<br />
<br />An area in and adjacent to a stream which is subject
<br />to flooding as a result: of the occurrence of a 1% Chance
<br />Flood.' Thus it is so adverse to past, current, or fore-
<br />seeable construction or land use as to constitute a
<br />significant hao:ard to public health and safety or to
<br />property.

<br />
<br />A graph showing the relationship of water surface
<br />elevation to location, the latter generally expressed
<br />as a distance above the mouth for a stream of water
<br />flowing in an open channel. It is generally drawn to
<br />show the surface elevation for the crest of a specific
<br />flood, but may be prepared for the conditions at a
<br />given time or stage.
<br />
<br />The stage Or elevation at whieh overflow of the natural
<br />banks of a stream or body of >rater begins in the reach
<br />or area in which the elevation is measured.
<br />
<br />The distance bet"eE!n the normal or design water level
<br />and the top of a dike or conduit which is left to allow
<br />for wave action and floating debris.
<br />
<br />The bank on the left side of a river, stream, or water
<br />course as the observer looks downstream.
<br />
<br />A statistical distribution used in flood frequency
<br />analysis; which is described by three parameters: ( I)
<br />the mean, (2) the standard deviation, (3) the coeffi-
<br />cient of skewness of the logarithms; of the sample
<br />observations.
<br />The winding of a stream ehann,!!l.
<br />
<br />Any natural or manmade object existing in, along, across,
<br />or projecting into any channel, water course, or regula-
<br />tory flood hazard area which may impede, retard, or
<br />change the depth or the direction of flow of water either
<br />by itself or by catching or collecting debris carried
<br />by such water" or that is placed where the flow of the
<br />water might carry the same downstream to the damage of
<br />life or property.
<br />
<br />The largest v'llue of streamflow attained by a flood,
<br />usually reported in units of cubic feet per second (cfs).
<br />
<br />The discharge of >rater, in liguid or solid state, out
<br />of the atmosphere, generally upon a land or water sur-
<br />face. Precipitation includes rainfall, snow, hail, and
<br />sleet, and is ther"fore a more geneTal term than rainfall.
