• Throughflow
• Direct precipitation onto the channel
• Groundwater flow

4. The lag time on a storm hydrograph is?

• Time between maximum flow and water returning to normal level.
• Time from start of storm to maximum discharge.
• Time between maximum precipitation and peak discharge
• Length of time when river is above bankfull discharge.

5. The reason why interception is lower in winter than in summer in the UK is

• Temperatures are lower.
• Evapotranspiration is reduced.
• UK trees are mainly deciduous.
• Harvesting of crops has occurred.

6. Which of the calculations below for stream ordering is correct?
