<br />Draft Final Completion Report to UDWR for Contract #93-1070. Amendment 3 <br /> <br />22 <br /> <br />METIIODS <br /> <br />Field Measurements <br /> <br />Detailed topographic surveys <br /> <br />In July 1994, the topography of one bank-attached compound bar within the study reach was surveyed using a <br /> <br />laser theodolite. Three separate surveys were translated and rotated onto a common base. Surveyed cross sections were <br /> <br />used to augment the topographic survey. Similar surveys of detailed topography were made of this bar in 1993 by P. <br /> <br />Reed Krider (1994), and all maps were digitized into a GIS to permit quantitative comparisons and analysis. <br /> <br />Cross Section Surveys <br /> <br />The Ouray NWR was the site of cross section surveys in 1986, 1987, 1988, 1990, and 1991 (Smith, 1993, <br /> <br />wriuencomm.). In 1992, we reoccupied 6 of the 10 cross sections established by Andrews and Nelson (1989). <br /> <br />Additionally, in 1992. 4 cross-sections were added within the reach. and in fall 1993, an additional 2 cross-sections were <br /> <br />added on the upstream end of the study reach. These cross sections (Table 2, Fig. 1 0) were used as input to the flow and <br /> <br />sediment transport model of Andrews and Nelson (1989). <br /> <br />Table 2. Dates of cross-section surveys and discharge at the time of the surveys. The May 21, 1993 survey was <br />condt1cted at high flow, and only water surface stage and maximum channel depth were measured at each cross section. <br />Asterisks indicate that field maps of flow patterns were made within the 15-lan reach. <br />
