The Stream Gradient Calculator is a powerful tool used to determine the gradient of a stream, providing valuable insights into the topography and characteristics of the terrain. By inputting the change in elevation between two points along the stream and the horizontal distance between those points, the calculator employs a straightforward formula to calculate the stream gradient (G):
Stream Gradient (G) = (Change in Elevation (ΔE)) / Horizontal Distance (ΔD)
Breaking down the formula:
- Stream Gradient (G): Represents the slope or steepness of the stream.
- Change in Elevation (ΔE): Indicates the difference in elevation between the selected points along the stream.
- Horizontal Distance (ΔD): Refers to the horizontal span between the two chosen points.
General Terms Table
For ease of use, here’s a table of general terms often searched by users, providing a quick reference without the need for manual calculations:
| Term | Definition |
|---|---|
| Stream Gradient (G) | The slope or steepness of the stream. |
| Change in Elevation | The difference in elevation between two points. |
| Horizontal Distance | The horizontal span between two selected points. |
Example of Stream Gradient Calculator
Let’s consider a practical example to illustrate the application of the Stream Gradient Calculator:
- Change in Elevation (ΔE): 50 meters
- Horizontal Distance (ΔD): 100 meters
Using the formula, we can calculate the Stream Gradient (G):
Stream Gradient (G) = 50 / 100 = 0.5
Therefore, the stream gradient in this scenario is 0.5 meters per horizontal meter.
Most Common FAQs
A: Stream gradient is crucial for understanding the terrain, aiding in land management, and predicting water flow behavior.
A: Yes, the calculator is applicable to any flowing water body, including rivers.
A: While there are no strict categories, lower values suggest gentler slopes, while higher values indicate steeper terrain.
