Stream Velocity Calculator

Stream Velocity Formula

The stream velocity is calculated using the following equation:

\[ SV = \frac{Q}{W \times D} \]

Where:

• SV is the stream velocity (ft/s)
• Q is the volumetric flow rate (ft³/s)
• W is the width of the stream (ft)
• D is the depth of the stream (ft)

What is a Stream Velocity?

Definition: Stream velocity is the linear speed at which water flows through a stream or river, measured in feet per second (ft/s). It is an essential parameter in hydrology for understanding water movement, erosion potential, and sediment transport.

How to Calculate Stream Velocity?

To calculate the stream velocity:

1. Measure the flow rate of the stream in cubic feet per second (ft³/s).
2. Measure the width of the stream at the cross-section of interest.
3. Measure the depth of the stream at the same cross-section.
4. Apply the formula: Divide the flow rate by the product of the stream width and depth to find the stream velocity.

This calculator helps you quickly and accurately determine the stream velocity, which is vital for various water management and environmental studies.
