Coastal protection and development, coastal engineering

In view of current forecasts of climate change and rises in sea levels, the protection of sensitive coastal zones is having to be rethought. Familiar with the issues of coastal erosion, Artelia designs and supervises the implementation of sustainable coastline management projects in various countries. Artelia was appointed to supervise beach nourishment works in the gulf of Aigues-Mortes (France). A comprehensive operational hydro-sedimentary model of the Mont-Saint-Michel Bay (France) built with the Telemac system is supporting work to restore the maritime nature of the Mount. Artelia is currently carrying out a coastal protection study in Congo and designing coastal protection works at Cap Lopez in Gabon using physical and numerical hydrosedimentary mathematical models. For the causeway linking Qatar to Bahrain, Artelia is responsible for auditing the hydraulic and environmental studies.
