Question 1.
Define gradually varied flow.
Show hintHide hint
Think about how slope relates to flow depth.
Question 2.
What is one assumption of gradually varied flow?
Show hintHide hint
Consider the shape of the channel.
3Question 3.
What characterizes gradually varied flow?
- A high slope
- Steady changes in depth
- Rapid depth changes
Show hintHide hint
Remember the definition of the flow.
4Question 4.
True or False: In a prismatic channel, the cross-sectional shape can vary.
- True
- False
Show hintHide hint
Focus on what 'prismatic' means.
Question 5.
Given a prismatic channel with a slope S0 of 0.01, determine the depth of flow y0 if Manning's n equals 0.03, Q is 20 m^3/s, and the channel width is 2m. Use the Manning equation for calculations.
Show hintHide hint
Start with the Manning equation to determine the velocity.
Question 6.
Describe the behavior of water flow in a channel that has an adverse slope and a critical depth equal to the normal depth. What happens to the flow?
Show hintHide hint
Consider how slope affects flow behavior.
