← GeographyWhich outcome on a coast dominated by longshore drift results after constructing a new, large breakwater?
A)Increased erosion downdrift close to inlets✓
B)Decreased tidal range along the coast
C)Uniform sediment distribution across coast
D)Enhanced biodiversity within lagoon systems
💡 Explanation
Increased erosion happens downdrift because the breakwater blocks sediment transport via longshore drift, starving areas further down; therefore, erosion dominates rather than sediment deposition downdrift occurs because inlets become sediment traps.
