Description
Summary:Due to the issues related to the evolution of the seabed, the determination of the retreat or advancement of the ocean has been the subject of numerous scientific studies. Coastal areas are among the most dynamic places on the planet. Most of the coasts in the world are affected by the phenomenon of coastal erosion, in particular the coast of Benin. On the coast of Benin and in the Gulf of Guinea in general, the dynamics of the coastline is not a recent phenomenon but its scale has increased over the last decades. This erosion is the consequence of the impact of the swells. Identifying the causes of seabed dynamics in coastal areas is essential to understanding the physics of the phenomenon. This work emphasizes the different parameters that influence the morphodynamic evolutions of the beach and the coastline in this coastal area. The study is based on data obtained from the IRHOB (Institute of Halieutic and Oceanographic Research of Benin) of the CBRST (Benin Center for Scientific and Technical Research) on swells. This data was recorded with a time interval of 5 minutes; this allowed us to model the evolution of the coastline of the Benin coast. The results obtained show the major causes of the dynamics of the seabed on this coast in recent years.
