The supporting calculations are shown in the appendix of <br />this report and the results are as follows: <br /> <br /> EVANS GULCH <br /> Drainage Peak Discharges ( cfs) <br /> Location Area (Sq. Mi.) 10 50 100 500 <br />l. Downstream Limit 7.8 108 166 190 255 <br />2. Upstream Limit 4.0 71 106 121 159 <br /> <br />Since the basin size of Evans Gulch is small, a comparison with <br />other studies in the area is difficult. Figure 14 shows the <br />~)comparison of the results of this analysis with other studies in <br />the area. The comparison shows a reasonable agreement. <br /> <br /> <br />~r~ ~~(~~ ~~ <br />PavkvtflL- C/vUt-ev .A;~? )I/lrfvw ~j/rv <br />&ul-ftN ~f ih') ~~ ~:Vt/lnV ~ r€> <br />~ I~(A~ &/ ~~'1 all~,r W4-I- fc4y 1~. <br />A <br /> <br />-6- <br /> <br />---"- <br />
