Practice Questions

Test your understanding with targeted questions related to the topic.

Question 1

Easy

What is specific yield?

💡 Hint: Think about how much water can be used compared to the total amount.

Question 2

Easy

Is specific yield found in confined or unconfined aquifers?

💡 Hint: Remember how water is held in confined aquifers.

Question 1

What does specific yield measure?

  • Total volume of aquifer
  • Volume of water that drains due to gravity
  • Water retention capacity

💡 Hint: Focus on how gravity influences available water.

Question 2

Is specific yield higher in sand compared to clay?

  • True
  • False

💡 Hint: Consider the characteristics of different soil types.

Challenge Problems

Push your limits with challenges.

Question 1

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.

Question 2

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.
