Rockfall hazard mapping along a mountainous road in Switzerland using a GIS-based parameter rating approach
Rockfall hazard mapping a mountainous road Switzerland a GIS-based parameter rating approach
2009/12/10
A posteriori studies of rock slope instabilities generally show that rockfalls do not occur at random locations: the failure zone can be classified as sensitive from geomorphological evidence. Zones s...

A methodology of magnitude estimates for debris flow events is described using airborne LiDAR data. Light Detection And Ranging (LiDAR) is a widely used technology to generate digital elevation inform...
Regional evaluation of three day snow depth for avalanche hazard mapping in Switzerland
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...
Impacts of anthropogenic and environmental factors on the occurrence of shallow landslides in an alpine catchment (Urseren Valley, Switzerland)
anthropogenic and environmental factors shallow landslides an alpine catchment
2009/12/30
In this study, we explicitly consider the influence of dynamic human-induced changes on the occurrence of landslides in addition to natural factors. Our hypothesis was that if changes in land use and ...
