IFREMER, Sète

Abstract

Port activities require continuous or occasional dredging of considerable quantifies of sediments : approximately 50 million m³ along the French coastline. A large proportion of the dredgings is authorized for dumping at sea in geographically delimited areas and following an impact evaluation of their potential harmfulness to the marine environment. The environmental risks assessment linked to dredging operations relies on knowledge related to several scientific disciplines.
