Flood
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.
