Predicted evolution of bar topography at 5 cross sections during a discharge of 50 <br />m3/s for 2 days. Dashed line shows original topograpby and sOlid. line shows final <br />topography. <br /> <br />flows less than 275 m3/s. In contrast, however, sediment was deposited on the crest <br />of the bar at any discharge large enough to cover the entire bar to a depth of several <br />centimeters. Although the rate of sediment deposition on the bar crest is <br />substantially less than the maximum computed rate of scour and fill in the Ouray <br />reach, given sufficient time, about one week at a discharge of 475 m3/s, the crest of <br />
