HY-8 Culvert Analysis Program - Phase Three of Development Efforts

The HY-8 is a computerized implementation of the Federal Highway Administration (FHWA) culvert hydraulic approaches and protocols. The FHWA publication "Hydraulic Design Series 5: Hydraulic Design of Highway Culverts" (HDS-5) [publication FHWA-NHI-01-020, May 2005 revision] documents the technical methods applied in the HY-8 program and should be considered the primary technical reference for the software. In 2005, the FHWA contracted with the Brigham Young University to develop a 32-bit (and 64-bit) Windows compatible version of HY-8. This version provided graphical user interface (GUI) for the same hydraulic calculations performed in DOS versions of HY-8. FHWA intended to plan and fund this development effort using a series of planned phases. The first phase resulted in an initial release (version 7.0) that performed basic culvert hydraulics. The second phase (version 7.1) incorporated energy dissipater module; performed hydraulic analyses of embedded culverts; allowed use of modified outlet loss coefficients; incorporates dynamic culvert shape database with new materials; and implemented various improvements, technical updates, and bug corrections. The objective of this research effort is to continue the phased development of HY-8. The effort would be funded by FHWA and other State departments of transportation (DOTs) contributors (PFP members). The anticipated scope of work consists of continued development efforts on the HY-8 software (beginning with phase three of the on-going development effort).
