Stream Gradient Calculator

Formula

The formula to calculate the Stream Gradient (SG) is:

\[ \text{SG} = \frac{\text{VS}}{\text{HS}} \]

Where:

SG is the Stream Gradient
VS is the vertical stream difference in elevation
HS is the horizontal stream difference

What is Stream Gradient?

The stream gradient is the rate of elevation change over a horizontal distance. It is calculated by dividing the vertical stream difference by the horizontal stream difference. This metric is used to understand the steepness and flow characteristics of a stream.

Example Calculation

Let's assume the following:

Vertical Stream Difference in Elevation (VS): 100 units
Horizontal Stream Difference (HS): 2000 units

Step 1: Calculate the Stream Gradient (SG):

\[ \text{SG} = \frac{100}{2000} = 0.05 \]

Therefore, the Stream Gradient is 0.05.
