Rainfall intensity and urban drain sizing
Analyse rainfall records to find design storms and size a storm drain for a colony.
The brief
Drains designed for ordinary rain flood in heavy storms. From long daily and hourly rainfall records, build intensity-duration-frequency curves, choose a design storm, estimate runoff with the rational method, and size the drain for a small colony. Good looks like: fitted extreme-value statistics, an IDF chart, hand calculations that check the code, and a drain size with a safety margin.
What you will build
- Collect rainfall records for a city
- Extract annual maximum rainfall for several durations
- Fit extreme value distributions
- Build IDF curves
- Estimate runoff by the rational method
- Size the drain and write the design note
