Question

Quizplus · Accepted Answer

A groin is a man-made structure built perpendicular to the coastline to prevent or reduce erosion on a specific stretch of beach. When a groin is constructed, it disrupts the natural movement of sediment along the beach. Sediment that would normally continue along the beach is trapped on the upcurrent side of the groin, causing erosion, while sediment is deposited on the downcurrent side of the groin. Therefore, the best choice is D, which states that there will be deposition on the downcurrent side and erosion on the upcurrent side of the groin.
