Risk analysis for landslides and snow avalanches. Example applications for snow avalanches
(NGI-rapport;522051-01, Research report, 1999-12-23)Prediction of snow avalanche occurrence and its run-out distance inherently involves many uncertainties. The main reason for the large uncertainties is that the mechanical behaviour of snow is extremely complicated, and ... -
Ryggfonn - Options for reconstruction of the test site. Deliverable of the NFR-Snow research programme SIP-6
(NGI-rapport;58120-34, Research report, 2001-01-31)Norges Forskningsråd (NFR) -
The Ryggfonn project. Avalanche data from the winters 1994/95 and 1995/96
(NGI-rapport;58120-32, Research report, 1997-12-20)This report presents data collected from the full-scale Ryggfonn project during the winters 1994/95 and 1995/95. Only four avalanches were observed in the course of these two winters, three of which were naturally released ... -
Shear stresses and boundary layers in snow avalanches
(NGI-rapport;581240-03, Research report, 1995-10-20)Full-scale experiments on snow avalanches have shown that the major part ofthe avalanches are mixed flow avalanches, and that they consist of at least two parts, a dense flow part and a turbidity part. The report is based ... -
Simulations of dense snow avalanches on deflecting dams
(NGI-rapport;58121-03, Research report, 1997-08-27)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 ofthe centre-of-mass ... -
SIP-6 snøskredforskning. Bruk av klimadatabaser for skredfareevaluering
(NGI-rapport;58810-23, Research report, 2002-01-29)Det er innhenta værdata fra 15 meteorologiske klimastasjoner i Norge. Disse dataene er behandla slik at de er relevante for vurdering av sannsynligheten for utløsning av snøskred. Det betyr at det er foretatt en glidende ... -
SIP6 snøskredforskning. Vær-, snø - og snøskred i Grasdalen. Vintrene 1994/1995 til 1999/2000
(NGI-rapport;20011001-05, Research report, 2001-10-29)Denne rapporten gir en oversikt over innsamlede vær-, snø- og snøskreddata fra skredforskningsstasjonen Fonnbu i Grasdalen på Strynefjellet. Oversikten omfatter vintrene 1994/1995, 1995/1996, 1996/1997, 1997/1998, 1999/2000. -
SIP8 - offshore geohazards and SIP6 - snøskredforskning. 3D- visualization of slides and the NIS slide model
(NGI-rapport;20021023-36, Research report, 2005-03-31)Numerical models are important tools for hazard assessment, and visualization is an important tool for pre-processing the input to those models and presenting results from the model runs. Visualization results address ... -
Skred- og klimadatabase. Statusrapport. Skreddatabase
(NGI-rapport;20041046 Notat 2005-01-07, Research report, 2005-01-07)Avdeling for skred og ingeniørgeologi ønsker gjennom prosjektet 20041046 å utvikle en database for lagring av skredinformasjon, samt et webbasert grensesnitt for registrering av skredinformasjon. Arbeid i prosjektet er ... -
Slushflow questionnaire
(NGI-rapport;58200-06, Research report, 1988-10-10)Questionnaires concerning slushflows were distributed globally. The purpose of the questionnaire was to determine the geographic distribution of slushflow activity as well as to collect information concerning most common ... -
Snow avalanche forecasting in Iceland and Norway
(NGI-rapport;581250-02, Research report, 1996-01-29)This document describes local avalanche warning and forecasting operations in Iceland and Norway, with the focus on forecasting as a preventive measure for communities with threatened habitations. The objective of an ... -
TIGRA. The integrated geological risk assessment. Hazard zoning methods of snow avalanches, debris flow and rock falls. Final report
(NGI-rapport;589210-03, Research report, 1997-11-20)The present report describes natural hazard zoning methods for snow avalanches in Norway and in some other countries were avalanches are a serious threat to the society. In addition methods for rock-fall and debris slide ... -
