The skewness of the log10 flood discharge (G) is 0.2.
A) What is the 100-year flood discharge (m3/s) and its 90%
confidence limits.
B)Estimate the 1-in-100 year flood discharge (m3/s) for a
catchment using the
probabilistic rational method of Pilgrim and McDermott. The
catchment is located near
Newcastle NSW, Australia. Its size is 50 km2, and its maximum
elevation is less than 400 m height.
The runoff coefficient C10 is 0.35.
