Discharge (hydrology)
From Wikipedia, the free encyclopedia
In hydrology, the discharge of a river is the volume of water transported by it in a certain amount of time. The unit used is usually m³/s (cubic meters per second). For example, the average discharge of the Rhine river is 2200 m³/s.
The discharge of a river can be estimated by taking the area of a cross-section of the river and multiplying it by the river's average velocity.
In absolute terms, the greater the discharge of a river, the more sediment it may carry. In relative terms the ability to carry sediments depends on the settling velocity, the speed of the flow.

The rate in which the River Discharge is measured in is ussually refered to as Cumecs (Cubic Metres per Second)
