What conditions does a flood happen?

Answer 1

Flooding typically occurs when there is excessive rainfall over a short period, causing rivers, lakes, or reservoirs to overflow. Other conditions that can contribute to flooding include rapid snowmelt, storm surges from hurricanes or tropical storms, and the failure of dams or levees. Urbanization can also exacerbate flooding, as impervious surfaces like roads and buildings prevent water absorption into the ground. Additionally, topography and soil saturation levels play significant roles in flood risk.
