Modelação da Agitação Marítima

Objectives

Introduce the ocean-atmosphere interaction and describe the main features of the oceans. Describe the linear theory of gravity waves and wave systems including how it can be generated in experimental model basins. Supply the mathematical tools to understand and describe the variability of the irregular sea states. Understand the dynamics of the wave measuring equipment and wave energy converters.
