16.7. Application in Water Resources Engineering

Try these first

1. 1.

   What is evaporation?

   Hint

   Think about how the water you leave out on a sunny day can disappear.

2. 2.

   Why is understanding evaporation important for farmers?

   Hint

   Consider how much water a plant needs to grow.

3. 3.

   What is the primary reason that evaporation studies are important in reservoir design?

   • To assess annual losses
   • To increase surface area
   • To reduce evaporation

   Hint

   Think about why you would want to know how much water your reservoir loses.

4. 4.

   True or False: Evaporation studies can assist in planning for drought.

   • True
   • False

   Hint

   Consider how loss of water affects dry periods.

5. 5.

   Given a reservoir has an annual evaporation rate of 400 mm, and the average precipitation is 800 mm, determine the net water gain or loss for the reservoir. How would this influence design considerations?

   Hint

   Think about the balance between water coming in and going out.

6. 6.

   If climate models predict increased temperatures leading to a 20% rise in evaporation rates, how should water resource managers adjust their strategies?

   Hint

   Think about adjustments that ensure there is enough water for demand.
