Destructive waves are high-energy sea waves that play a key role in coastal erosion. These waves are characterised by a high frequency and height, with powerful backwash and weak swash. As a result, they remove sediment from the beach, transporting it back out to sea, leading to the erosion of coastlines. Destructive waves are typically formed by strong winds and storms, hitting the shore with immense force and steep gradients. Understanding these waves helps students grasp how coastal landscapes change over time and the impact of natural forces on the environment.
