Culvert Analysis & Design

CulvertMaster calculates headwater elevations based on both inlet and outlet control conditions. No more messy nomographs. Inlet control calculations use weir and orifice equations. Outlet control calculations use Haestad Methods' incredibly stable gradually varied flow hydraulic algorithms, which do not fail in the toughest modeling situations including hydraulic jumps, mixed gravity, and pressure flow; and adverse or horizontal slopes.


  • Analyze multiple culverts of different shapes and sizes at the same embankment
  • Compute roadway overtopping
  • Use CulvertMaster's automatic design to determine the best size culvert for your system
  • Calculate catchment runoff using the SCS peak discharge method, the Rational method, or enter a predetermined flow
  • Determine the tailwater elevation based on a regularly or irregularly shaped channel
  • Calculate and report headwater for both inlet and outlet control conditions
  • Haestad Methods' gradually varied flow hydraulic algorithms calculate inlet and outlet controlled conditions without the inaccuracies of nomographs
