Which mechanism causes increased sediment deposit behind a newly constructed coastal breakwater?

💡 Explanation

Reduced coastal currents lead to sediment deposition because longshore drift, the primary erosion and transport mechanism, diminishes within the breakwater's sheltered zone; therefore deposition occurs rather than erosion because the wave energy reduction limits sediment transport.
