Beach Erosion. Beach erosion occurs when waves and currents remove sand from the beach system. The loss of sand causes the beach to become narrower and lower in elevation (Figure 1).Storm waves carry the sand offshore, depositing and storing the sediment in large sandbars.each erosion occurs when waves and currents remove sand from the beach system. The loss of sand causes the beach to become narrower and lower in elevation (Figure 1).
If sediment is not added to a beach or coastline as quickly as it is removed, the coastline shrinks. Eventually such areas disappear entirely. Human development also causes coastal erosion, as structures such as bridges and levees change the flow characteristics near the coast.
