18.6.1. Indira Sagar Reservoir (Madhya Pradesh)

Try these first

1. 1.

   What is the estimated annual evaporation loss at the Indira Sagar Reservoir?

   Hint

   Think about the number mentioned in the context of evaporation.

2. 2.

   What method is commonly used to estimate evaporation?

   Hint

   Recall the name of the method mentioned for estimation.

3. 3.

   What is the estimated annual evaporation loss from the Indira Sagar Reservoir?

   • 1.5 m
   • 2.3 m
   • 3.0 m

   Hint

   Look for the specific number mentioned in the description.

4. 4.

   True or False: Windbreaks can increase evaporation rates.

   • True
   • False

   Hint

   Consider the purpose of windbreaks discussed.

5. 5.

   If the total water capacity of the Indira Sagar Reservoir is 500 million cubic meters and the annual evaporation loss is 2.3 m, calculate the total volume of water lost annually due to evaporation.

   Hint

   Consider how to calculate volume based on area and height.

6. 6.

   Evaluate the cost implications of implementing windbreaks and floating solar panels in the Indira Sagar Reservoir. Assume the costs for these implementations and compare them with the potential long-term savings from reduced evaporation losses.

   Hint

   Factor in both one-time costs and annual savings in water and energy.
