Enter the vertical stream difference in elevation and the horizontal stream difference into the Stream Gradient Calculator. The calculator will evaluate the Stream Gradient.

## Stream Gradient Formula

The following two example problems outline the steps and information needed to calculate the Stream Gradient.

SG = VS / HS

Variables:

- SG is the Stream Gradient ( )
- BS is the vertical stream difference in elevation
- HS is the horizontal stream difference

To calculate the stream gradient, simply divide the vertical stream difference by the horizontal stream difference.

## How to Calculate Stream Gradient?

The following steps outline how to calculate the Stream Gradient.

- First, determine the vertical stream difference in elevation.
- Next, determine the horizontal stream difference.
- Next, gather the formula from above = SG = VS / HS.
- Finally, calculate the Stream Gradient.
- After inserting the variables and calculating the result, check your answer with the calculator above.

**Example Problem : **

Use the following variables as an example problem to test your knowledge.

vertical stream difference in elevation = 300

horizontal stream difference = 200

SG = VS / HS** **= ?
