1.2. The Water-Budget Equation

Try these first

1. 1.

   What does 'P' represent in the Water-Budget Equation?

   Hint

   Think about what happens when it rains.

2. 2.

   In the Water-Budget Equation, what does 'ET' stand for?

   Hint

   Consider how water is lost from plants into the atmosphere.

3. 3.

   What does 'Q' stand for in the Water-Budget Equation?

   • Precipitation
   • Runoff
   • Infiltration

   Hint

   It's what happens to water after a rainstorm.

4. 4.

   True or False: Evapotranspiration includes only evaporation.

   • True
   • False

   Hint

   Consider what plants do with water.

5. 5.

   A scientist finds that over one year, a catchment area experienced 200 mm of precipitation, 80 mm of runoff, 50 mm of evapotranspiration, and 10 mm of infiltration. Determine the change in water storage (ΔS).

   Hint

   Use the Water-Budget Equation and plug in the provided numbers.

6. 6.

   Consider a scenario where increased urbanization causes runoff (Q) to rise significantly. Discuss how this might affect local ecosystems and water management practices.

   Hint

   Think about the environmental consequences of changing runoff patterns.
