Which outcome reduces sand supply to beaches due to offshore breakwater construction?

💡 Explanation

Increased downdrift erosion results because interruption of longshore drift prevents sediment replenishment; therefore, beaches erode further rather than accreting sediment, involving longshore transport limitations instead of wave dynamics variations.
