Hydraulic Design Series Number 5 (HDS 5) originally merged culvert
design information contained in Hydraulic Engineering Circulars (HEC) 5,
10, and 13 with other related hydrologic, storage routing and special
culvert design information. This third edition is the first major
rewrite of HDS 5 since 1985, updating all previous information and
adding new information on software solutions, aquatic organism passage,
culvert assessment, and culvert repair and rehabilitation. The result is
a comprehensive culvert design publication. The appendices of the
publication contain the equations and methodology used in developing the
design charts (nomographs) and software programs, information on
hydraulic resistance of culverts, the commonly used design charts, and
Design Guidelines (DG) illustrating various culvert design calculation
procedures. The number of design charts provided has been reduced
recognizing the increased use of software solutions...
