Question 1

What is the main purpose of the W-index in hydrology?

  • To simplify runoff calculations
  • To account for initial losses
  • To represent rainfall intensity

💡 Hint: Think about what happens before water infiltrates.

Question 2

True or False: The W-index only works for rural areas.

  • True
  • False

💡 Hint: Consider the implications of urbanization.

Challenge Problems

Push your limits with challenges.

Question 1

In a storm event, total rainfall is found to be 120 mm, with an observed direct runoff of 50 mm, and initial losses estimated at 20 mm over a storm duration of 3 hours. Calculate the W-index and discuss the implications of initial losses on overall runoff estimation.

💡 Hint: Plug in the values into the W-index formula.

Question 2

Imagine a catchment area that experiences varying absorption rates due to different land uses. Discuss how this variation would affect the application of the W-index.

💡 Hint: Consider how land use influences infiltration characteristics.
