This manual provides hydraulic design methods for circular and rectangular culverts with improved inlets. Improved inlets are bevels, side-tapers, and slope-tapers which are modifications to the culvert entrance geometry . These improvements can greatly increase the performance of a culvert which is operating in inlet control. Design charts, tables and computation sheets are provided in the manual.
