Samples of input and <br /> <br />output data, together with necessary information on the format of <br /> <br />input data, are shown in Appendix D. <br /> <br />The program output can be checked by two methods. First, the <br /> <br />computed profile can be compared to an observed profile at the same <br /> <br />discharge. Second, if data on an actual profile is not available, <br />water surface elevations ~an be computed at several locations by <br />estimation of roughnesses and application of equations of uniform <br />flow. <br /> <br />. <br /> <br />. <br /> <br />A sample output profile is compared to a measured profile in <br /> <br />Appendix E. The sample was extracted from the stream on which the <br /> <br />program was checked. Results of the application are discussed in the <br />following chapter. <br /> <br />< <br />
