Abstract

This study deals with the morphological evolution of this zone from 1978 to 2005, in particular the impact of the construction on the Northern intertidal mudflat at the mouth of the Seine estuary located between the new Le Havre port (Port 2000) and the Normandy bridge. The use of a low altitude remote sensing technique combined with traditional methods of ground survey and probes allow to demonstrate the impact of human activities on sedimentary and vegetation dynamics. The Northern mudflat of the estuary is the most affected by these human activities, which surface have reduced of 62% during the last 27 years with an intensified local erosion during the last 27 months. Results also establish that the response times of the sedimentary or topographic readjustment to an installation depend on the extent and the nature of the construction. In fact, the sedimentary readjustments to an installation can be delayed by up to 10 years in the case of the Seine estuary
