Challenge Problems
Push your limits with advanced challenges
During a storm, urban area P records total precipitation of 150 mm, with initial losses of 50 mm, resulting in 60 mm of runoff over a duration of 6 hr. Calculate the W-Index and discuss how it could affect city planning.
💡 Hint: Understand that high runoff could lead to flooding if the drainage isn't adequate.
In a rural area with P = 80 mm, initial losses of 10 mm, and Q = 20 mm, how does the W-Index compare to urban settings? Evaluate the implications.
💡 Hint: Think about how infiltration may vary greatly between urban and rural contexts.
