Relation between peak discharge and drainage area for streams in eastern Colorado. Data are <br />stratified based on high or low topographic relief in a basin. High-topographic relief basins <br />(more than about 300 feet of relief in about three miles or less) include Cherry Creek (CC), <br />Box Elder Creek (BE), Kiowa Creek, and other Palmer Divide eO) streams such as East Plum <br />and Bijou Creeks. Envelope curves for maximum floods and PMF values (Bullard, 1986; U.S. <br />Army Corps of Engineers, written commun., 1997) for eastern Colorado also are shown. <br />Floods in low-topographic relief basins (Low TR) throughout eestern Colorado plot on or below <br />the Cherry Creek basin envelope curve. <br /> <br />9000 <br /> <br />East <br /> <br />West Box Elder Cr <br /> ~ <br /> i~' u <br />loothills <br /> ~ <br />~ ,g. <br /> CD <br /> : ! <br /> ~:! == <br /> <br />~ <br />,~ <br />~ <br />:g. <br />", <br />I.lJ <br /> <br />- <br />C1l <br />C1l <br />- <br /> <br />8000 <br /> <br />c: <br />o <br /> <br /> <br />. <br /> <br />~ <br />, <br /> <br />- <br />ell <br />> <br />C1l <br />W <br /> <br /> ~ ~ <br /> UU ~ <br /> U <br />,., ,.,~ <br />~ - ~ ~ <br />~ <br /><D ~ 0 ~ <br />.s:: <D- o <br />() <'3'" ;;; <br />== w== <br /> <br />D... tt... .~O....III...I. <br /> <br />7000 ~ <br />u <br /> E <br /> ~ <br /> 0: <br /> w <br />6000 <br />0 <br /> <br />10 20 30 40 <br />Distance, miles <br /> <br />50 <br /> <br />60 <br /> <br />5.
