Challenge Problems

Push your limits with challenges.

Question 1

Given a new channel design with a complex shape (dimensions provided), calculate the n value range based on materials used and predict the flow outcomes.

💡 Hint: Reference material charts for n values and remember to account for their impact on flow.

Question 2

Analyze how seasonal changes in a channel (e.g., sediment buildup, vegetation growth) can affect the n value and flow rates over time.

💡 Hint: Consider external factors affecting channel dynamics.
