18.1.3. Quantification of Reservoir Evaporation

Try these first

1. 1.

   What is the primary purpose of quantifying reservoir evaporation?

   Hint

   Think about how water management impacts irrigation and drinking water.

2. 2.

   Name the formula used in the pan evaporation method.

   Hint

   What does E stand for in the formula?

3. 3.

   What is the primary aim of quantifying reservoir evaporation?

   • To increase water loss
   • To manage water resources effectively
   • To decrease reservoir sizes

   Hint

   How does appropriate water usage improve resource availability?

4. 4.

   True or False: The Penman method is a simple method that doesn’t consider climatic factors.

   • True
   • False

   Hint

   Think about what makes a method complex.

5. 5.

   If a reservoir has a measured pan evaporation of 1.2 m/year and a pan coefficient of 0.7, what is the estimated evaporation from the reservoir?

   Hint

   Use the Pan evaporation formula we've discussed.

6. 6.

   Explain how seasonal changes affect the annual evaporation rates from a reservoir. What methods can be adapted to account for this variability?

   Hint

   Consider why water usage may vary across seasons.
