of cross-section surveys (Fig. 6a), shows that this bar was emergent after the 1993 flood, but was significantly smaller than in 1996. Following the 1994 flood the bar was barely emergent (Fig. 6b). FIGURE 6c shows that at high flow the bar elevation was similar in 1993, 1994 and 1996. FIGURE 6d then reveals the bar built during the receding limb of the 1996 flood, to achieve the present elevation. Thus, the behavior of this bar during the 1993 and 1996 floods was similar. The emergent bar area was greater in 1996 than in 1993, however. Cross-section 8 at Ouray crosses the detailed study bar of Rakowski (1997). No significant channel change occurred at this cross-section during the 1993 and 1994 floods (Fig. 7a and 7b). The plot of the 1993, 1994 and 1996 high discharge surveys (Fig. 7c) shows that the higher peak flow of 1996 raised the bar elevation at cross-section 8 by 1.5 meters. This plot also demonstrates the increase in the depth of scour during higher peak flows. Dunes were present during the high flow survey of 1996 (Fig. 7d). Channel features emerged following the 1996 flood that were not previously present since 1993 (Fig 8a). The plot of 1994 and 1996 high discharge data shows that no bar existed in this location in 1994. It also shows that during the receding limb of the 1996 flood the bar aggraded 2 m. The 1996 flood series plot of cross-section 12 (Fig. 8b) shows that approximately half of the aggradation occurred by June 10. Topographic Maps Inspection of the available topographic maps for the Ouray study reach shows that the 1996 flood resulted in less complexity than the 1994 and 1995 floods but more than in 1993. Prior to 1996, the topographic maps of Ouray included only the detailed study bar. Subsequently, complexity comparisons are limited to the study bar. A comparison of the 1996 and 1993 bar topography (Figs. 14 and 15) shows that following the 1996 flood the bar topography was more complex, primarily because of the formation of spurs along the bar margin. This result suggests that antecedent conditions, flood duration and recession characteristics 12
