Baseflow
The normal level of water. Provided by groundwater.
1 of 12
Quickflow / stormflow
The water which gets into the river as a result of surface run off.
2 of 12
Velocity
The speed flow
3 of 12
Discharge
Volume of water
4 of 12
Hydraulic radius
The measure of of channel effeicency, how effectively water is transported.
5 of 12
Cavitation
Bubbles generated by turbulant flow burst against beds and banks. The explosion creates shock waves which push small particles from the edges of the channel. Common in plunge pools.
6 of 12
Evorsion
The force generated by the weight of water striking the bed and banks.
7 of 12
Competence
The maximum sized particle that can be moved by a stream. It usually increases with velocity.
8 of 12
Capacity
The maximum amount of material a river can move past a certain point in a certain time.
9 of 12
Bed load
The heaviest materual carried by the river it cannot be lifted by the flow and is instead dragged or rolled along ni contact with the bottom of the channel.
10 of 12
Dissolved load
All organic and inorganic material carried in moving water.
11 of 12
Suspended load
All organic and inorganic material carried in moving water.
