Beach barrier is an artificial wall or barrier that is built along the coast of a beach, built to protect the beach from erosion and reduce the impact of waves and rising sea levels.

Beach barriers can be made from a variety of materials, including concrete, steel, timber, and plastic. Concrete barriers are often used in coastal areas to protect beach areas from erosion. They are typically built using concrete blocks and can be either single- or multiple-section walls. Steel barriers are typically used in areas that require higher strength and can be either solid or mesh. Timber barriers are suitable for areas where a more natural look is desired. Plastic barriers are often used in areas where a lightweight and more cost-effective solution is needed.

Beach barriers can be used for a variety of purposes, including coastal defense, coastal protection, and recreation. In coastal defense, barriers are used to protect the beach from the impact of waves and rising sea levels. In coastal protection, barriers are used to prevent beach erosion by breaking the force of incoming waves. In recreation, barriers are used to create a more comfortable beach environment, such as providing shade, noise and visual barriers.

Beach barriers can also be used to manage and control beach access. For example, beach barriers can be used to control the flow of people, vehicles, and other objects onto a beach or public space. They may also be used to designate certain areas as private or off-limits.

In summary, beach barriers are artificial walls or barriers that are built to protect beaches from erosion and reduce the impact of waves and rising sea levels. They can be made from a variety of materials and used for a variety of purposes, including coastal defense, coastal protection, recreation, and access control.
