Answer:
1. Jetty: Hard structure Built Perpendicular to the Shore, Can cause sand build-up on up drift side of the structure
2. Beach Nourishment: Brings in more sand to replace erosion.
3. Seawall: Hard structure that also provides flood protection, Prevents erosion by directing waves back to the ocean
Explanation:
Jetty is a hard and long structure that constructs of wood or concrete near the coastline, perpendicular to the shore that protects it from tides and currents which helps in preventing erosion. It can lead to build-up of sand on updrift side.
Beach nourishment is the process that replaces the sand or land that lost due to erosion and relensihsh the infrastructure of the coastline and protects the people and beach.
Seawall is also a hard provides protection from erosion by preventing the flood and pushes back the currents and tides to the ocean.
