Un nouvel indicateur de prédisposition au risque d’érosion côtière, application en Manche et en Vendée (France)

Low sandy coasts are small and constrained spaces very sensitive to coastal hazards. The settlement of human activities next to the coastline sets up at-risk territories. The identification of territories exposed to coastal erosion is one of the objectives of the French national strategy for integra...
