Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

A watershed has a Curve Number of 80 and receives 100 mm of rain. Calculate the runoff. Discuss the implications for flood risk management.

💡 Hint: Apply the Curve Number method step-by-step.

Challenge 2 Hard

Compare the runoff calculations for two watersheds: one with a CN of 60 (forest) and the other with a CN of 90 (urban) under the same rainfall of 50 mm. Analyze the results.

💡 Hint: Use the differences in CN to highlight runoff disparities.
