Flood walls are structures designed to protect areas from rising water levels during floods. They are typically made of concrete or earth and are built along rivers, lakes, or coastal areas to prevent water from spilling into nearby land. Flood walls can vary in height and length, depending on the specific needs of the area they protect. These walls work by redirecting water away from vulnerable regions, helping to safeguard homes, businesses, and infrastructure. In some cases, flood walls are part of larger flood control systems that may include levees, dams, and drainage systems to manage water flow effectively.
