Which consequence results when longshore drift increases sediment deposition near a harbor entrance?

💡 Explanation

Increased longshore drift causes sediment to accumulate via **littoral transport**, obstructing harbor access because the moving sediment load drops where the flow dynamics change; therefore, navigational channel siltation intensifies rather than other effects due to sediment accumulation elsewhere.
