Coastal Defense Systems are structures and strategies designed to protect coastlines from erosion, flooding, and storm surges. These systems can include natural barriers like dunes and wetlands, as well as man-made structures such as sea walls, breakwaters, and groins. Their primary goal is to safeguard coastal communities and infrastructure from the impacts of severe weather and rising sea levels. In addition to physical barriers, Coastal Defense Systems often involve planning and management practices that promote sustainable coastal development. This can include restoring natural habitats and implementing zoning regulations to minimize damage from coastal hazards. Effective coastal defense is essential for preserving ecosystems and ensuring the safety of coastal populations.
