Rapid.population growth and.major trend. of world.economy growth have led.to significant energy need. in our country. Benin, Gulf of Guinea country, although with a significant coastal network powered.by potential energy from breaking waves, has experienced.a d.ficit and.a critical energy instability, marked.by recurrent power cuts and.d.sruption of the national economy. To ensure the integration of this source of renewable energy in the Benin energy mix and.sustainably red.ce the energy d.ficit in progress, this work has aimed.to stud. the d.ssipation of wave energy at the bathymetric breaking in the breakers zone of Cotonou coast. Sea cond.tions and.the statistics parameters of the breaking waves und.r perturbation effect of the seabed.were evaluated.to pred.ct the beginning of the breaking. The mod.ling is based.on the Navier-Stokes equation in which the viscosity and.the interactions between the molecules of the oceanic fluid.are neglected. The nonlinear wave d.spersion relation is also used. The results obtained.for this purpose showed.that water particles have an almost parabolic motion d.ring their fall;their velocity is higher than those of the early breaking. In this area, the waves d.ssipate about 80% of their energy: it generates turbulence which lead. to a strong setting in motion of sed.ments.
