Contribution of physical modelling to landslide hazard mapping: case of the French Basque coast

In the frame of the DO-SMS project (created within the European SUDOE partnership), a new landslide hazard mapping method is experimented on the French “Pays Basque” coast. Based on a physical landslide modelling and integrated into a software named ALICE®, its aim is to propose a quantitative classification of landslide hazard by calculating a probability of occurrence of landslides on each point of the studied area. The method highlights a useful tool to gain time and efficiency in hazard mapping.
