there is less friction caused by the bottom of the river bed and banks by sediment and rocks etc. velocities are said to be fastest at the surface of the river because of this less amount of friction acting upon it. it is also fastest at the centre of the river where it is the deepest.
What else can I help you with?
What does bankfull width depend on?
It depends how far along the river course it is. In theory as you move further down the river's course the bankfull width should increase.
What is a Bankfull Width?
Bankfull width refers to the width of a river or stream when it is at maximum capacity, just before it begins to overflow its banks. It is a key measurement used in river management and flood forecasting to help determine potential flood levels.
What is bankfull dscharge?
Bankfull discharge refers to the flow rate of a river or stream at which the water fills the channel to the point of overflowing its banks. This condition indicates the maximum capacity of the channel before floodwater begins to spill into the surrounding floodplain. It is a critical concept in hydrology and river management, as it helps in understanding flood patterns and designing flood control measures. Bankfull discharge typically occurs during frequent flood events, often estimated to happen on average every 1.5 to 2 years.
Why use bankfull width in hydrology?
The dominant channel forming discharge is often assumed to be the bankfull flow. For example Knighton (1998) argued that "since it seems reasonable to suppose that river channels are adjusted on average to a flow which just fills the available cross-section, dominant discharge has been equated with bankfull flow, thereby giving it additional morphogenetic significance." The dominant discharge is supposed to give the same effects as the whole range of discharges occurring (Brandt, 2000). --- Brandt, S.A., 2000: Classification of geomorphological effects downstream of dams.
