  • Abstract:
    HY-8 automates culvert hydraulic computations utilizing a number of essential features that make culvert analysis and design easier. An HY-8 User Manual is included with the software installation (access via 'Help' button on top toolbar) to provide important information on the technical features, capabilities, and limitations of the software.

    Improvements made to this version of the software include the following: User-defined culverts are normalized by the invert in front-view plots (calculations did not need to be updated). Water Surface Profile Data for culverts with decreasing station computed correctly. Fixed headwater line length in high headwater plots. Fixed an error related to first roadway station that caused overtopping calculations to fail.
