Variability in the percentiles on log10 for the entire daily flow record.

Calculation Details

Compute the decimal logarithm of the daily flow values. Calculate the 5th, 10th, 15th, …, 95th percentiles of these log-transformed values. Calculate the standard deviation and the mean of the 19 percentile values. Multiply the former by 100 and divide the result by the latter.
