A Level Geography: Water Budgets and River Regimes

What does a water budget show?

• The annual balance between inputs and outputs in a water system

• The total amount of rainfall in a year

• The average temperature of a region

• The population growth rate of a region

Which of the following is NOT a component of the water budget equation P = Q + E ± S?

• Temperature

• Evapotranspiration

• Discharge

• Precipitation

What is the impact of impermeable geology on river regimes?

• Increases surface run-off

• Decreases surface run-off

• Increases groundwater storage

• Decreases precipitation

Which climate type is the UK an example of?

• Arid

• Tropical

• Temperate

• Polar

What can intense rainfall lead to in terms of river regimes?

• Increased groundwater storage

• Decreased surface run-off

• Reduced river discharge

• Quick saturation of the ground

What does a positive water balance indicate?

• A deficit of water

• A surplus of water

• Equal inputs and outputs

• No change in water levels

Which of the following factors can influence river regimes?

• Urbanisation

• Political stability

• Population density

• Cultural practices

What is the role of vegetation in river regimes?

• Decreases groundwater recharge

• Intercepts precipitation and stores it

• Reduces evapotranspiration

• Increases surface run-off

What is the significance of a water budget graph?

• It predicts and monitors soil moisture

• It calculates the population growth rate

• It shows the annual variation in temperature

• It measures the economic development

Which of the following is a factor that does NOT influence river regimes?

• Language spoken

• Geology

• Soil type

• Climate
