Question 2 3 pts Estimate the total excess/effective rainfall in mm for a 5% AEP storm. The temporal pattern distribution (in %) for a 45-min rainfall duration (5-min time step) for a South Australian catchment is given below. 13.18 9.3 9.3 13.18 20.93 13.95 13.18 20.93 13.95 4.65 8.53 6.98 Consider: Total rainfall depth = 26.2 mm IL = 7.8 mm and CL = 2.6 mm/hr Give your answer to two decimal places. Note: When presenting your answers, round your answer as instructed, but for your calculation, use as many decimal places as you have to avoid rounding errors.
