Question

Quizplus · Accepted Answer

All of these measures (beach nourishment, groin, and seawall) are commonly used to prevent or retard shoreline erosion. Beach nourishment involves adding sand to a beach to widen it and provide additional protection against waves. A groin is a barrier constructed perpendicular to the shoreline that traps sediment and slows down the movement of waves, helping to protect the shoreline. A seawall is a vertical barrier constructed parallel to the shoreline that provides protection against wave energy by reflecting it back into the ocean. All of these measures have advantages and disadvantages, and their effectiveness depends on a number of factors, including the local climate, wave energy, sediment transport, and other factors.
