Culvert Design, step by step

Two control cases. The one needing more headwater governs.

  1. Estimate the design flowCatchment area, return period and the method your standard names.
  2. Pick a trial sizeShape, material and cover depth that suit the embankment above.
  3. Test inlet controlHeadwater set by the inlet geometry, with flow shooting through.
  4. Test outlet controlHeadwater set by barrel friction and the tailwater level.
  5. Take the higher headwaterWhichever case demands more upstream depth is the governing one.
  6. Check scour and passageOutlet protection, plus a bed for fish or mammals if required.

Who is the Culvert Design poster for?
Culvert Design belongs to the Civil Engineering section rather than to a school year, because engineering is not something one grade owns. Anyone learning water resources can pin it up — a beginner, a student mid-course, or someone revising years later.
When should you use the Culvert Design poster?
Putting a watercourse under a road, track or embankment. A wall chart earns its place by being glanceable from where the work is happening, so Culvert Design belongs on the wall where that engineering work actually happens, within glancing distance, rather than filed away.
What other posters go with Culvert Design?
Continuity & Energy, Groundwater & Wells and The Water Balance sit alongside Culvert Design in the Civil Engineering section. Printed together they make a wall rather than a single sheet, which is how a reference set actually gets used.Continuity & EnergyGroundwater & WellsThe Water Balance
Is the Culvert Design poster free to download and print?
Yes. Culvert Design downloads as a free PDF with no account, no email and no watermark, like everything else in the Civil Engineering section. Print as many copies as you like for a home, a classroom, a library or a tutoring group; reselling the file is the only thing the licence rules out.Read the licence
What size does the Culvert Design poster print at?
Culvert Design is a vector PDF laid out for US Letter, and prints on A4 with Fit to page — the same file, no separate download. Because every mark on it is drawn rather than photographed, it stays sharp enlarged to A3, A2 or A1 at a copy shop. Colour carries emphasis only, so a greyscale print of Culvert Design loses nothing.Printing guide
