You’re absolutely correct that in this area, his dynamic berm fits the hydrology, and that these are not good solutions in other places. Examples: - If the coast is too steep, the rocks won’t reach an equilibrium, and you now just have erosion of rock before your erosion of sand. - If egg-laying sea/coastal life needs sand like sea turtles or some birds - Surfers and tourism (as you mentioned) - If the sand erosion is acting as a source for something downstream; stopping the sand movement will cause erosion in that area (nourishing the beach with sand would probably be a better fit) (Edited formatting)
