How do both jetties and seawalls help manage beach erosion?(1 point) Responses Both bring sand to the beach from offshore. Both bring sand to the beach from offshore. Both provide flood protection in the event of high waves. Both provide flood protection in the event of high waves. Both use plants to help keep sand on the beach. Both use plants to help keep sand on the beach. Both are hard structures that reduce erosion caused by waves.

Both jetties and seawalls are hard structures that are built along the shoreline to reduce erosion caused by waves. Jetties are typically built perpendicular to the shoreline and help trap sand and sediment, preventing it from being washed away by currents. Seawalls are vertical structures built along the shoreline to absorb and deflect the energy of incoming waves, protecting the beach from erosion. Both jetties and seawalls help manage beach erosion by stabilizing the shoreline and protecting it from the impacts of wave action.
