Which risk increases for coastal communities when extensive seawall construction prevents sediment deposition?

💡 Explanation

Accelerated erosion of beaches downdrift occurs because the coastal system's sediment transport is interrupted by the seawall; hindering longshore drift means sediment isn't replenished, therefore areas erode rather than accrete.
