Practice Questions

Test your understanding with targeted questions related to the topic.

Question 1

Easy

Define φ-Index.

💡 Hint: Think about the conditions under which runoff is initiated.

Question 2

Easy

What does W-Index account for?

💡 Hint: Consider what happens to rainwater before it contributes to runoff.

Question 1

What does the φ-Index represent?

  • A constant infiltration rate
  • Rainfall rate when runoff starts
  • Total rainfall amount

💡 Hint: Think about how rainfall affects runoff initiation.

Question 2

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

  • True
  • False

💡 Hint: Recall the purpose of using W-Index.

Challenge Problems

Push your limits with challenges.

Question 1

During a heavy rain event, the total precipitation measured 100 mm, with a runoff of 30 mm after 5 hours. Calculate φ and W indices and discuss the implications of your findings.

💡 Hint: Apply the formulas and interpret the findings in the context of hydrology.

Question 2

A scenario describes a storm with 70 mm of rain, but saturation means only 20 mm is effectively utilized for infiltration with runoff measured at 10 mm. Calculate the W and Wᵐᶦⁿ indices, explaining the environmental conditions leading to those values.

💡 Hint: Make sure to consider how factors like saturation impact infiltration metrics.
