This paper presents a GIS based methodological approach for landslide danger assessment, applied to the coast of Dakar. By the combination of analysis, interpretation, and evaluation of geo-morphological, geological and geotechnical data utilizing GIS, valuable ...

It is investigated whether a GIS-based distributed model developed for rockfall assessment at slope scale, which uses data with a support of 2.562.5 m, could be used for rockfall assessment at the regional scale, using input data with a support of 25625m and ...

Site-specific information about the level of protection that mountain forests provide is often not available for large regions. Information regarding rockfalls is especially scarce. The most efficient way to obtain information about rockfall activity and the ...

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 susceptible to failure can therefore be detected. Effects ...

Rockfall hazard assessment is not simple to achieve in practice and sound, physically based assessment methodologies are still missing. The mobility of rockfalls implies a more difficult hazard definition with respect to other slope instabilities with minimal ...
