Impact study of sediment dumping at sea

Capbreton (France)

 

Client : Communauté de communes de Maremnes Adour Côte-Sud (MACS)

Date of completion : 2020 - 2021



In order to study the environmental impact of sediment dumping off Capbreton, Globocean has performed the numerical modelling of the sediment plumes and seabed accumulations.


The following steps were followed during the realization of this study :

  • Numerical modelling of the offshore waves,

  • Hydro-sediment modelling of the sediment concentrations and seabed accumulations,

  • Study of the sediment plume spreading according to meteorological scenarios,

  • Simulations of sediment dumping operations and analysis of the impact on the sensitive areas.
