HY-8 Versions 3.1, 4.1, and 6.0 were developed by Philip L. Thompson and were provided to the Federal Highway Administration (FHWA) for distribution. HY-8 Versions 1.1, 2.1, and 3.0 were produced by the Pennsylvania State University in cooperation with FHWA. The HY-8 Versions 3.0 and earlier versions were sponsored by the Rural Technical Assistance Program (RTAP) of the National Highway Institute under Project 18B administered by the Pennsylvania Department of Transportation. Version 6.0 (Energy, HYD and Route) was produced by GKY and Associates under contract with FHWA. Version 7.0 of HY-8 has been developed by Brigham Young University in cooperation with FHWA. The primary purpose of the first Windows compatible version is to provide graphical user interface (GUI) for the same hydraulic calculations performed in version 6.1 of HY-8. In the course of the development all program functions have been translated to C++. Several minor bugs in version 6.1 have been corrected in HY-8 version 7.0.


HY-8 automated the design methods described in HDS No. 5, "Hydraulic Design of Highway Culverts" dated September 1985, FHWA-NHI-12-029 and in HEC No.14, FHWA-NHI-06-086. Version 6.1 is the last version of the MS-DOS program that was distributed. Hydrologic calculations are available in the Watershed Modeling System (WMS) and in the FHWA Hydraulic Toolbox.


The software has been structured to be self-contained and requires no user's manual. This facilitates its use by roadway design squads. However, the knowledgeable hydraulic engineer will also find the software package useful because it contains advanced features. This help file provides necessary instructions and clarifications.
