Which consequence results when a coastal jetty impedes longshore drift?

💡 Explanation

Sediment accumulates updrift of the jetty due to sediment interruption; the mechanism halting sand transport is sediment deposition. Therefore, accretion occurs on the updrift side, because rather than erosion which happens downdrift, the sediment piles up.
