  • A windows PC, with administrative rights to install HY-8
  • A letter size printer for the class exercises


This course will guide you through using HY-8 to analyze culverts. You'll watch short demonstration videos and then apply what you've learned to class exercises, and then check you work. Focus is on applying the software to real problems - does not delve deeply into hydraulics, hydrology, erosion control, fish passage, or construction.
