Do floods always occur along rivers?
Flooding along rivers is a natural and inevitable part of life. Some floods occur seasonally when winter or spring rains, coupled with melting snows, fill river basins with too much water, too quickly. Torrential rains from decaying hurricanes or tropical systems can also produce river flooding.
Where do river floods occur the most?
River floodplains and coastal areas are the most susceptible to flooding, however, it is possible for flooding to occur in areas with unusually long periods of heavy rainfall.

In other words, the chances that a river will flow as high as the 100-year flood stage this year is 1 in 100. Statistically, each year begins with the same 1-percent chance that a 100-year event will occur.
Which state has the most floods?
1. Florida – Florida faces the largest coastal flooding threat in the country. About 3.5 million people are at risk of coastal flooding across Florida’s 638 square mile coast and 1.5 million people are at risk of inland flooding.
What types of conditions can cause spring floods?
During the early spring, frozen land prevents melting snow or rainfall from seeping into the ground. The water then runs off the surface and flows into lakes, streams, and rivers, causing excess water to spill over their banks. Add seasonal storms to the mix, and the result is often severe spring flooding.

Why was there so much flooding in the fall?
This quickly melted the snow, and the frozen ground was not able to absorb any meaningful amount, which led to unprecedented runoff into local streams and rivers. Saturated soils, combined with elevated river flow from the previous fall, led to severe, widespread flooding across the Eastern U.S.
