Description: The swell refers to a series of mechanical waves that propagate along the surface of the sea, primarily generated by the action of the wind on the water. These waves can vary in size, shape, and energy, depending on factors such as wind speed, the duration of its action, and the distance over which it blows. Swell is a natural phenomenon that not only affects the aesthetics of the marine landscape but also has a significant impact on navigation, fishing, and recreational activities at sea. Waves can be classified into different types, such as wind waves, storm waves, and swell, each with unique characteristics. Additionally, swell plays a crucial role in coastal erosion and beach formation, as the movement of water can transport sediments and modify the geography of coastlines. In the context of ports, swell is a determining factor that influences the safety of maritime operations, affecting the arrival and departure of vessels, as well as the loading and unloading of goods. Therefore, understanding swell is essential for the planning and management of port activities, as well as for the protection of coastal infrastructure.
