18.3.1. Water Resource Loss

Try these first

1. 1.

   Define reservoir evaporation.

   Hint

   What happens to water at the surface of a reservoir?

2. 2.

   List two economic implications of water loss due to evaporation.

   Hint

   How does losing water impact finances?

3. 3.

   What is reservoir evaporation?

   • A) Water lost from evaporation into the atmosphere
   • B) Water gained from precipitation
   • C) Water transferred to groundwater
   • D) Water stored behind dam walls

   Hint

   Think about what happens to water when it's exposed to air.

4. 4.

   True or False: Evaporation increases the concentration of minerals and salts in water.

   • True
   • False

   Hint

   Consider what happens to salt in a drying puddle.

5. 5.

   Given a reservoir with an annual evaporation of 1.5 m in a warm climate, estimate how much water is lost in cubic meters if the reservoir has a surface area of 10 hectares.

   Hint

   Remember to convert the area correctly before calculating.

6. 6.

   Discuss the potential long-term environmental impacts if reservoir evaporation is not managed effectively in a drought-prone region.

   Hint

   Consider the balance between water availability and ecological health.
