Building breakwaters in the ocean will reduce the wave erosion.
Waves destroy cliff and coastline deposits. The silt in ocean water functions similarly to sandpaper. They degrade the beach over time. The larger the waves and the more silt they transport, the greater the erosion.
Structures built on the beach (seawalls, groynes, breakwaters/artificial headlands) or further offshore are used in hard structural/engineering alternatives (offshore breakwaters). These strategies alter coastal processes in order to slow or stop coastal erosion.
Breakwaters are offshore obstacles that protect a portion of the shoreline. They serve as a wave barrier, preventing erosion and allowing the beach to expand. Wave energy dissipation permits material transported by longshore currents to be deposited behind the breakwater. This safeguards the beach.
Therefore, the correct option is to build breakwaters in the ocean.
