Levees are raised structures built along the edges of rivers or lakes to prevent flooding. They act like walls, holding back water during heavy rains or when snow melts. By keeping water contained, levees help protect homes, farms, and roads from being submerged. These structures can be made from earth, concrete, or other materials, and they are often part of a larger flood control system. In some areas, engineers regularly inspect and maintain levees to ensure they remain strong and effective. When levees fail, it can lead to significant damage and loss, highlighting their importance in flood management.
