Aallonnopeuksista, also known as wave breaking, is a natural phenomenon that occurs in the ocean when the height of the waves exceeds a certain threshold relative to the water depth. This process is crucial for the energy transfer from wind to water and plays a significant role in shaping coastal landscapes. There are several types of wave breaking, each with distinct characteristics and impacts.

Plunging breakers are the most common type, occurring when the wave height is about 1.3 times the water depth. These breakers are characterized by a steep front face and a curling, plunging motion as they collapse onto the shore. Plunging breakers are powerful and can generate significant turbulence and spray.

Spilling breakers occur when the wave height is about 1.7 times the water depth. These breakers have a gentle, sloping front face and a smooth, rolling motion as they break. Spilling breakers are less turbulent and generate less spray than plunging breakers.

Surging breakers occur when the wave height is about 2.5 times the water depth. These breakers have a very gentle slope and a smooth, rolling motion as they break. Surging breakers are the least turbulent and generate the least amount of spray.

Wave breaking is a dynamic process that is influenced by a variety of factors, including wind speed, water depth, and the shape of the coastline. Understanding wave breaking is essential for coastal management, navigation, and recreation.
