Wave action refers to the movement of water caused by the energy transferred from wind to the surface of the ocean or other bodies of water. This energy creates waves that can vary in size and strength, depending on factors like wind speed, duration, and the distance over which the wind blows. As waves approach the shore, they interact with the seabed, causing them to slow down and increase in height. This process can lead to breaking waves, which are responsible for shaping coastlines and influencing sediment transport. Understanding wave action is essential for coastal management and navigation.
