A Log Pearson III distribution was fitted to a 45-year record of annual maximum floods (or flood peaks). The mean of the natural log of the flood peaks is 4.8. a) (7 min) Determine the skewness and the standard deviation of the natural log of the flood peaks, if the flood peak for an ARI = 5 years was estimated to be 223 m³/s using a log Pearson distribution frequency factor of K5= 0.758. b) (7 min) Determine the ARI for a flood peak of 1364.3 m³/s. c) (8 min) Determine the 5% and 95% confidence limits for the flood discharge with ARI= 100 years.
