River discharge is the volume of water flowing through a river channel. This is the total volume of water flowing through a channel at any given point and is measured in cubic metres per second (cumecs).
Discharge is calculated as follows:
cross sectional area of a river or stream x mean velocity of water
- Describe three relationships shown on the diagram above e.g. as discharge increases, velocity increases
- Make simple sketches of the diagram above
- Read 107 - 109 (Core Book): Discharge, stream flow and channel shape.
- Make detailed notes under the different headings.
