Challenge Problems
Push your limits with advanced challenges
Given a channel with a bottom width of 6 meters, discharge of 1.2 cubic meters per second, how would you determine the type of slope (mild, steep, or critical) based on your calculations involving critical depth?
💡 Hint: Follow through each step to relate the depth types.
How would changing the channel width affect the flow profiles if the discharge remains constant? Analyze the conditions of normal, mild, and steep slopes.
💡 Hint: Think through the effects of width and flow resistance.
