Here is your answer!
Localized flooding may be caused or exacerbated by drainage obstructions such as landslides, ice, debris, or beaver dams.
Slow-rising floods most commonly occur in large rivers with large catchment areas.
The increase in flow may be the
result of sustained rainfall, rapid snow melt, monsoons, or tropical cyclones.
Floods are one of the leading causes of death from natural disasters in the United States. Over 200 flood-related fatalities are reported each year with over half being vehicle-related when people try to drive through floodwaters. Floods can damage and devastate homes and farms, displace families as well as pets and livestock, damage crops, and disrupt agriculture processing and business.
Flood situations are variable and can occur as a result of spring snowmelt, severe thunderstorms, prolonged rains, inadequate drainage or failure of levees and dams. The impact can be local affecting a neighborhood or community, or very large, affecting entire river basins and multiple states. Some develop slowly – allowing time to prepare and evacuate – while others (e.g., flash floods) can develop quickly, even within minutes.
While flood situations cannot be entirely prevented, steps can be taken to prevent or minimize injury and loss and speed the recovery process. The following resources will help you prepare your family, home and farm, animals and business for flood situations.
