Culvert Design Calculator

This calculator is designed for civil engineers to compute culvert design specifications efficiently, utilizing authoritative engineering data and standards.

Interactive Calculator

Results

Hydraulic Radius 0.00
Velocity (m/s) 0.00

Data Source and Methodology

All calculations are based on the Hydraulic Design Series provided by the Federal Highway Administration (FHWA). For further details, refer to LMNO Engineering. All calculations strictly follow the formulas and data provided by this source.

The Formula Explained

Q = A × V, where Q is the flow rate, A is the cross-sectional area, and V is the velocity.

Glossary of Terms

Practical Example

For a culvert with a diameter of 2 meters and a flow rate of 1.5 m³/s, the hydraulic radius is 0.5 meters and the velocity is 0.75 m/s.

Frequently Asked Questions (FAQ)

What is a culvert?

A culvert is a structure that allows water to flow under a road, trail, or similar obstruction.

How is the hydraulic radius calculated?

The hydraulic radius is calculated by dividing the cross-sectional area of flow by the wetted perimeter.

Why is velocity important in culvert design?

Velocity is crucial as it affects the potential for erosion and sediment transport.

What materials are used for culverts?

Culverts are commonly made from concrete, steel, or plastic.

How do I ensure compliance with local regulations?

Consult local engineering standards and guidelines to ensure compliance.
