Question 1.
What type of data is necessary for developing IDF and DDF curves?
Show hintHide hint
Think about the duration of data required.
Question 2.
Name one distribution used for frequency analysis.
Show hintHide hint
It's a common method for extreme values.
3Question 3.
What is the IDF relationship used for?
- Determining rainfall volume
- Correlating rainfall intensity with storm duration
- Forecasting weather patterns
Show hintHide hint
Remember the relationship between intensity, duration, and frequency.
4Question 4.

- True
- False
Show hintHide hint
Think about the characteristics of different statistical distributions.
Question 5.
Given a dataset of rainfall in a region, derive the IDF curves using Gumbel Distribution. Explain the steps involved in your process.
Show hintHide hint
Focus on the distribution fitting process and parameter estimation.
Question 6.
A city needs to implement a new urban drainage system. Which curves would you recommend they use, and why?
Show hintHide hint
Consider how rainfall behavior affects urban drainage systems.
