Which outcome occurs when longshore drift is interrupted by a groin?

💡 Explanation

Erosion increases down-drift of the groin because sediment transport is reduced through sediment starvation downstream; therefore, erosion increases on the down-drift side, rather than accumulating sediment evenly without impediment.
