The host agency is responsible for providing computers with the following minimum configuration: 1.6 GHz Intel Pentium III Processor or equivalent with 512 MB RAM, 100 MB available disk space, CD-ROM drive, and Windows XP. One computer is required for every two participants.

The course provides engineers and designers with hands-on computer experience in the selection and application of software tools commonly applied for highway hydraulics including estimating peak flows and hydrographs, as well as the analysis and design of storm drains, culverts, detention basins, and channels. The Watershed Modeling System (WMS) will be the Windows interface used for most applications. Software covered in the course includes:

1. NFF (National Flood Frequency Program)

2. SCS TR-55


4. FHWA Storm Drain for design of pipes and inlets

5. HY8 (Windows version) for culvert and energy dissipator analysis and design

6. WMS detention basin and channel calculators for detention basin and channel design


Upon completion of the course, participants will be able to:

  • Define a drainage outlet and delineate a watershed using WMS
  • Compute peak flows using NFF and TR-55
  • Perform normal depth and stability calculations using the WMS channel calculator
  • Design a culvert using HY8
  • Select and size an energy dissipator using the HY8 energy dissipator software
  • Design and analyze storm drain inlets and pipes using WMS and the FHWA storm drain program
  • Route a hydrograph through a detention basin using the WMS detention basin calculator


Highway engineers and designers responsible for the hydrologic and hydraulic aspects of designing storm drains, culverts, detention basins, and channels. Attendees should have a basic knowledge of hydrology and hydraulics. The course will briefly review theory, but will focus on hands-on problem solving.
