Fast Facts On Floods
Floods are one
of the most common hazards in the United States. Flood effects can
be local, impacting a neighborhood or community,
or very large, affecting entire river basins and multiple
states.
However, all floods
are not alike. Some floods develop slowly, sometimes over a period
of days. But flash floods can develop quickly, sometimes in just a
few minutes and without any visible signs of rain. Flash floods
often have a dangerous wall of roaring water that carries rocks,
mud, and other debris and can sweep away most things in its path.
Overland flooding occurs outside a defined river or stream, such as
when a levee is breached, but still can be destructive. Flooding can
also occur when a dam breaks, producing effects similar to flash
floods.
Be aware of flood
hazards no matter where you live, but especially if you live in a
low-lying area, near water or downstream from a dam. Even very small
streams, gullies, creeks, culverts, dry streambeds, or low-lying
ground that appear harmless in dry weather can flood. Every state is
at risk from this hazard.
