Both jetties and seawalls are hard structures that reduce erosion caused by waves by breaking up wave energy and protecting the shoreline.

I apologize for the oversight in my previous responses. Jetties are structures built perpendicular to the shore to control the movement of sand and maintain navigation channels, while seawalls are vertical structures built along the shoreline to protect properties from waves and erosion.
Jetties help manage beach erosion by trapping sand and sediment, reducing the amount of sediment that would otherwise move down the beach and contribute to erosion. Seawalls, on the other hand, absorb and reflect wave energy, protecting the shore from erosion.
In summary:
- Jetties bring sand to the beach from offshore and help control sediment movement.
- Seawalls provide flood protection in the event of high waves and reduce erosion by absorbing and reflecting wave energy.
