16.4.1. Water Budget Method

Try these first

1. 1.

   What does E represent in the Water Budget Method?

   Hint

   Think about what happens to the water from a lake.

2. 2.

   What contributes to the inflow (I) in the equation?

   Hint

   Consider sources like rivers or rainfall.

3. 3.

   What does the equation E = I + P - O - ΔS represent?

   • A calculation for precipitation
   • An estimation of evaporation
   • A measurement of water temperature

   Hint

   Think about what we are measuring in relation to water.

4. 4.

   True or False: The Water Budget Method only applies to large reservoirs.

   • True
   • False

   Hint

   Remember, water budget concepts may also apply to lakes or ponds.

5. 5.

   During a study, a lake had an inflow of 8,000 m³, a precipitation of 1,500 m³, an outflow of 4,000 m³, and ΔS was found to be +2,000 m³. Calculate the evaporation rate and explain the significance in water resource management.

   Hint

   Break down each component methodically.

6. 6.

   Evaluate the challenges of estimating evaporation in a fast-flowing river compared to a static reservoir using the Water Budget Method.

   Hint

   Consider how different environments affect measurement methods.
