• Run-off

• Evapo-transpiration

This is the water balance equation. What are P and Q?

In this water balance graph the month of June sees.....

• Not enough water in the soil for growth

• The water in the soil being used by vegetation

• There being too much water in the soil so flooding is likely

• The water recharging the soil

A River Regime is......

• The changes to precipitation and evapotranspiration in a drainage basin over a year

• The changes to discharge in a river over a year

• The changes to discharge in a river over the length of a period of heavy rain

• The changes to soil moisture over a year
