What is CulvertMaster?
CulvertMaster is an extremely powerful yet easy-to-use calculator product that helps you design new culverts and analyze existing culvert hydraulics. Analyze everything from single-barrel crossings to complex embankment cross-drain systems, with different shapes and sizes, special tailwater considerations, and roadway overtopping considering watershed data, culvert characteristics, and even weir geometry. When you design and analyze culverts, easily select from a library of standard culvert shapes, materials, and entrance conditions, then compute culvert headwater and tailwater elevations using calculation methodologies outlined in Hydraulic Design Series Number 5 from the U.S. Federal Highway Administration.
Data entry and manipulation are flexible and straight forward with CulvertMaster. You simply enter data in clearly labeled fields with full context-sensitive help and click to calculate. Quickly navigate using tabbed dialog “worksheets” to edit watershed data, tailwater conditions, and profile information. You can conveniently organize all your designs and analyses for the same project within a single file. When you interpret and present your modeling results, you can easily view detailed tables, reports, rating curves, and more.
CulvertMaster offers three flexible simulation types that you can use for all phases of your projects:
- Quick culvert calculator
For simple culverts with known characteristics, this simulation type allows you to plug in the data and solve for what you need. Its worksheet style dialog requires the minimum amount of descriptive input information to solve for discharge, headwater elevation, or culvert size.
- Culvert analyzer
For more complex systems with multiple barrels, different shapes and sizes, special tailwater considerations, and roadway overtopping, you can use this simulation type to
- verify the hydraulic performance of existing culverts; analyze complex situations such as main-stream culverts working in combination with relief culverts in overbank areas
- perform road overtopping analysis of existing culverts or new designs, or
- supplement existing culvert structures to correct inadequate capacities resulting from urbanizing watersheds or undersized crossdrain conditions
- Culvert designer
You can compare several proposed options, incorporate these design trials into complex hydraulic analyses, and evaluate the results. In this design mode, you would create individual culvert trials and solve for
- size of a culvert of a specified shape, material, and roughness to pass the design discharge under design elevation headwater conditions
- discharge for a specific culvert under design elevation headwater, or
- headwater elevation for a specific culvert under design discharge conditions
Hydraulics and hydrology
CulvertMaster computations use the widely accepted US Federal Highway Administration’s Hydraulic Design of Highway Culverts (HDS-5) methodologies, allowing you to solve for whatever hydraulic variables you don’t know, such as culvert size, peak discharge, and headwater elevation.
Flow calculations handle pressure and varied flow situations such as backwater and drawdown curves. Design discharge can be calculated using either the Rational or SCS peak discharge method. Rainfall information is calculated using rainfall tables, equations, or the National Weather Services’ Hydro-35 data. CulvertMaster also plots Intensity-Duration-Frequency (IDF) curves from rainfall data. You can reuse this data for all projects in that region.
