Question 1
What characterizes confined aquifers?
- They are always dry
- They are under pressure
- They have no water
💡 Hint: Think about what keeps the water inside.
Question 2
True or False: The storage coefficient in confined aquifers is generally higher than in unconfined aquifers.
- True
- False
💡 Hint: Consider the mechanism behind water storage.

Challenge Problems
Push your limits with challenges.
Question 1
A confined aquifer has a storage coefficient of 0.0004. If the hydraulic head decreases by 4 meters, calculate the volume of water that would be released from a 1-hectare section of the aquifer.
💡 Hint: Use the formula for volume release of a confined aquifer.
Question 2
If a well tapping a confined aquifer results in a drawdown of 10 meters, and the aquifer has a transmissibility of 100 m²/day. Find out how long it would take for the water level to recover to original state if pumping stops.
💡 Hint: Analyze recovery data or graphically review recuperation tests for similar conditions.
