A beach vulnerability study at Copacabana beach, Rio de Janeiro: A study into the historic, present and future morphodynamic behavior of the beach focused on the impact of storm events and subsequent recovery
Sandy beaches can be found all over the world and are on the interface between the sea and the land. Important functions of beaches are the protection of the inland to the forces of the sea and providing local opportunities in recreation. The impact of storm events on the beach is therefore an impor...
