Based on the 100-year rainfall records at a certain location in a city, the rainfall intensities with an annual exceedance probability of 0.1 (10-year return period) of different duration are given below. Duration, td (min) 15 30 60 120 Intensity, i (mm/h) 161 132 103 74 a) Determine the coefficients a and c for the following intensity-duration-frequency (IDF) curve using the least-squares method: , in which i
