This work tackles the origin of the dry valleys of the tabular Jura of Ajoie (northwestern Switzerland) according to a new and multidisciplinary approach, in particular thanks to the geological information collected during the last twenty years in relation with the construction of the highway A16. Once the geomorphological framework has been set, the various morphogenetic hypothesis found in the...

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 difcult 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...

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...
