I Lower Smelter Boatina Park I <br />= do not touch <br />= <br />values that an be ad'uste <br />This spreadsheet can be used to help develop average depths of high and low flow channels. Actual dimensions <br />can be set during final design using these numbers as a guideline. Please only adjust cells that are blue. Other <br />cells should not be adjusted at all. Plot values at the bottom can be inserted into HEC -RAS directly using cut and <br />paste. All computations are made using the wier equation and are separated using Shipley's vertical separation <br />method. Dimensions are based on width PROJECTIONS (i.e. the plot shows shadow on the wall of light shown <br />through channels). Arc length is not shown. Analysis is vertical so location of low flow within high flow is not <br />important and will vary according to project constraints. This is not a comprehensive listing of limitations of <br />analysis and spreadsheet should be used by experienced designer for guidance purposes only. <br />Figure 13. Approximate weir calculations for Structure 15 at the lower end of the proposed <br />boating park. <br />Figure 13 shows that at a low flow width of 36 feet the depth in the low flow will be 1.5 feet <br />at 200 cfs. The high flow width of 100 feet creates a center flow depth of 4.2 feet at a flow <br />of 1800 cfs. These dimensions are appropriate for the character of the Animas River at this <br />location. Of note is that this higher flow, of 1800 cfs, is not claimed in the requested flow <br />regime. The claimed peak flow of 900 cfs provides for this Structure's intended purpose as a <br />novice /intermediate instructional and training feature. <br />31 <br />- <br />© <br />- <br />t1�II2�Zi•] <br />-� <br />Figure 13.
