**Formula:**`Q = A x V`

## Introduction to Stream Discharge

Stream discharge is calculated by multiplying the cross-sectional area of the stream by the velocity of the water flow. In this formula, ** Q** represents the stream discharge,

**is the cross-sectional area of the stream, and**

*A***is the velocity of the water flow. The result is expressed in cubic meters per second (m**

*V*^{3}/s) or cubic feet per second (ft

^{3}/s) depending on the units used for area and velocity.

## Parameter usage:

`area`

= cross-sectional area of the stream (m^{2}or ft^{2})`velocity`

= velocity of the water flow (m/s or ft/s)

## Output:

`discharge`

= stream discharge (m^{3}/s or ft^{3}/s)

## Data validation

The numbers should be greater than zero.

## Summary

This calculator takes into account the cross-sectional area and velocity of a stream and outputs its discharge. It is not specific to a particular unit of measurement.
