Question

Quizplus · Accepted Answer

Structures like jetties, groins, and breakwaters are not permanent solutions to beach erosion. They may decrease the rate of beach erosion temporarily, but they also create problems such as beach narrowing, loss of sand on the downcoast side, and change in the natural beach processes. Therefore, they should be used in conjunction with other erosion-control techniques such as beach nourishment. They do not have any added benefits of allowing organic coasts to develop, which is a natural process.
