Preventing and mitigating floods involves a combination of engineering, policy, and community engagement strategies. Infrastructure improvements, such as building levees, dams, and floodwalls, can help control water flow and protect vulnerable areas. Additionally, restoring wetlands and natural floodplains can enhance the land's ability to absorb excess water. Urban planning plays a critical role in flood prevention; implementing green spaces and permeable surfaces can reduce runoff in cities. Furthermore, communities can benefit from early warning systems and emergency preparedness plans to ensure swift action during flood events. Education and awareness campaigns can also empower residents to take proactive measures to protect themselves and their properties.
