Combinaison d'un projet portuaire et d'un projet environnemental d'amorce de réhabilitation de l'estuaire de la Seine

Abstract

ABSTRACT Port 2000 consists in developing a new site with harbour facilities designed to receive the largest container vessels under optimum conditions. Situated on the extreme north-west tip of the Seine estuary, the works take into account an estuarine environment forming an habitat which is interfacial in nature (involving river, land and marine environments), enabling the simultaneous existence of a wide range of complementary biotopes (sand banks, mudflats either bare or colonized by plants, marshes and wetlands), thereby ensuring the cohesion of the food chain. As a result of the evolution of the estuary, the most fragile and most threatened link in the food chain appears to be that formed by the bare mudflats, found at a level between the mean sea level and the high tide level. The Port 2000 project includes supportive environmental measures (45,74 M€ i.e. 300 MF) included themselves in a global management plan for the whole of Seine Estuary with notably the starting of a true rehabilitation over t...
