Energy of River
The speed and volume of a river are influenced by several interrelated factors. The wetted perimeter of the river, which refers to the area where the river water is in contact with its bed and banks, plays a significant role in determining speed; a larger wetted perimeter leads to more friction and thus slower flow, while a smaller wetted perimeter results in faster flow due to reduced friction.
