HY-8

FHWA ❘ Freeware

HY-8 is a software program developed by the US Federal Highway Administration (FHWA) to aid in the design and analysis of highway culverts. It is available for free download on their website and is widely used by transportation engineers and designers.

The program uses hydraulic models to simulate water flow through a culvert and analyze its performance. This information is used to determine the appropriate size and shape of the culvert to ensure efficient water flow and prevent damage to the surrounding environment.

HY-8 is user-friendly and allows for the input of various parameters, such as culvert geometry, hydraulic data, and soil properties. It also provides detailed reports and allows for the visualization of results through graphs and tables.

HY-8 is a valuable tool for transportation engineers and designers who need to design safe and efficient culverts for highway drainage systems.
