Beregning av krefter mot horisontale elementer i snødekket.
Lied, Karstein; Bakkehøi, Steinar (NGI-rapport;75418-05, Research report, 1977-02-28)Norges Geotekniske Institutt har på oppdrag fra NVE - Statskraftverkene foretatt en teoretisk beregning av snøens vertikale belastning mot opphengte horisontale elementer nede i snødekket. Ved beregningen har man antatt ... -
Calculation of maximum snow-avalanche run-out distance by use of digital terrain models.
Lied, Karstein; Toppe, Ronald (Journal article, 1989)This paper discusses how maximum snow-avalanche run-out distance may be calculated by a combination of topographic parameters and use of a digital terrain model. Digitized maps are being made for extensive areas of Norway. ... -
Calculation of snow avalanche runout distance.
Bakkehøi, Steinar; Domaas, Ulrik; Lied, Karstein (Journal article, 1983)Evaluation of the maximum runout distance of snow avalanches is one of the most important problems in avalanche zoning. It is also one of the most difficult and controversial subjects in avalanche research. This is especially ... -
Can the propagation speed of snow avalanches be determined by seismic methods?
Vilajosana, I.; Khazaradze, G.; Lied, Karstein; Suriñach, E. (Chapter, 2004)The main question of the given work is whether the propagation speed of snow avalanches can be determined using seismic observations. The significance of having at least an order of magnitude estimate of this basic physical ... -
Can we learn more from the data underlying the statistical a-ß model with respect to the dynamical behavior of avalanches?
Gauer, Peter; Kronholm, Kalle; Lied, Karstein; Kristensen, Krister; Bakkehøi, Steinar (Journal article, 2010)Hazard and risk assessment in avalanche-prone areas involves estimation of runout distances of potential avalanches. Methods for determination of the runout may be divided into two categories: 1) methods based on statistical ... -
A comparison of avalanche models with data from dry-snow avalanches at Ryggfonn, Norway
Issler, Dieter; Harbitz, Carl Bonnevie; Kristensen, Krister; Lied, Karstein; Moe, Arne; Barbolini, M.; Khazaradze, G.; McElwaine, J.N.; Mears, A.I.; Naaim, M.; Sailer, R. (Chapter, 2005)Twelve well-documented dry-snow avalanches from the instrurnented Ryggfonn path in western Norway were selected for back-ca1culations with several dynamical avalanche models. In each case, the run-out distance, the front ... -
