1. Construct a graph of exceedance probability using the methods outlined below. 2. The table shows an annual maximum series of 1-hour rainfall events. The amount of precipitation (Pep) during each 1-hour event is given in mm. Rank them from largest to smallest. Then calculate the $$p$$-value using the following equation: $$p=m/(n+1)$$ Where $$m$$ is equal to the ranked value and $$n$$ is the total number of records. The retum period or recurrence interval $$T$$ (years) is given by: $$T=1/p$$ Use the $$p$$ and the Pcp value to plot the recurrence interval on the extreme-value probability (Gumbel) paper provided. ( 3 marks) Questions: (1 mark each) 1. What is the probability that the I-hour precipitation will exceed $$50\mathrm{mm}$$ ? 2. What is the expected 1-hour precipitation of a '15 year storm"?
