A short comparison between Voellmy-fluid and Criminale-Ericksen-Filby-fluid dense snow avalanche models
(NGI Publication;203, Chapter, 1998)In the publications Norem et al. (1987) and Norem et al. (1989) a dense snow avalanche model is proposed that uses a Criminale-Ericksen-Filby constitutive relation with power law viscosity functions. A vertical velocity ... -
Significance of historical records for avalanche hazard zoning in Norway
(The International Snow Science Workshop (ISSW) Proceedings;, Chapter, 2000)In avalanche hazard zoning, it is common practice to investigate the previous avalanche history for the area considered. Historical observations of avalanches serve as an aid in the classification of the terrain, and may ... -
Significant build-up of soil organic carbon under climate-smart conservation farming in Sub-Saharan Acrisols
(Journal article; Peer reviewed, 2019)Conservation farming (CF) involving minimumtillage, mulching and crop rotation may offer climate change adaptation and mitigation benefits. However, reported effects of CF, as applied by smallholders, on storage of soil ... -
Sikringsmetoder mot snøskred
(Chapter, 1979)I store deler av landet vårt har vi omrader vi ønsker å utbygge, men hvor det samtidig er mulighet for snøskred. I de fIeste tilfellene der man er klar over snøskredfaren, unnlater man a føre opp bygninger. Der det allerede ... -
Sikringstiltak mot snø- og sørpeskred
(Byggforskserien - Planløsning;Sending 1, Chapter, 1995)Dette bladet behandler de vanligste tiltakene for å sikre bebyggelse mot snø- og sørpeskred. Hensikten med bladet er å gi en oversikt over mulige sikringsmetoder. Bladet gir ikke detaljerte data for prosjektering og ... -
Simplified computational methods for estimating dynamic impedance of batter pile groups in homogeneous soil
(Peer reviewed; Journal article, 2021) -
Simulating low frequency sound transmission through walls and windows by a two-way coupled fluid structure interaction model
(Peer reviewed; Journal article, 2017)Aircraft, supersonic flights, blasts, and explosions emit sound with substantial energy below 100 Hz. When the low frequency sound is transmitted inside a building, it generates vibration and rattling that may lead to ... -
Simulating run-up on steep slopes with operational Boussinesq models; capabilities, spurious effects and instabilities
(Peer reviewed; Journal article, 2013) -
Simulating tsunami propagation in fjords with long-wave models
(Journal article, 2015)Tsunamis induced by rock slides constitute a severe hazard towards coastal fjord communities. Fjords are narrow and rugged with steep slopes, and modeling the short-frequency and high-amplitude tsunamis in this environment ... -
Simulation of snow-avalanche flow in run-out zones.
(Journal article, 1989)The authors of this paper have previously, in 1987, outlined the development of a set of constitutive equations representing the behaviour of avalanching snow, and the resulting equations for fully developed steady shear ... -
Simulations of dense snow avalanches on deflecting dams
(Journal article, 1998)Two models simulating snow avalanches impacting retaining dams at oblique angles of incidence are presented. First, a lumped-mass model applying the Voellmy-Perla equation is used to calculate the path of the centre-of-mass ... -
Site characterisation and some examples from large scale testing at the Klett quick clay research site
(Peer reviewed; Journal article, 2019)The Klett research site was developed in conjunction with the new E6 developments south of Trondheim, Norway. The site comprises non-sensitive clay to about 6 m to 8 m and quick clay with significant silt lenses below this ... -
Site-specific soil reaction model for monopiles in soft clay based on laboratory element stress-strain curves
(Peer reviewed; Journal article, 2020)Large-diameter monopiles are the predominant foundation solution for supporting offshore wind turbines. They are conventionally designed using soil reaction curves developed for long slender piles used for supporting ... -
Skred og skredfare
(NGI Publikasjon;122, Journal article, 1978)Allerede samme år som NGI offisielt ble opprettet fikk man i oppdrag å undersøke kvikkleireskredet som gikk på Bekkelaget ved Oslo 7. oktober 1953... -
Skred og skredforskning i Norge
(Chapter, 1999)Siden man begynte offentlig registrering over årsak til dødsulykker i 1835, har ca. 1500 mennesker satt livet til i ulykker som skyldes snøskred eller sørpeskred i Norge. I Alpelandene var man også vel vant med den hvite ... -
Skredfare, boligplanlegging og ekspertens rolle overfor oppdragsgiver
(Journal article, 1978)Trange dalfører og bratte fjellsider er svært vanlig i vårt land og i fjord. og dalstrØkene særlig pA Vestlandet og i Nord-Norge er naturødeleggelse i fonn av skred en realitet. I mange dalfører er f.eks. gArdsbebyggelsen ... -
The SLAB test - The missing link in stability testing?
(The International Snow Science Workshop (ISSW) Proceedings;, Chapter, 2010)An avalanche is released when both the weak layer and the slab fails, still standard stability tests (e.g. CT, ECT) focus on the weak layer only. The SLAB test gives information on both the weak layer and the slab, hence ... -
Slush-flow questionnaire.
(Journal article, 1989)Questionnaires concerning slush flows were distributed globally. The purpose of the questionnaire was to determine the geographic distribution of slush-flow activity and also to collect information concerning the most ... -
Slushflow Formation, Flow Regimes and Consequences (Short Version)
(The International Snow Science Workshop (ISSW) Proceedings;, Chapter, 2012)The term ‘slushflow’ was introduced by Washburn and Goldthwait (1958). Eight people perished in slushflows during the winters 2010 and 2011 in Norway, five in backcountry, two in their home and one truck-driver. Buildings, ...
