Explain How does the gradient of a river affect<br> its flow?
djverab [1.8K]

Explanation:

The flow of the river is dependent upon the position along the stream in terms of the gradient. Near the top of a high gradient, the flow will be less than that near the bottom. Likewise, the steeper the river's gradient, the faster the flow of water (due to the pull of water down the gradient by gravity).
