Question

Quizplus · Accepted Answer

Stream gradient is defined as the drop in elevation of a stream divided by the distance the water travels. This gradient determines the velocity of water and the erosive power of the stream. A steeper gradient indicates a faster flow and more erosive power, while a gentle gradient indicates a slower flow and less erosive power.
