The IDF function for 10-yr storms in Santa Fe, New Mexico, is given by i=\frac{818}{(t+8.54)^{0.76}} \mathrm{~mm} / \mathrm{h} where i is the average intensity in mm/h and t is the

duration in minutes. Assuming that the maximum rainfall intensity occurs at 44% of the rainfall duration, estimate the triangular hyetograph for a 50-min storm.
