Question 1

What does φ-index represent?

  • Initial losses
  • Average rate of infiltration
  • Total runoff

💡 Hint: Consider what we discussed about its definition.

Question 2

The W-index accounts for initial losses. True or False?

  • True
  • False

💡 Hint: Remember the key difference between the two indices.

Challenge Problems

Push your limits with challenges.

Question 1

Given a storm event with 150mm of rainfall, where 90mm of runoff was recorded and initial losses measured to be 30mm, calculate both the φ-index and W-index.

💡 Hint: Use the formulas correctly and think about each component.

Question 2

Design a scenario where using φ-index would mislead stormwater management in a town. Discuss the outcomes if W-index were used instead.

💡 Hint: Consider the importance of initial losses in real-world applications.
