← GeographyWhich consequence results when a coastal jetty impedes longshore drift?
A)Accretion on the jetty's updrift side✓
B)Increased offshore sediment transport
C)Decreased coastal erosion rates overall
D)Formation of a symmetrical delta
💡 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.
