Flood barriers are structures designed to prevent or reduce the impact of flooding in vulnerable areas. They can be made from various materials, including concrete, steel, and inflatable fabrics. These barriers are often deployed in response to rising water levels, protecting homes, businesses, and infrastructure from damage. There are different types of flood barriers, such as levees, flood walls, and temporary barriers. Levees are earthen embankments built along rivers, while flood walls are solid structures that can withstand water pressure. Temporary barriers can be quickly set up during emergencies, providing immediate protection against floodwaters.
