Floods occur when an area receives too much rain or water, causing the water levels to rise over the land. They can be caused by heavy rainfall or other factors. Floods affect the environment, economy, and people. They pollute water, destroy businesses and infrastructure, and can kill people or force them to evacuate damaged homes. Many regions around the world experience frequent flooding, including parts of Brazil, North and South America, Europe, Australia, Asia, and Mexico. While floods are a natural disaster, their impacts are exacerbated by factors like increased rainfall and lack of adequate flood control measures. Prevention methods include building more canals, dams, and channels to redirect excess water.
