13.10. Limitations and Uncertainty in IDF/DDF Analysis

Try these first

1. 1.

   What is meant by 'data quality'?

   Hint

   Consider how we assess data reliability.

2. 2.

   Why do longer records improve hydrological predictions?

   Hint

   Think about rare events.

3. 3.

   What is a major challenge to the assumption of stationarity in rainfall records?

   • Climate change
   • Consistent weather patterns
   • Improved data collection

   Hint

   Think about recent weather extremes.

4. 4.

   True or False: Urbanization reduces the effectiveness of IDF curves.

   • True
   • False

   Hint

   Consider how cities handle stormwater.

5. 5.

   Evaluate how a city with insufficient rainfall records might prepare for unexpected floods. Discuss potential strategies.

   Hint

   Consider what resources would help them improve data.

6. 6.

   Discuss how you would advise local authorities about the implications of climate change on existing hydrological models.

   Hint

   Think about the importance of flexibility in planning.
