Beach nourishment is a coastal management technique used to combat beach erosion. It involves adding sand or sediment to a beach to restore its width and elevation. This process helps protect coastal properties and ecosystems from the impacts of waves and storms. The materials used in beach nourishment are typically sourced from nearby offshore areas or rivers. The added sand blends with the existing beach, creating a wider area for recreation and wildlife. While effective, beach nourishment requires regular maintenance and monitoring to ensure its long-term success and sustainability.
