Abstract <br />Hydraulic Design Series No. 5 combines culvert design information previously con- <br />tained in Hydraulic Engineering Circular (HECI No.5, No. 10, and No. 13 with <br />hydrologic, storage routing, and special culvert design information. The result is <br />a comprehensive culvert design publication. Hydrologic analysis methods are de- <br />scribed, and references cited. Culvert design methods are presented for both con- <br />ventional culverts and culverts with inlet improvements. Storage routing techniques <br />are included which permit the designer to account for ponding effects upstream of <br />the culvert. Unique culvert applications, erosion and sediment control, debris <br />control, structural aspects, and long span culverts are discussed and references <br />cited. Inlet control, outlet control, and critical depth design charts, many of <br />which are newly developed, are included for a variety of culvert sizes, shapes, <br />and materials. New dimensionless culvert design charts are provided for the de- <br />sign of culverts lacking 'conventional design nomographs and charts. The <br />appendices of the publication contain the equations and methodology used to con- <br />struct the design charts, information of the hydraulic resistance of culverts, <br />and methods of optimizing culvert design using performance curves and inlet de- <br />pression. Calculation forms are provided for most of the design methodologies in <br />the manual. <br />17. Key Words 18.
