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

 
 
  1. Describe three relationships shown on the diagram above e.g. as discharge increases, velocity increases
 

ACTIVITIES

  1. Make simple sketches of the diagram above
  2. Read 107 - 109 (Core Book): Discharge, stream flow and channel shape.
  3. Make detailed notes under the different headings.
