Find the design intensity for the 1-hour and 50-year storm that will be used to design the storm sewers of the Sacramento Metropolitan airport expansion using: a. Caltrans-DWR IDF curve approach Perform the calculations by hand Use the tables to check your work.
b. Use the TP-40 website and compare to your findings in part 1.
c. Based on the NRCS 24-hour, what is the expected rainfall distribution.
4. Determine the probability of exceedence in the first 10-years 16 77.
5. Determine the risk of failure of the designed storm sewer in the expected 50-year of the project life.
