Challenge Problems
Push your limits with advanced challenges
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.
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.
