Challenge Problems
Push your limits with advanced challenges
Imagine you have historical storm data showing a 150mm rainfall over a 5 km² area in 1 hour. Using the DAD relationship, predict the rainfall depth for a 50 km² area during the same time frame.
💡 Hint: Apply the concept that as the area increases, the depth decreases.
Given a set of DAD curves for different storm types, analyze how the type of storm alters the relationship between area and depth, and recommend design considerations for a new dam.
💡 Hint: Consider the characteristics of the analyzed storms.
