What happens when wave base intersects the seafloor?

When wave base intersects the seafloor, it marks the depth at which wave motion is negligible, typically around half the wavelength of surface waves. Below this depth, sediment and other materials are less affected by wave action, leading to a more stable environment for marine life. Additionally, the interaction can influence sediment transport and the formation of underwater features, such as sandbars and reefs, as wave energy dissipates upon reaching the seafloor.
