Question 1

What does porosity measure?

  • Total void space
  • Water yield
  • Water retention

💡 Hint: Think about the space available for water storage.

Question 2

True or False: Specific yield is the same as porosity.

  • True
  • False

💡 Hint: Recall the definitions of both terms.

Challenge Problems

Push your limits with challenges.

Question 1

An aquifer has a porosity of 0.35, and its particles are mainly composed of fine sand that retains a significant amount of water through adhesion. Analyze what this means for both specific yield and specific retention.

💡 Hint: Consider what 'fine sand' characteristics indicate about its ability to yield water.

Question 2

If you have an aquifer with a porosity of 0.40 and you find through experimentation that it has a specific retention of 0.10, how would you evaluate its potential for sustainable yield, discussing possible scenarios?

💡 Hint: Think about how much water is available and needed to maintain the ecosystem.
