The Office of Bridge Technology is pleased to announce the release of version 7.1 of the HY-8 Culvert Hydraulic Analysis Program (HY-8 7.1). The HY-8 7.1 represents the second phase of the FHWA’s multi-phase upgrade of its culvert hydraulics software approaches and protocols. Notable new features completed during this phase include:
The HY-8 7.1 has on-line Help that assists users in understanding software operations and features. The technical methods applied in HY-8 are based on the FHWA publications: “Hydraulic Design Series 5: Hydraulic Design of Highway Culverts” (HDS-5), May 2005 and “Hydraulic Engineering Circular 14: Hydraulic Design of Energy Dissipaters for Culverts and Channels” (HEC-14), Third Edition, July 2006.
Attached to this memorandum is a copy of a “HY-8 Quick Start” document that provides information on background; program downloading and installation; some important differences between older versions and HY-8 7.1; and ways to report bugs or other problems.
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 of my staff at (202) 366-4611.
