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.

"Version 7.5... contains two new calculators: a) a calculator to assist with the FHWA's culvert aquatic organism passage (AOP) design procedure, which is described in detail within Hydraulic Engineering Circular 26, "Culvert Design for Aquatic Organism Passage, First Edition" (HEC-26), and b) a calculator to determine the variation in cross-sectional flow velocity from the culvert wall to the centerline, which is described within Research Publication No. FHWA-HRT-14-064, 'Fish Passage in Large Culverts with Low Flows'. Improvements made to this version of the software include: corrections to the AOP calculator, a correction to the calculation of roadway overtopping for various scenarios, a correction to the calculation of composite Manning's n values for user defined shapes, edits to the Saint Anthony Falls (SAF) Energy Dissipator routine, and edits to the Riprap Basin Dissipator routine."
