Adding new sand helps to prevent sinkholes from forming along the coast. A safer environment for the public is created at the beach.īeach erosion produces numerous safety issues over time that may impact how the public uses the space. When a renourishment project is successful, it can promote higher sustainability levels.ģ. Adding sand reduces the physical hazards that can be found at the beach, create safe habitats for marine life, and reduce the risk of toxins spreading along the coast. That means businesses located at the shore of more revenue earning opportunities available to them. When a beach is wider, it is usable by more people. It widens the beach to create more usage opportunities. This project keeps the environment stable, which means it continues to support the economy in a variety of ways.Ģ. Over time, if tidal surges are repetitively strong, the shore ecosystem could eventually collapse. Even during strong surges, the sediment reduces the risk of a beach structure suffering a catastrophic incident. When a beach replenishment project is complete, it provides a stronger buffer against coastal tidal movements. Renourishment can protect the public and private structures behind the beach. List of the Pros of Beach Renourishmentġ. That is why these beach renourishment pros and cons must be carefully evaluated before beginning this type of project. Some beaches do not benefit as much from this type of project as others because of their location, the amount of submerged sand available, and other factors that may be present geographically. It is now used around the world as a way to protect shorelines because of the effectiveness of this process. The first beach renourishment project in the United States was completed at Coney Island in 1923. The new sand interacts with the waves in the surf zone to reduce the impact of very high tides, storm surges, and even tsunamis. By creating a wider beach with new sand, it becomes possible to prevent future damage to coastal structures. Beach renourishment is a project which replaces sand (or other sediment) that is lost through erosion, longshore drift, or other reasons.
