Challenge Problems
Push your limits with advanced challenges
Consider an unconfined aquifer with a specific yield of 0.3. If the area of influence during pumping is 1000 m² and the water table declines by 5 meters, how much water is released in cubic meters?
💡 Hint: Use the water release formula carefully.
Analyze the impact of a new agricultural policy that encourages deep well pumping in an area noted for clay soil, known to have a typically low specific yield. How might this affect the local aquifer sustainability?
💡 Hint: Think about the implications of excessive water extraction on ecosystems and water levels.
