Hydraulic Design of Highway Culverts

The purpose of this publication is to provide information for the planning and hydraulic design
of culverts (Figures 1.1 and 1.2). Chapter 2 provides a summary of design considerations
including hydrology, site data and site assessments. Chapter 3 provides detailed information
on the hydraulic design of the barrel (size, shape, material) and the inlet configuration (pipe
end section, headwalls, wingwalls, bevels, and tapers). Chapter 4 provides an overview of
aquatic organism passage (AOP) design concepts. A wide range of assorted design topics
including bends, junctions, erosion, sedimentation, site modifications, structural
considerations, broken back culverts, storage routing, and failure modes is summarized in
Chapter 5. Finally, Chapter 6 discusses culvert repair and rehabilitation.
