<br />obtained. In this form, it is possible to use ARC functions to create the point or <br />coordinate coverages necessary for analysis. <br /> <br />Analysis <br />Cross Section Plots <br />The cross-section plots reveal the channel behavior during the passage of <br />the flood. Cross-sections generally fall into one of three categories. These are <br />scour I fill, filll scour and no change. Some cross sections exhibit combinations of <br />these responses. The bed elevations and presence of dunes are also evident in the <br />cross-section plots. <br />The cross-section data also provide the information necessary to produce <br />water surface and bed profiles. These are included in appendices A and C. <br /> <br />RESULTS TO DATE <br /> <br />Results for the cross- sections and the topographic maps are presented <br />here. All cross-section surveys have been processed, plotted and overlayed in <br />relation to previous surveys (Fig. 6 - 8, 13, App B and D). They provide <br />information on year-to-year changes, mechanisms of geomorphic change and <br />bed evolution during the flood year. Refer to FIGURES 2 and 3 to determine the <br />location in the study reaches of the cross-sections discussed below. When <br />viewing the cross sections, bear in mind that cross sections were not surveyed at <br />the peak of the 1996 hydrograph. Subsequently, the highest stage shown in 1996 <br />data is approximately 1 meter lower than the maximum stage reached during <br />the 1996 flood. <br /> <br />Ouray <br />Cross Sections <br />Smaller, low elevation bar complexes were deposited at higher elevations <br />by the 1996 flood than the 1993 flood of similar magnitude (Figs. 6d and 8 a). <br />Cross-section 5 at Ouray spans an emergent sandbar.
