36.2.2. In Unconfined Aquifers

Try these first

1. 1.

   Define an unconfined aquifer.

   Hint

   Think about the layers of soil and rock above the aquifer.

2. 2.

   What is the typical storage coefficient range for unconfined aquifers?

   Hint

   Recall the specific yield concept while answering.

3. 3.

   What is the storage coefficient range for unconfined aquifers?

   • 0.01 - 0.05
   • 0.1 - 0.3
   • 0.5 - 0.8

   Hint

   Think about the values mentioned in class.

4. 4.

   True or False: Unconfined aquifers are impacted directly by surface conditions.

   • True
   • False

   Hint

   Consider how water moves in these aquifers.

5. 5.

   Given a storage coefficient of 0.25 for an unconfined aquifer, calculate the volume of water that can be sustainably extracted from an area of 1000 square meters for 1 meter of drawdown.

   Hint

   Remember to apply the formula for volume based on area.

6. 6.

   Discuss the impact of a sudden drought on a local agriculture dependent on unconfined aquifers and suggest management strategies to cope with such a situation.

   Hint

   Think about both immediate and long-term management strategies.
