Riskcoast: A South-European approach for coastal landslide hazard: presentation and results

Abstract

RISKCOAST is a European project, co-funded by the South-West European (SudOE) Interreg V programme (https://riskcoast.eu), which aims to develop tools to prevent and manage coastal geological risks related to global warming: land movements mainly, but also other phenomena such as the evolution of water tables. The aim of this project is to study geological risks in coastal areas related to climate change, with a focus on improving the coordination and effectiveness of means of prevention, disaster management and rehabilitation of disaster areas. After a presentation of the whole project, we will focus on a specific site in the French Basque coast where a landslide impacts a very touristic area. An hydrogeomechanical model of the landslide is realized with FLAC3D and a parametric study is proposed to determine the most important parameters, and to define possible safety factor game value.
