Factors Affecting a River's Velocity | Sciencing

A river’s velocity refers to the speed at which water moves through its channel. The velocity of a river is determined by many factors, including the shape of its channel, the gradient of the slope that the river moves along, the volume of water that the river carries and the amount of friction caused by rough edges within the riverbed.
