How long do offshore breakwaters last?
Offshore breakwaters typically have a lifespan of 20 to 50 years, depending on various factors such as design, materials used, environmental conditions, and maintenance practices. Regular inspections and maintenance can extend their longevity, while harsh weather and erosion can significantly shorten it. Proper design and construction play crucial roles in ensuring their durability against wave action and sediment movement.

What are the four types of coastal defenses?
The four main types of coastal defenses are seawalls, breakwaters, groynes, and beach nourishment. Seawalls are vertical structures built parallel to the shore to prevent erosion, breakwaters are offshore barriers that protect the coast from wave action, groynes are perpendicular structures that trap sediment to build up beaches, and beach nourishment involves adding sand or sediment to a beach to widen it and protect it from erosion.
How does breakwaters affect longshore current?
Breakwaters can disrupt longshore currents by reducing their energy and altering their direction. Breakwaters can create calm areas behind them that lead to changes in sediment transport and can result in sediment accumulation or erosion. In some cases, breakwaters have been found to mitigate the effects of longshore currents by protecting coastlines from erosion.
