<br />tions is illustrated. the concept of calculating profiles for several <br />discharges simultaneously is described. and techniques are presented <br />which in most cases will reduce the number of times critical depth <br />must be calculated. <br />Several computer programs are available for calculating water <br />surface profiles. These are reviewed in reference 3. The program <br />"Water Surface Profiles" presented in Appendix 2 of Volume 1 of this <br />report has received widespread acceptance throughout the United States. <br />It has been in use and under development since 1964 and provides the <br />capability to analyze the full range of water surface profile problems <br />normally experienced in the Corps of Engineers. <br />When profiles are calculated manually. major discrepancies are <br />easily spotted. However, when computers are used, this is often not <br />the case. It is very important. therefore. that profiles determined <br />by electronic computers be closely reviewed when the job is completed. <br />For example. large changes in water surface elevation, slope or velocity <br />should be logically substantiated regardless of the method of computa- <br />tion. <br /> <br />1.04 <br />
