What is one method to reduce evaporation in reservoirs?
Think of changes that affect how much surface area is exposed.
What does desilting involve?
Consider what would change the shape or depth of the water.
What is the primary benefit of deepening a reservoir?
Think about what reduces water loss.
True or False: Deepening a reservoir only has benefits and no drawbacks.
Consider the practicalities of implementing this method.
You have a reservoir with a current depth of 10 feet and surface area of 100 acres. If deepening it to 20 feet reduces evaporation by 30%, what will be your new estimated evaporation loss if the initial loss was 1000 cubic feet?
Calculate the loss percentage and subtract it from the initial loss.
Evaluate a scenario where two reservoirs are adjacent, one deepened and the other not. After one year, the deeper reservoir saved 5000 liters compared to the shallow reservoir. What is the average daily water conservation difference if one reservoir evaporation reduced from 200 liters/day?
Divide the yearly savings by the number of days to find the average.
