For the annual maximum flood peaks for the River Taff given, determine the index flood QMED and the standard deviation. If the peaks fit a Gumbel distribution, calculate the 100-yr and the 1000-yr floods for Pontypridd. Take a = 0.0123; u = 308 m3/s
(QMED = 337.8 m3/s; S = 104.2 m3/s, Q100 = 681.996m3/s, Q1000 = 869.6m3/s)
(QMED = 337.8 m3/s; S = 104.2 m3/s, Q100 = 681.996m3/s, Q1000 = 869.6m3/s)
