Interactive Quizzes
Engage in quick quizzes to reinforce what you've learned and check your comprehension.
Question 1
What does the φ-index represent?
- A constant infiltration rate during storms
- Average rate of infiltration equating excess rainfall to runoff
- Initial loss during infiltration
💡 Hint: Focus on what φ relates to in terms of average performance.
Question 2
True or False: The W-index can calculate runoff even when initial losses are unknown.
- True
- False
💡 Hint: Consider the role of initial conditions.

Challenge Problems
Push your limits with challenges.
Question 1
Given a rainfall of 200 mm and a direct runoff of 80 mm over 4 hours, calculate the φ-index, and discuss how accurate this representation is under different conditions.
💡 Hint: Focus on how rainfall duration impacts the infiltration capability.
Question 2
Provide a detailed plan for selecting between φ-index and W-index for a proposed urban drainage system, considering local conditions.
💡 Hint: Think about local land cover, vegetation, and recent rainfall history.
