Skred, skråninger. Generelt. Thermodynamic equilibrium between ice and water in porous media
(NGI-rapport;50900-01, Research report, 1977-01-01)A derivation is given for the equation of thermodynamic equilibrium between ice and water in porous media. The equation accounts for a difference between the pressure of the ice phase and the total potential (in pressure ... -

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 ... -
Skredsøk ved bruk av magnetometer
(Research report, 2003)En innledende teoretisk analyse viser at den beste metoden for å detektere begravde ferromagnetiske gjenstander er ved å bruke to magnetometre montert i en fast avstand og å bruke forskjellen i måleverdi (gradienten) som ... -
Skredulykken under Håbergnuten, Svalbard
(NGI-rapport;58810-21, Research report, 2001-08-31)To menn som var ute og kjørte snøscootere ble tatt av et snøskred som løsnet i fjellsida opp mot fjellet Håbergnuten sør for Dryabreen i Fardalen ca. kl. 15:30 Søndag 4. februar 200 I. Skredet løsnet etter forutgaende ... -
Skredutløsning. Installasjonsrapport
(NGI-rapport;84425 Notat 1984-10-12, Research report, 1984)I uke 38/84 ble de koblingsbokser og forbindelses kabler som er beskrevet i rapport 84425 (se vedlegg 1) lagt ut og koblet sammen ute i terrenget (fjellsiden). Alle koblingsboksene og ledningene ble gravd ned i lyng og ... -
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, ... -
Slushflow hazard - where, why and when? 25 years of experience with slushflow consulting and research.
(Journal article, 1998)Slushflows — flowing mixtures of water and snow — are a major natural hazard in Norway. Knowledge gathered by the Norwegian Geotechnical Institute during 25 years of slushflow consulting and research is presented. The ... -
Slushflow hazard control. A review of mitigative measures.
(NGI Publication;203, Chapter, 1998)Slushflow hazard detection and control are based on both active and passive mitigative measures performed above and within the starting zones as well as along the path and in the runout zone. The main aim of preventive ... -
Slushflow hazard prediction and warning
(Journal article, 2004)Parameters critical to slushflow release have been studied during 11 winters in Rana, North Norway. Slushflows occurred during 16 periods within the research areas and during another 13 in the district. A noticeable rise ... -

Small strain stiffness within logarithmic contractancy model for structured anisotropic clay
(Peer reviewed; Journal article, 2021)Stiffness of soils in the small strain region is high and it decays nonlinearly with increasing shear strains or with mobilization of shear stresses. However, the commonly used critical state based constitutive models use ... -
Snaps - snow, ice and avalanche applications
