methodologies used by state and federal agencies in performing detailed analyses, except that <br />there is no balancing of energy from one cross - section to the next. <br />The three surveyed cross - sections, the two surveyed cross - sections transferred to reaches other <br />than the reach where they were surveyed, and the three cross - sections that were hybrids of map <br />cross - sections and field data are graphically represented in Figures 7A -7H. Example rating <br />curves were prepared for the three field- surveyed cross - sections. They are presented in Plates <br />8 -11, after the floodplain maps. <br />' 4.5 Delineating Flood Boundaries <br />The calculated flood depths for the various stream reaches were first plotted on the quadrangle <br />' maps at the cross - section locations. The resulting floodplain widths were compared to the <br />floodplain widths on the cross - section plots. The floodplain boundaries between the cross- <br />' sections were then approximated by delineating flood depth contours and interpreting the <br />relationship between those flood depth contours and the ground contours. Consideration was <br />given to the slope within each reach. The finalized information was displayed on the USGS 7.5' <br />' quadrangle maps (scale of 1" = 2,000'). A table identifying the quadrangle maps used in each <br />plate and the map scale is given in Figure 8. A map showing the location of each floodplain <br />map plate is shown in Figure 9, and the floodplain maps are shown in Plates 1 -7. <br />n <br />0 <br />0 <br />17 <br />
