Test your understanding with targeted questions related to the topic.

Question 1

Easy

What does the φ-index represent?

💡 Hint: Think about how rainfall exceeds what can be absorbed.

Question 2

Easy

Name a factor that the W-index considers that the φ-index does not.

Interactive Quizzes

Engage in quick quizzes to reinforce what you've learned and check your comprehension.

Question 1

What does the φ-index fail to account for?

  • Initial abstraction
  • Cumulative infiltration
  • Runoff volume

💡 Hint: Think about what happens before water begins to infiltrate.

Question 2

True or False: The W-index gives a more accurate representation of infiltration by including initial losses.

  • True
  • False

💡 Hint: Recall the definition of the W-index.

Challenge Problems

Push your limits with challenges.

Question 1

During a heavy storm, you total 100 mm of rainfall over 5 hours, with an observed runoff of 40 mm and initial abstraction of 15 mm. Calculate the φ-index and W-index.

💡 Hint: Use the relevant formulas for each index.

Question 2

Consider a scenario where you have a test catchment with a varying rainfall and runoff pattern. How would you analyze which infiltration index to use, based on historical data?

💡 Hint: Identify the data characteristics and storm behavior.
