Quizplus · Accepted Answer

Beach nourishment is expensive because it requires large amounts of sand to be brought in from elsewhere and placed on the beach, while hard stabilization structures such as groynes or breakwaters are usually made of inexpensive materials like wood or concrete. Beach nourishment also needs to be repeated every few years, making it a costly ongoing process. The cost of hard stabilization is offset by its longer lifespan, which can provide protection against erosion for decades or even centuries.
