<br />draft 3/20/98 <br /> <br />Illustrations <br /> <br />1. Diagrammatic section across a stream channel showing a flood stage and various paleoflood <br />features used as paleostage indicators (Modified from Baker, 1987). <br /> <br />2. Photographs of Spring Creek near Fort Collins, Colorado, for flood of July 28, 1997: a.) upstream <br /> <br /> <br />view of a bouldery-flood deposits (new PSI); and b.) view toward fine-grained deposits (new SWDs) <br /> <br /> <br />along the channel margin showing flood debris and unbent grass marking maximum flood height <br /> <br /> <br />(HWM). <br /> <br />3. Cross section of Spring Creek near Fort Collins, Colorado, for flood of July 28, 1997. The top of <br />the bouldery-flood deposit (new PSI) is slightly higher than, and fine-grained sediments (new SWDs) <br />equal to, the HWMs. <br /> <br />4. Summary of difference between the elevation of paleostage indicators (pSIs and SWDs) and high- <br /> <br /> <br />water marks (HWMs) and: a.) flood depth; summary of percent difference of PSI-HWMs and b.) <br /> <br /> <br />flood depth; c.) water-surface slope; d.) maximum particle size in the flood deposit; e. peak <br /> <br /> <br />discharge; and f.) flood recurrence interval for recent floods. <br /> <br />15 <br />
