characterization and rock physics diagnostics of the reservoir sandstones of Sognefjord Formation in the Smeaheia area that penetrated by an exploration well 32/4-1. The large scale CO2 ... -

Physical modelling of pile drilling in sand
(Peer reviewed; Journal article, 2021)Drilling for foundation piles and tieback anchors through soils using a continuous casing to support the borehole is often referred to as "overburden drilling". Monitoring data from several case studies show that overburden ... -
Physically-based landslide assessment for railway infrastructure

Piezoprobe test interpretation on soft clay
(Chapter, 2017)This paper describes and compares different methods to interpret dissipation tests on soft clays by using piezoprobe tests. Emphasis is given to estimate initial pore-water pressure (ui), in situ equilibrium pore-water ... -
Plenary: Progress of living with landslide risk in Europe
(Chapter, 2014)The need to protect people and property with a changing pattern of landslide hazard and risk caused by climate change and changes in demography, and the reality for societies in Europe to live with the risk associated with ...
