Discrimination of hot versus cold avalanche deposits: Implications for hazard assessment at Mount Meager, B.C.
hot versus cold avalanche deposits hazard assessment Mount Meager, B.C.
2009/12/10
The surficial deposits surrounding the Mount Meager volcanic complex include numerous avalanche deposits. These deposits share many attributes: (a) they are nearly monolithologic and comprise mainly i...
Nearest neighbour models for local and regional avalanche forecasting
Nearest neighbour models local and regional avalanche forecasting
2009/12/9
This paper presents two avalanche forecasting applications NXD2000 and NXD-REG which were developed at the Swiss Federal Institute for Snow and Avalanche Re-search (SLF). Even both are based on the ne...
A new method for avalanche hazard mapping using a combination of statistical and deterministic models
avalanche hazard mapping statistical and deterministic models
2009/12/9
The purpose of the present paper is to propose a new method for avalanche hazard mapping using a combination of statistical and deterministic modelling tools. The methodology is based on frequency-wei...

A joint experiment was carried out on 10 February 1999 by the Swiss Federal Institute for Snow and Avalanche Research (SFISAR) and the Austrian Institute for Avalanche and Torrent Research (AIATR, of ...
Observations and modelling of snow avalanche entrainment
snow avalanche entrainment avalanche events
2009/12/9
In this paper full scale avalanche dynamics measurements from the Italian Pizzac and Swiss Vallée de la Sionne test sites are used to develop a snowcover entrainment model. A detailed analysis of thre...
Possible deviations from Griffith’s criterion in shallow slabs, and consequences on slab avalanche release
Griffith’s criterion shallow slabs slab avalanche release
2009/12/9
Possible reasons for deviations from Griffith’s criterion in slab avalanche triggerings are examined. In the case of a major basal crack, we show (i) that the usual form of Griffith’s criterion is val...

Regional evaluation hazard mapping Switzerland
2009/12/30
The distribution of the maximum annual three day snow fall depth H72, used for avalanche hazard mapping according to the Swiss procedure (Sp), is investigated for a network of 124 stations in the Alpi...
Application of a regional approach for hazard mapping at an avalanche site in northern Italy
Application regional approach hazard mapping avalanche site northern Italy
2010/1/27
The currently adopted approach to avalanche hazard mapping in northern Italy includes avalanche dynamic modelling, coupled with statistical analysis of snow depth at avalanche start. The 30-years and ...

Avalanche risk assessment multi-temporal approach results
2009/12/29
Snow avalanches pose a threat to settlements and infrastructure in alpine environments. Due to the catastrophic events in recent years, the public is more aware of this phenomenon. Alpine settlements ...
The long-term development of avalanche risk in settlements considering the temporal variability of damage potential
long-term development avalanche risk temporal variability damage potential
2009/12/29
Recent studies on the avalanche risk in alpine settlements suggested a strong dependency of the development of risk on variations in damage potential. Based on these findings, analyses on probable max...
