Question 1.
What is gradually varied flow?
Show hintHide hint
Consider the definition focusing on gradual changes.
Question 2.
What does the critical depth represent?
Show hintHide hint
Think about energy considerations.
3Question 3.
What is the equation used to calculate the rate of change of depth in gradually varied flow?
Show hintHide hint
Write out the complete equation mentioned in class.
4Question 4.
True or False: A normal depth greater than critical depth indicates a steep slope.
- True
- False
Show hintHide hint
Think about the slope definitions.
Question 5.
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?
Show hintHide hint
Follow through each step to relate the depth types.
Question 6.
How would changing the channel width affect the flow profiles if the discharge remains constant? Analyze the conditions of normal, mild, and steep slopes.
Show hintHide hint
Think through the effects of width and flow resistance.
