The FHWA Office of Bridge Technology is pleased to announce the release of version 7.0 of the FHWA's Culvert Hydraulic Analysis Program, HY-8. The HY-8 program operates within a graphical user interface compatible with the Windows operating system. The HY-8 program is a computerized implementation of FHWA culvert hydraulic approaches and protocols. The HY-8 program is a free, public domain software.
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.
Attached to this memorandum is a copy of the "HY-8 Quick Start" document that provides information about downloading and installation of the program, some important differences between the older DOS version and this new Windows version, a simple tutorial problem to introduce users to the basic operation of HY-8, and means to report bugs or other problems to FHWA via e-mail at CommentsOnHY8Version7.email@example.com. The HY-8 Quick Start document contains the links to download the HY-8 installation package. We strongly recommend that users read the installation instructions contained in this document before downloading the HY-8 program.
As described in the HY-8 Quick Start document, the HY-8 installation file includes the HDS-5 document as a portable document format (PDF) file. The HDS-5 document is also accessible from the HY-8 program help menu. A hard copy of HDS-5 can be created by printing the PDF file.
The HY-8 program has extensive on-line help that assists users in the understanding operations and features of the software. This is in the form of a hyper-linked help file available from the help menu or by selecting help buttons or icons from the graphical user interface. While the help file is organized to provide context-sensitive help, it can be printed out and organized into a hard copy manual.
A copy of this memorandum and attachment is being e-mailed directly to the hydraulics unit in each State department of transportation.
If you have any questions, please contact Mr. Joe Krolak, Senior Hydraulics Engineer, at (202) 366-4611.
