<br />(Figure I). The staging table provides estimates <br />of modeled instream hydraulic parameters at <br />stages above and below the measured discharge. <br />Page five summarizes measured and calculated <br />flows, waterlines, and depths (Figure 1). It also <br />presents estimates of mean velocity, Manning's <br />"n", water slope, and upper and lower <br />streamflow limits within which the instream <br />flow recommendation should fall. In general, <br />hydraulic models based upon Manning's <br /> <br />Figure D. <br /> <br />The R2CROSS Menu <br /> <br />'~''''.''T.' <br />~ <S;~ <br />~ <br /> <br />I <br />I <br />I <br />i <br /> <br />!
