| Abstract | HY-4 provides documentation for a mainframe computer program that calculates the backwater created by a bridge constriction on the basis of a single-cross section. The computer program is based on the design procedures and equations published in HDS No. 1, Hydraulics of Bridge Waterways. This program was developed for the IBM 360 Computer using the problem oriented FORTRAN IV (G) level language. A complete program listing is included as Appendix A. The program consists of two parts. Part I analyzes the natural stream section and produces, at the user's option, the cross section and rating curve plots. After the proposed bridge opening geometry has been superimposed on the flood plain, Part II of the program performs a hydraulic analysis of the constricted bridge waterway opening and determines the velocities and backwater for selected discharges and bridge lengths. The program considers the type of wingwall abutments, piers, eccentricity and skew in the backwater calculations. |
