Coastal erosion threatens human lifes, private properties and public substructures and buildings. Along the coast of Labourd (France), it is mainly the result of landslides. Previous studies show that most of the slidings occur in weathered rock (weathering of cretaceous marls and limestones with flysch facies), called alterites. In order to understand failure processes in these rocks, geological, geotechnical and hydrogeological context is studied. Weathered rocks are very heterogeneous silty clays with flints. The parent rock structure has been conserved although being compressed. At the base, the limestones are characterized by a karstic channels system containing in situ alterite. This level, called karstified level, constitutes the « r...
