Where do floods start?

Answer 1

Floods typically start in areas where heavy rainfall overwhelms the capacity of rivers, lakes, or drainage systems, causing water to overflow. They can also occur due to rapid snowmelt, storm surges from hurricanes, or dam failures. Additionally, urban areas with impervious surfaces can exacerbate flooding by preventing water absorption into the ground. Overall, floods can initiate in various locations depending on environmental conditions and human infrastructure.
