Due to the global climate change an increase of heavy precipitation events on a regional scale is expected. Especially in Switzerland, damages from natural hazards resulting from heavy precipitation events occur every year. Damages arise from erosion and accumulation of bed load material or driftwood in mountain torrents and rivers. In mountain torrents, erosion of the embankments during high...

Deep landslides (> 10 m) are generally characterized by phases of acceleration alternating with periods of lull, but most often lack real stabilization. Due to the continuous movement, it is difcult to evaluate the evolution of the activity. Therefore, a new methodology has been developed in order to precisely identify the sub-recent (20th century) and present evolution of deep landslide...

Instabilité de terrain dans les Préalpes fribourgeoises (Suisse) au cours du Tardiglaciaire et de l'Holocène : influence des changements climatiques, des fluctuations de la végétation et de l'activité humaine

Slope instabilities such as mudflows, debris flows or landslides have lately raised much concern in Switzerland, since various major events have occurred during the last decade, resulting in major landscape disturbances, as well as costly damage to infrastructure. This demonstrated the necessity to better understand the causes and dynamics of such processes. This research work aims at defining...
