This paper proposes a model for assessing the risk posed by natural hazards to infrastructures, with a focus on the indirect losses and loss of stability for the population relying on the infrastructure. The model prescribes a three-level analysis wi

Various types of slope processes, mainly landslides and avalanches (snow, rock, clay and debris) pose together with floods the main geohazards in Norway. Landslides and avalanches have caused more than 2000 casualties and considerable damage to infra

The Norwegian Geotechnical Institute (NGI) has run full-scale avalanche experiments at the Ryggfonn test-site in Western-Norway for close to 40 years. The construction of an avalanche catching dam in 1981 laid the cornerstone of the so-called “Rygg

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 approaches such as the we

The Norwegian Geotechnical Institute (NGI) has been performing full-scale avalanche tests at Ryggfonn in western Norway for more than 30 years. During those years, measurements from about three dozen dry-snow avalanches have provided information on f

The paper summarizes measurements and observations of dry-snow avalanches at the Ryggfonn test-site with respect to their behavior in the runout area. Measurements of front velocities and retarding accelerations are presented and their probability di

Pulsed Doppler radar measurements from several avalanche releases are analyzed to gain an in-depth understanding of avalanche dynamics. A pulsed Doppler radar emits short pulses and samples the echo in distinct time intervals, corresponding to distan
