4. Reservoir Evaporation and Its Reduction

Try these first

1. 1.

   What is reservoir evaporation?

   Hint

   Consider how water turns into vapor.

2. 2.

   Name one method to reduce reservoir evaporation.

   Hint

   Think of barriers or coverings.

3. 3.

   What is a primary method for reducing evaporation in reservoirs?

   • Increase sunlight
   • Use surface covers
   • Add more water

   Hint

   Think of what you can place on the water.

4. 4.

   True or False: Windbreaks increase evaporation from water surfaces.

   • True
   • False

   Hint

   Consider what wind does to water.

5. 5.

   Determine the effectiveness of combining surface covers and windbreaks on a specific reservoir. Provide calculations for expected reduction in evaporation rates based on given data.

   Hint

   How do these factors interact to reduce evaporation?

6. 6.

   Design a water management plan for a region prone to drought, incorporating all discussed techniques for minimizing reservoir evaporation. Include potential costs and benefits.

   Hint

   Think about how you can layer these strategies for the best effect.
