Coastal Erosion: The process by which coastlines are eroded due to wave action, currents, and tidal forces, leading to loss of land and changes in coastal morphology.

Sediment Transport: The movement of solid particles, typically sand or gravel, along the coastline due to natural forces such as waves and currents, influencing the formation of various coastal landforms.

Beach Nourishment: A coastal management technique that involves adding sand or sediment to a beach to combat erosion and restore its natural shape and function.
