Challenge Problems
Push your limits with advanced challenges
Design a detention basin for a small urban area expected to receive intense rainfall. What key factors will influence your design and how would you use DDF curves to guide your decision?
💡 Hint: Consider both the volume of rainfall and the duration when utilizing DDF curves.
Evaluate a hypothetical urban drainage system that failed during a recent storm. How might the use of IDF curves in its design be inadequate in light of changing rainfall patterns due to climate change?
💡 Hint: Think about how climate change might influence rainfall intensity and frequency.
