How to calculate the gradient of a stream?
Understand the Problem
The question is asking how to determine the gradient of a stream, likely referring to the slope or incline of a streambed. This involves understanding the change in elevation over a certain distance along the stream.
Answer
gradient = vertical change in altitude / horizontal distance
The gradient of a stream is calculated by dividing the vertical change in channel (altitude) by the horizontal distance between two points along the stream.
Answer for screen readers
The gradient of a stream is calculated by dividing the vertical change in channel (altitude) by the horizontal distance between two points along the stream.
More Information
Gradient is an important factor in the study of hydrology and geomorphology as it influences stream velocity and erosion patterns.
Tips
Common mistakes involve incorrectly measuring the distances or confusing vertical with horizontal measurements.
