Özet:
Knowledge of sea states is an essential factor in ensuring economic, clean and sustainable exploitation of coastal and offshore areas. This thesis presents a detailed assessment of wave energy along the Algerian coast, covering both the constructive and destructive aspects. Two methodological approaches have been developed to address two major issues of the day. The first problem is the significant growth in electricity consumption in Algeria, combined with the problems of global warming, marine and atmospheric pollution from thermal power plants installed along the Algerian coast, and the need to preserve fuel energy resources. The Algerian Ministry of Energy and Mines (MEM) has developed a national program aimed at achieving a 40% share of renewable energies in electricity production by 2030. As part of this program, several potential zones based on solar, wind and geothermal energy resources have been identified. This research has shown that significant solar and wind energy resources are located in the southern Saharan part of the country. However, according to statistics from the national electricity company (Sonelgaz), over 40% of electricity is consumed by the coastal provinces, which cover 1.8% of the country. As a result, and in view of the ongoing development of wave energy recuperators in recent years, wave energy, presented in the condensed form of wind power, constitutes an essential source of renewable energy that can be exploited in these high-consumption coastal areas. Assessing the propagation of marine energy is a very important task, not only for its deployment but also for its damaging role in coastal areas, which poses a considerable risk on stormy days. This destructive aspect of wave energies represents the second problem investigated in this thesis. The various studies and coastal developments linked to different marine activities require a detailed study of the propagation of storm wave energies along the coast, on the one hand, to ensure the economic design and sustainable reinforcement of port and coastal protection infrastructures, and on the other hand to identify vulnerable coastal zones exposed to high natural risks.
