Question 1.
What does the W min-index represent?
Show hintHide hint
Think about rainfall events and their impact on soil.
Question 2.
Why is the W min-index important for urban planning?
Show hintHide hint
Consider the connections between runoff and drainage.
3Question 3.
What is the main purpose of the W min-index?
- Estimate minimum runoff
- Calculate average rainfall
- Represent minimum infiltration rate
Show hintHide hint
Think about what it measures.
4Question 4.
True or False: The W min-index accounts for initial losses.
- True
- False
Show hintHide hint
Remember the differences between the two indices.
Question 5.
A region experiences an intense rainfall of 120 mm, 50 mm of which results in runoff, with initial losses recorded at 15 mm. Calculate the W min-index and discuss the implications for urban design.
Show hintHide hint
Follow the formula step by step.
Question 6.
Discuss how variations in soil type might affect the W min-index in designing stormwater systems in contrasting areas.
Show hintHide hint
Consider soil properties and their influence on water movement.
