Question 1.
What does the flow-duration curve represent?
Show hintHide hint
Consider what the axes of the graph might show.
Question 2.
What does a flatter curve indicate?
Show hintHide hint
Think about the stability of water supply.
3Question 3.
What does an FDC plot represent?
- Water quality over time
- Flow rates equaled or exceeded
- Drought occurrences
Show hintHide hint
Focus on what the curve's main purpose is.
4Question 4.
True or False: A steeper FDC implies more stable flow conditions.
- True
- False
Show hintHide hint
Think about the characteristics of steep versus flat curves.
Question 5.
Given a hypothetical river's FDC, calculate the average flow rate during the 70% exceedance level and explain its significance.
Show hintHide hint
Look for the flow value where 70% intersects the curve.
Question 6.
Discuss the implications of steep versus flat FDCs on ecosystems and human usage. How would you balance both?
Show hintHide hint
Think about compromises and resource management strategies.
