Rockfall is a major threat to settlements and transportation routes in large parts of the Alps. While protective forest stands in many locations undoubtedly reduce rockfall risk, little is known about the exact frequency and spatial distribution of rockfall activity in a given place or about how these parameters can be assessed. Therefore, the objective of the present study was to reconstruct...

We used one of the few rockfall models explicitly taking trees into account and compared the results obtained with the 3D simulation model RockyFor with empirical data on tree impacts at three mountain forests in Switzerland. Even though we used model input data with different resolutions at the study sites, RockyFor accurately predicted the spatial distribution of trajectory frequencies at all...

La dendrochronologie a été utilisée pour étudier 25 ans d’activités de chutes de pierres sur le versant boisé de Täschgufer, à Täsch (Alpes suisses). Une nouvelle approche, basée sur l’apparition de tissu calleux et de canaux résinifères résultant d’impacts dus à des chutes de pierres, permet de déterminer la saison des événements. Les résultats issus de l’analyse de...
