River dicharge is the volume of water that flows in a river per second.

Measured in cumecs - m3/s

River discharge is affected by:

• Climate - The higher the temperature , the lower the discharge as evaporation is higher.
• Removal of water (abstraction) - reduces discharge.

Hydrographs:

Hydrographs are graphs of a river's discharge over…
