Coastal protection systems are structures designed to safeguard shorelines from erosion, flooding, and storm surges. These systems can include sea walls, breakwaters, and dunes, which help absorb wave energy and reduce the impact of high tides. By stabilizing the coastline, they protect both natural habitats and human developments. In addition to physical structures, coastal protection can involve beach nourishment, where sand is added to beaches to combat erosion. These systems are essential for maintaining the health of coastal ecosystems and ensuring the safety of communities living near the coast.
