La vulnérabilité d’un territoire, un héritage complexe à révéler : démonstration à travers l’étude géohistorique du risque d’inondation en Val d’Orléans (France)

The present paper focuses on the optimization of flood risk prevention policies in Val d’Orléans. On that plain and in the whole Val de Loire, the consciousness of flood risk is not shared for most inhabitants and not even for some local actors. Nevertheless an impressive defense plan against the ri...
