Erosion can primarily lead to lower beach elevations. As waves and currents remove sand and sediment from the beach, the overall height and volume of the beach can diminish, resulting in a lower elevation. In contrast, erosion typically does not create wider beaches or increased sand on beaches; those conditions are more commonly associated with sediment deposition rather than erosion. Higher beach elevations can also be affected by processes such as deposition or beach nourishment, not erosion. Thus, the main effect of erosion on a beach is the reduction of its elevation.
