Question

Quizplus · Accepted Answer

The amount of friction per cubic area in streamflow is actually minimized in wide, deep, smooth-bottomed rivers. This is because there is less interaction between the water flowing near the surface and the riverbed, reducing the amount of friction. In contrast, narrow, shallow, and rough streams have more friction between the water and the riverbed, resulting in a slower flow rate.
