Paper 2
The speed of the river’s flowing water, usually measured in metres per second ().
Revise: River Characteristics and ProfilesDischarge and average velocity have increased, and sediment is generally smaller and more rounded.
Describe velocity as generally increasing downstream, not increasing at every point: rapids and other local conditions create exceptions.
A gentler gradient does not necessarily mean a lower velocity: average velocity generally increases downstream.
