<br />GLUSSAR'Y OF TERMS <br /> <br />I <br />I <br /> <br />Bearing <br />The horizontal angulilr measurement cf a line, in dogreos, east or <br />westofanorth-southreterence line. <br /> <br />FloodSt<lge <br />The stage cr elevation at which overflow of the natural banks of a <br />stream or body of water bogins in the roach or area in which the eleva- <br />tion is measured. <br /> <br />Flood <br /> <br />Headless <br />The effect of obstructions. such as narrow bridge openings or build- <br />ings that limit the aree through Which water must flow, raising the <br />surfllce of the water upstream from the obstruction. <br /> <br />An overflow on lands not norfl'"lly covered byw<lter and that are <br />usedorusableby~n. Floods have two essential charactoristics: <br />n.e inundation 01 land is temporary; and tho land is <Idjllcent to and <br />inundated by overflow from a river or stream or an ocean, lake or <br />other body of standing water. <br />Normally a flood is considered as any temporary rise in stream <br />flow or stage, but not the pondlngof surface wator, that results In <br />significant adverse effocts in the vicinity. Adverse effects may <br />inclUde d<lmages from overflow of land areas, temporary backwater <br />effects in sewers and local drainage channals, creation of unsanitary <br />conditions or other unfavorable situations by deposition of materials <br />in stream channels during flood recessions, rise 01 ground wllter coin- <br />cident with increase~ stream flow, and ot~er problem~. <br /> <br />Intermediate Regional Flood <br />A flood h"vinga one percent probability of occurrence in any year <br />or an average frequency of occurrence In the order of OnCe in 100 years. <br />The Ilood may occur in "ny year. It is based on statisticlll analyses <br />01 stream flow recordS and analyses of rllinfall and runoff charllcteristics <br />in the general region of the waterShed. <br /> <br />LeftSenk <br /> <br />The b"n~ on the ".ft s ide of " ri ver, STraam or water course, look~ <br />ingdownstream. <br /> <br />FloodCrcst <br />The maximum stage or elevation reached by the waters 01 a tlooo <br />at a given location. <br /> <br />RelerencePoint <br />A numbered point identifying a specific location for correlating <br />the data Shown In various forms throughout the report. <br /> <br />Flood Plain <br />The relatively flat area or low lends adjoining the channel of <br />" river, stream or wllter courSe or ocean, la~e or other body of stand~ <br />ing water, Which has been or may be covered by floodwater. <br /> <br />Right Bank <br />The bank on the right side of a river, stream or water course, <br />looking downstream. <br /> <br />Flood Profile <br />A graph showing the relationship of water surface elevation to <br />location, the latter generally expressod as distance above ""0uth lor <br />as'trellmot...ater flo.<ing in i1nopan channel.
