Show hintHide hint
What aspect does it not consider?
3Question 3.
What does the Φ-index measure?
- Only rainfall
- Average water loss due to infiltration

- True
- False

Think about how it's defined.
Question 5.
Given a rainfall event of 200 mm and an estimated Φ-index of 80 mm, calculate the runoff. Discuss the implications if this estimate is incorrect.
Show hintHide hint
Focus on the calculation first and then reason through consequences.
Question 6.
During a rainfall event, the W-index starts at 50 mm and drops to 30 mm by the end. Discuss how continuous changes in the W'-index can affect water resource planning.
