Klatrehøgder av skred på krumma leievoll
(NGI-rapport;58120-36, Research report, 2002-01-15)I krumma skredkanalar vil sentrifugalkrefter lyfta skredmassen opp langs kanalveggen i yttersving. Dette hender avdi sentrifugalkreftene roterer den frie overflata med ein vinkel θ (definert i Formel 1, s. 6). Klatrehøgda ... -
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 ... -
Snow avalanche research programme SIP-6. Ryggfonn. Full scale avalanche test site and the effect of the catching dam
(NGI-rapport;58120-35, Research report, 2002-02-28)The effect of the 16 m high retaining dam in Ryggfonn has been analysed by using data from 12 dry snow avalanches. Except for one avalanche, which was stopped by the dam, all of these avalanches overtopped it and ran ... -

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 ... -
EU program CADZIE. Road traffic and avalanches - methods for risk evaluation and risk management
(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. -
EU programme CADZIE. New concepts in avalanche hazard mapping
(NGI-rapport;20001018-02, Research report, 2003-06-16)The main goal of the CADZIE workpackage 1 is to improve the hazard assessment process by integrating uncertainty and to develop "best-fit" models. This goal can only be achieved if both the stochastic characteristics of ... -
