Question 1
What does the φ-index fail to account for?
💡 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.

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.
