Flood Intelligence
Flooding is the most common natural disaster in the United States. It can result from heavy rainfall, storm surge, snowmelt, or the failure of water control structures. Flash floods can develop within minutes, while river floods may build over days or weeks. Flooding causes more deaths and property damage than any other type of natural hazard.
