flood Scientific  
/ flŭd /
  1. A temporary rise of the water level, as in a river or lake or along a seacoast, resulting in its spilling over and out of its natural or artificial confines onto land that is normally dry. Floods are usually caused by excessive runoff from precipitation or snowmelt, or by coastal storm surges or other tidal phenomena.

  2. ◆ Floods are sometimes described according to their statistical occurrence. A fifty-year flood is a flood having a magnitude that is reached in a particular location on average once every fifty years. In any given year there is a two percent statistical chance of the occurrence of a fifty-year flood and a one percent chance of a hundred-year flood.


Synonym Usage

Flood, flash flood, deluge, freshet, inundation refer to the overflowing of normally dry areas, often after heavy rains. Flood is usually applied to the overflow of a great body of water, as, for example, a river, although it may refer to any water that overflows an area: a flood along the river; a flood in a basement. A flash flood is one that comes so suddenly that no preparation can be made against it; it is usually destructive, but begins almost at once to subside: a flash flood caused by a downpour. Deluge suggests a great downpouring of water, sometimes with destruction: The rain came down in a deluge. Freshet suggests a small, quick overflow such as that caused by heavy rains: a freshet in an abandoned watercourse. Inundation, a literary word, suggests the covering of a great area of land by water: the inundation of thousands of acres.

Etymology

Origin of flood

First recorded before 900; Middle English noun flod, Old English flōd; cognate with Gothic flōdus, Old High German fluot ( German Flut )

Explanation

A flood is an enormous amount of water. If the street is full of water, it's flooded. Too much of anything can also be called a flood. Whenever it rains and rains and rains, there's the danger of a flood, a type of disaster where water is out of control. Because a flood is so powerful, people use the word when overwhelmed by other things. A top college graduate could be flooded with job offers — that's a good kind of flood. People can also be flooded with emotion. Words with similar meanings are deluge and overflow. Too much — or just a lot — of anything can seem like a flood.
