35.3.3. Depth of Saturation

Try these first

1. 1.

   What is specific yield?

   Hint

   Think about how much water can be extracted from aquifers.

2. 2.

   How does deeper saturation affect water drainage?

   Hint

   Consider gravity's role in drainage.

3. 3.

   What happens to specific yield when saturation depth increases?

   • It decreases
   • It remains the same
   • It increases

   Hint

   Consider the role of gravity in deeper saturation.

4. 4.

   True or False: Water held in micropores at shallow depths is more likely to drain under gravity.

   • True
   • False

   Hint

   Reflect on how gravity influences water movement.

5. 5.

   Calculate the change in specific yield if the depth of saturation increases from 5 m to 10 m, knowing that specific yield increases linearly with depth at the site observed.

   Hint

   Use linearity to determine the yield change over established depths.

6. 6.

   Evaluate how introducing finer grain sizes to an aquifer at depths of 5 m and 10 m would affect specific yield if previously observed rates were 25% and 30%.

   Hint

   Reflect on how different soil types impact water drainage.
