Laboratory procedures and standards for the NGTS project
(NGI-Rapport;20160154-02-R, Report, 2019-12-03)This report gives an overview of the laboratory testing procedures used in the NGTS project. -
Landslide displacement prediction based on wavelet transform and long short-term memory neural network
(Chapter, 2019)The prediction of landslide displacement is a key component of an early warning system to mitigate landslide risk. Most of the models for landslide displacement prediction are static models. Yet, landslides move dynamically. ... -
Landslide Material Control on Tsunami Genesis ‐ The Storegga Slide and Tsunami (8100 y BP)
(Peer reviewed; Journal article, 2019)Tsunami generation from sub‐aqueous landslides is controlled by landslide kinematics, which in turn is governed by the material properties of the slide mass. Yet, the effect of the material properties on tsunami‐genesis ... -
Landslide Risk in Hong Kong under Extreme Storms
(Chapter, 2018)Landslides are a major hazard in Hong Kong which can lead to loss of life, injury to people, or economic losses. This paper assesses the landslide risk in western part of Hong Kong Island under extreme rainstorms of 29%, ... -
Landslides Susceptibility of Chittagong City, Bangladesh and Development of Landslides Early Warning System
(Chapter, 2018)Chittagong, the second largest city of Bangladesh, is mostly developed in the hilly areas. Hills are mostly covered with loose and weathered tertiary sedimentary rocks susceptible to landslides. Generally, during heavy ... -
Large scale driving of concrete piles in stiff to very stiff clay
(Chapter, 2016)BAMA Gruppen AS have constructed a new 44 000 m2 warehouse, office and distribution centre in Groruddalen in northern parts of Oslo, Norway. Norwegian Geotechnical Institute (NGI) were employed as geotechnical consultants, ... -
Layering in shales controls microfracturing at the onset of primary migration in source rocks
(Peer reviewed; Journal article, 2020)The process of primary migration, which controls the transfer of hydrocarbons from source to reservoir rocks, necessitates the existence of fluid pathways in low permeability sedimentary formations. Primary migration starts ... -
Leachate emissions of short- and long-chain perand polyfluoralkyl substances (PFASs) from various Norwegian landfills
(Peer reviewed; Journal article, 2019)Restrictions on the use of long-chain per- and polyfluoralkyl substances (PFASs) has led to substitutions with short-chain PFASs. This study investigated the presence of four short-chain PFASs and twenty-four long-chain ... -
Leaching and transport of PFAS from aqueous film-forming foam (AFFF) in the unsaturated soil at a firefighting training facility under cold climatic conditions
(Peer reviewed; Journal article, 2019)The contaminant situation at a Norwegian firefighting training facility (FTF) was investigated 15 years after the use of perfluorooctanesulfonic acid (PFOS) based aqueous film forming foams (AFFF) products had ceased. ... -
Lessons learned from the 2015 Soerkjosen shoreline landslide in Norway
(Chapter, 2017)Soft and partly sensitive clays along the fjords of northern Norway pose a challenge for infrastructure. Learning from failures is essential in providing guidelines for future geotechnical work in such areas. A shoreline ... -
Life-cycle assessment of biochar production systems in tropical rural areas: Comparing flame curtain kilns to other production methods
(Peer reviewed; Journal article, 2017)A life-cycle assessment (LCA) using end point methods was performed for the generation and sequestration of one kg biochar by various pyrolysis methods suitable for rural tropical conditions. Flame curtain kilns, a novel, ... -
Limited mobility of dioxins near San Jacinto super fund site (waste pit) in the Houston Ship Channel, Texas due to strong sediment sorption
(Peer reviewed; Journal article, 2018)Sediments from a waste pit in Houston Ship Channel (HSC) were characterized using a number of molecular markers of natural organic matter fractions (e.g., pyrogenic carbon residues, PAHs, lignins), in addition to dioxins, ... -
Local avalanche warning in Europe
(Lecture, 2018)Avalanche exposed settlements, communication lines, ski resort operations, construction sites, tourism and professional guiding are only few examples of activities in the mountains where an active risk management requires ... -
Los suelos marinos de la Sonda de Campeche y Litoral Tabasco, Golfo de México
(Chapter, 2019)En la Sonda de Campeche y Litoral Tabasco, Golfo de México, se han realizado más de mil sondeos geotécnicos y dos mil estudios geofísicos. Los sondeos tienen diversos objetivos, tales como: diseño de cimentaciones para ... -
Main aspects of deformation and rock support in Norwegian road tunnels
(Journal article; Peer reviewed, 2019)The general geology of Norway makes most of its tunnels to be constructed mainly in strong rock intersected by weakness zones of different sizes and characteristics. The Norwegian support tradition is, to the largest degree ... -
Mapping tsunami impacts on land cover and related ecosystem service supply in Phang Nga, Thailand
(Journal article, 2013)The 2004 Indian Ocean tsunami caused damages to coastal ecosystems and thus affected the livelihoods of the coastal communities who depend on services provided by these ecosystems. The paper presents a case study on ... -
Maximum frontal speeds, alpha angles and deposit volumes of flowing snow avalanches
(Peer reviewed; Journal article, 2018)Approximate maximum frontal speeds from 89 snow avalanches were analyzed to yield probabilistic estimates of maximum speed scaled with path length parameters. In addition to speeds, 88 companion values of runout for the ... -
Metagenomics in CO2 Monitoring
(Journal article, 2013)Leakage from CO2 storage areas is likely to affect the microbial communities in the overlaying sediments. We have conducted a baseline characterization of the microbial communities present in the surface sediments overlaying ... -
