What practice involves adding sand to the beach to replace sediments lost to erosion?

• A. Longshore Drift
• B. Beach Replenishment
• C. Rip Currents
• D. Barrier Islands

Answer: (B)

Beach replenishment is the practice of adding sand to replace sediments lost to erosion. By sourcing sand from offshore borrow areas and spreading it along the beach, the shoreline width and dune protection are restored, which helps reduce wave energy reaching inland areas and supports habitat and recreation. It’s a remediation measure that can be effective but is usually temporary and requires ongoing maintenance, with considerations like sand compatibility and environmental impact.

Longshore drift is the process that moves sediment along the coast with waves, not a method of adding sand. Rip currents are strong seaward flows that pull water offshore, posing a danger rather than being a sediment-management technique. Barrier islands are protective landforms, not a practice to replenish a beach.
