the angle of repose and the specific gravity for the rock were assumed to be 4l degrees and 2.7, <br />• respectively. <br />• <br />3.5.4 Results of Analyses <br />The flows contributed by each basin into the diversion channel aze summarized in Table 3-2. A <br />table of the detailed basin chazacteristics and the calculated lag times is included in Appendix <br />B.1 of this repoR. In addition, a table of stream routing data used in the HEC-1 model is a]so <br />included in Appendix B.l. The HEC-1 input and output aze located in Appendix B.2 of this <br />report. The results of the HEC-l model were used for the diversion channel design. <br />Table 3-2 Basin Flow Contributions <br />Basin ID Flow <br />(cfs) <br />Basin 1 40 <br />Basin 2 10 <br />Basin 3 l 1 <br />Basin 4 8 <br />Basin 5 36 <br />Basin 6 38 <br />Basin 7 16 <br />Basin 8 1 l <br />Basin 9 4 <br />Basin 10 3 <br />Basin l l I <br />Basin 12 1 <br />Basin 13 15 <br />Basin 14 5 <br />Basin I S 3 <br />Basin l6 5 <br />Basin 17 14 <br />Basin 18 20 <br />Table 3-3 summazizes the results of channel flows and rock sizing for each channel segment to <br />be lined with riprap.
