Résumé
Les effets catastrophiques de l’ouragan Katrina sur la Nouvelle-Orléans invitent à réexaminer les stratégies de protection mises en oeuvre jusqu’à présent contre les risques d’inondation auxquels cette ville a toujours été exposée. Le système de levées et les autres défenses matérielles établies au cours des décennies autour de l’agglomération ont clairement, une fois de plus, démontré leur inefficacité, et du même coup, l’insuffisance d’une protection essentiellement structurelle. Une voie complémentaire est à chercher, malgré les difficultés de l’entreprise, dans une organisation politique cohérente et une gestion administrative systémique visant à atténuer la vulnérabilité du site.

Abstract
The New Orleans disaster in the wake of Hurricane Katrina and Rita points to the need to reconsider the strategies for providing flood risk protection that have been implemented over the years in the flood-prone city. The levee system and other anti-flood equipment deployed during the past decades on sites throughout the city are clearly not efficient, and show the extent to which structures alone are insufficient for protection against flood events. Reducing site vulnerability is possible but difficult, and requires that a coherent political configuration be coupled with a systemic management approach.
