Flood defenses are structures and systems designed to protect areas from the damaging effects of flooding. These can include levees, which are raised banks along rivers, and dams, which hold back water. Other methods involve flood walls and stormwater drainage systems that help redirect excess water away from populated areas. In addition to physical structures, flood defenses also include natural solutions like restoring wetlands and forests. These natural barriers can absorb excess rainwater and reduce the speed of floodwaters. Together, these strategies help keep communities safe and minimize the impact of heavy rainfall and rising water levels.
