18.1. Nature and Magnitude of Reservoir Evaporation

Try these first

1. 1.

   What is reservoir evaporation?

   Hint

   Think about water changing state!

2. 2.

   Name one climatic factor that influences evaporation.

   Hint

   Consider weather elements!

3. 3.

   What does reservoir evaporation primarily refer to?

   • Loss of water to evaporation
   • Increase in water storage
   • Reduction of water quality

   Hint

   Focus on what happens to the water!

4. 4.

   True or False: Evaporation rates do not vary with climatic conditions.

   • True
   • False

   Hint

   Think about weather effects!

5. 5.

   Given that a reservoir has a surface area of 150 acres and average evaporation rates of 2.0 m/year, calculate the volume of water lost annually in cubic meters.

   Hint

   Convert acres to square meters first before calculating.

6. 6.

   Discuss how the choice of evaporation estimation methods might change based on region—arid vs temperate climates.

   Hint

   Consider the differences in water availability and climatic conditions.
