  Flood plain - Wikipedia, the free encyclopedia
In geography, a flood plain is a plain formed of sediment, typically dropped by a river.
Still, flood plains are most commonly found near the mouth of a large river, such as the Rhine, the Nile, or the Mississippi, where there are occasional floods and the river usually carries a large amount of sediment.
The flood plain during its formation is marked by meandering or anastomosing streams, ox-bow lakes and bayous, marshes or stagnant pools, and is occasionally completely covered with water.

The annual cycle of flood and farming was of great significance to many early farming cultures, most famously to the ancient Egyptians of the Nile river and to the Mesopotamians of the Tigris and Euphrates rivers.
Floods happen when soil and vegetation cannot absorb all the water ; water then runs off the land in quantities that cannot be carried in stream channels or kept in natural ponds or man-made reservoirs.

 Flood prevention: the earthmover approach
Rather than worrying about floods like the 1993 edition, which only come every 100 years or so, Galat says it's more sensible to examine what the effects of "messing with the river" are on the floods that occur every couple of years or so.
The height of these floods, he says, is profoundly increased by building levees, wetland loss, deforestation, stream channelization and changes in land use in the watershed.
The absence of a flood is a disturbance of a river."

Flood frequencies, such as the "100-year flood," are determined by plotting a graph of the size of all known floods for an area and determining how often floods of a particular size occur.
Another way of expressing the flood frequency is the chance of occurrence in a given year, which is the percentage of the probability of flooding each year.

But environmentalists argued it could change the way flood areas are developed in the future on waterways here and across the country.

Since a 1993 flood in St. Louis, when the Mississippi River lapped at the steps of the Gateway Arch, more than 14,000 acres of flood plain have been developed.

That parallels the situation in New Orleans, which suffered catastrophic flooding in August when levees failed in the wake of Hurricane Katrina.
