    • Analyse av værforhold ved utvalgte skredsituasjoner i Ørsta 

      Christianidis, s.; Lied, Karstein; Bakkehøi, Steinar (NGI-rapport;58308-22, Research report, 1981-03-17)
      The meteorological phenomena of avalanches in Nivane, ørsta, Norway, for the period from 1960 to 1980 and for the years 1941 and 1942 have been analysed. We have analysed the meteorological phenomena of some situations ...

    • Avalanche studies and model validation in Europe, SATSIE. 3. Annual report 

      Issler, Dieter (NGI-rapport;20021048-11, Research report, 2005-12-01)

    • EU program CADZIE. Road traffic and avalanches - methods for risk evaluation and risk management 

      Harbitz, Carl Bonnevie (NGI-rapport;20001289-04, Research report, 2003-05-22)
      This report covers current methods that may be used to analyse and manage risks related to avalanches and road traffic. Avalanche types considered are primarily snow avalanches and rockslides.

    • Kartlegging av snøskred- og steinsprang ved hjelp av EDB baserte metoder 

      Toppe, Ronald; Lied, Karstein (NGI-rapport;58930-03, Research report, 1984-12-15)
      For å unngå at boligfelt planlegges i skredfarlig terreng er det satt i gang kartlegging av områder utsatt for snøskred- og steinskredfare i Norge. Kartleggingen er basert på topografiske kart i målestokk 1:50.000. Disse ...

    • Particle simulation of snow avalanche motion 

      Perla, R.; Lied, Karstein; Kristensen, Krister (Journal article, 1984)
      The continuum model of a snow avalanche is abandoned, and instead an avalanche is modeled as a collection of particles that move randomly and independently subject to gravity and resistive forces which have a random ...

    • The Ryggfonn project. Description of instrumentation and data registration system 

      Kvisterøy, Terje (NGI-rapport;58120-03, Research report, 1983-06-10)
      The Ryggfonn avalanche path has been instrumented to measure: deflections on a 6 m high steel mast mounted at top of the test embankment by means of weldable strain gauges; wind speed of powder snow fronts by means of a ...

    • Snow avalanche damages in Norway 1982/83 

      Kristensen, Krister (NGI-rapport;58810-06, Research report, 1983-09)
      The report constitutes part of the effort in the field "snow avalanche mechanics" described in the long range research plan for ngi, 19 82- 86 (res earch area 4, program 4.2.)

    • Snow avalanche damages in Norway 1983/84 

      Kristensen, Krister (NGI-rapport;58810-08, Research report, 1984-12-27)
      The report constitutes part of the research effort in the field "slides and avalanches" described in the long range research plan for NGI 1985-1989 (research area 2, program 2.4).

    • Snøskredskader i Norge 1982/83 

      Kristensen, Krister (NGI-rapport;58810-5, Research report, 1983-09)
      Rapporten beskriver en del av den forskning som pågår innen feltet "snømekanikk og snøskredteknikk" som er forskningsfelt nr. 4 i NGIs langtidsplan for perioden 1982-1986.

    • Statistical and geometrical definition of snow avalanche runout 

      Martinelli, M. Jr.; McClung, D.M.; Lied, Karstein (Journal article, 1987)
      Two mathematical models for calculating the extreme avalanche runout from a fixed reference point on the path are presented and contrasted. The models are: (1) estimates of confidence limits on regression analyses of ...

    • Vær-, snø- og skredobservasjoner i Grasdalen. En sammenfatning 

      Bakkehøi, Steinar (NGI-rapport;58110 R, Research report, 1983-09-29)
      Observasjonene i Grasdalen gjøres på en mest mulig standardisert måte. Metodikken for værobservasjonene er henta fra Meteorologisk Institutts "Håndbok for meteorologiske observatører 1" og "Meteorologiske koder, synop". ...
