Perception sectorielle face À la nécessité d’une vision globale et partagée de l’estuaire de la Seine

The estuary of the Seine is a continuum between its upstream part (the watershed and its input in the hydrological system) and the downstream part (the Seine Bay and the eastern part of the English Channel). However, according to, their sensitivities, scientists, administrators or policy makers cons...
