← GeographyWhich outcome decreases the effectiveness of sediment bypassing systems installed alongside coastal barrier islands?
A)Increased wave reflection offshore
B)Insufficient pump discharge capacity✓
C)Groyne field sediment starvation
D)Elevated nearshore turbidity levels
💡 Explanation
Insufficient pump discharge capacity causes sediment accumulation at the inlet rather than bypassing it, leading to continued erosion because the *bypassing rate is reduced*. Therefore, the system fails to offset natural erosion; rather than preventing deposition downstream.
