Snow avalanche speed determination using seismic methods
(Journal article, 2007)We present a new method to determine the average propagation speed of avalanches using seismic techniques. Avalanche propagation speeds can reach 70 m/s and more, depending on a wide range of factors, such as the characteristics ... -
Snow Avalanches
(Chapter, 2004)Snow avalanches represent a threat to societies in many countries of the world. In America, Asia, Australia, and Europe, several mountainous countries are affected by this type of natural hazard. People, housing areas, ... -
Snow cover spatial variability at multiple scales: Characteristics of a layer of buried surface hoar
(Journal article, 2007)With the aim of a multi-scale analysis, we simultaneously observed snowpack stratigraphy and stability at three scales: the slope scale, the regional scale and the mountain range scale. The minimum spacing between measurements ... -
Snow creep pressure on mast constructions
(The International Snow Science Workshop (ISSW) Proceedings;, Chapter, 1990)In Norway snow-creep quite often causes damage on mast constructions on hillsides exposed to deep snow-cover. An extensive snow-creep measurement program has therefore been carried out for different constructions at NGI's ... -
Snow drift challenges at Klettsháls mountain road pass in Iceland
(The International Snow Science Workshop (ISSW) Proceedings;, Chapter, 2014)Snow fences are usually used to control snowdrift problems on a relatively flat and open terrain. Snowdrift problems on mountain roads and passes are normally more challenging. The terrain is often more complex, winds can ... -
Snow mass quantification and avalanche victim search by ground penetrating radar
(Journal article, 2003)Ground penetrating radar (GPR) systems can be used in many applications of snow and ice research. The information from the GPR is used to identify and interpret layers, objects and different structures in the snow. A ... -
Snow Pressure on Rigid Obstacles
(Journal article, 1976)In this paper a continuum mechanical formulation of snow pressure is given. The snow pressure against retaining structures on slopes is considered in two separate parts: (1) the static component due to the regression of ... -
Snow thickness profiling on Antarctic sea ice with GPR—Rapid and accurate measurements with the potential to upscale needles to a haystack
(Peer reviewed; Journal article, 2017)Snow thickness on sea ice is a largely undersampled parameter yet of importance for the sea ice mass balance and for satellite-based sea ice thickness estimates and thus our general understanding of global ice volume change. ... -
Snow-creep pressure on masts
(Journal article, 1989)Snow-pressure measurements have been carried out on two masts at the NGI avalanche station in Grasdalen, western Norway. These two tubular masts have diameters of 0.22 and 0.42 m, respectively, and are situated on a 25° ... -
The snowdrift pattern around a small hill in the High Arctic
(Chapter, 2000)The snow distribution in complex terrain is important for the planning of infrastructure, so that large snow depths can be avoided in residential areas and in connection with roads and railroads. Numerical models can give ... -
The snowdrift pattern around two cubical obstacles with varying distance. Measurements and numerical simulations.
(Chapter, 2000)Snowdrifts around buildings can cause serious problems when formed on undesirable places. The formation of snowdrifts is highly connected to the wind pattern around the building, and the wind pattern is again dependent on ... -
Snowmelt and slush avalanches / slushflows in nothern mountains, Sweden. A video presentation.
(NGI Publication;203, Chapter, 1998)A video of 15 minutes duration reviews different cases of slushflows in May-June 1995 and their behaviour during release and downslope propagation. Slushflow dynamics are compared with other types of mass movement. -
Snowmelt contribution to Arctic first-year ice ridge mass balance and rapid consolidation during summer melt
(Journal article, 2023)Sea ice ridges are one of the most under-sampled and poorly understood components of the Arctic sea ice system. Yet, ridges play a crucial role in the sea ice mass balance and have been identified as ecological hotspots ... -
Snøskred og vurdering av snøskredfare
(Chapter, 1976)Artikkelen gir først en kort historikk av snøskredforskning i Norge. Den er nå organisert ved Norges Geotekniske Institutt som har etablert en fast forskningsstasjon i høyfjellet. Deretter er det redegjort for de viktigste ... -
Snøskred trenger ikke komme som noen overraskelse
(Journal article, 2000)Snøskred er kostbare hendelser, i form av tap av liv eller materielle skader. Mange steder i landet vårt er det topografiske og klimatiske forhold som gjør det naturlig at det oppstår skredfare. Faren kan normalt ikke ... -
Soft computing approach for prediction of surface settlement induced by earth pressure balance shield tunneling
(Peer reviewed; Journal article, 2020) -
Soil classification of NGTS sand site (Øysand, Norway) based on CPTU, DMT and laboratory results
(Chapter, 2018)The Norwegian GeoTest Site project (NGTS) established five research sites in Norway in 2016. The sites are referred to as sand, soft clay, quick clay, silt and permafrost. The project is funded by the Research Council of ... -
Soil mechanics and geology
