How are jetties and groins similar in how they manage beach erosion

Jetties and groins are both coastal structures designed to manage beach erosion by trapping sand and other sediments. They both interrupt the natural flow of water and sediment along the coast, causing sediment to accumulate on one side of the structure. This accumulation helps to build up and stabilize the shoreline, reducing erosion and protecting coastal properties.

Both jetties and groins can also create new beaches by trapping sand and sediment in certain areas, which can help to counteract the effects of erosion. Additionally, both structures can help to maintain navigational channels and protect harbors from sediment accumulation.

Overall, jetties and groins are similar in that they help to manage beach erosion by trapping sediment and redistributing it along the coast, ultimately helping to protect coastal areas from the effects of erosion.
