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