<br />possible with an X3 card because encroachment stations specified on an <br />X3 card are used on every profile of a multiple profile run. <br />The summary printout in Appendix III shows the computed results <br />for the second trial. The second profile produced a profile within <br />the one foot limit. Had the stations of encroachment at Section 0.34 <br />not been adjusted as indicated previously, the computed water surface <br />elevation at Section 0.55 would have exceeded the one foot limit. The <br />third profile, with encroachment stations based on a consideration of <br />alignment of the encroachments and fill requirements, was more conservative. <br />The computed profile was well within the one foot limit. Because the <br />geometry of the sections was considered in the third profile, it <br />would probably 'be the preferred profile. The second profile would <br />reflect the maximum limit for encroachments. The position of the <br />designated floodway and the hydraulic characteristics (e.g., depths and <br />velocities) of the corresponding profile should be carefully reviewed. <br /> <br />15 <br />
