Samenvatting
This manual provides structural design methods for culverts and for improved inlets. Manual methods for structural analysis are included with a complete design procedure and example problems for both circular and box culverts. These manual methods are supplemented by computer programs which are contained in the Appendices. Example standard plans have been prepared for headwalls, wingwalls, side tapered, and slope tapered culverts for both single and two cell inlets. Tables of example designs are provided for each standard plan to illustrate a range of design parameters. (Author/publisher)
