ENERGETIC POWER ESTIMATION OF SWELLS AND ORBITAL MARINE CURRENTS IN BENIN COASTAL ZONE (GULF OF GUINEA)

The announced depletion of fossil energy resources is fueling some speculation. It therefore urgent to explore the different renewable sources available Benin. In ocean, in addition swells, there are also orbital marine currents generated by them. An advantageous solution for countries located Gulf Guinea recovery and transformation swell its into electrical energy. Swells adult waves that propagate freely at atmosphere-ocean interface. this work, based on measurements made Millenium Challenge Account (MCA-Benin) as part extension Autonomous Port Cotonou, we have shown swells Cotonou Airy or Stokes. We identified modified Boussinesq equations, proposed Peregrine 1967, theory characterizing evolution these during their formation coastal zone. variations wave parameters (height, wavelength, period, phase group velocities) characterized from shoaling zone breaking point. With results obtained agreement with experimental made, they perfectly describe amplification height show become very energetic when approach coast.
