For example, a 1% annual exceedance probability of a \$100m loss compounds to 9.6% (1−0.910) probability over 10 years.

Webwhere P is the probability of exceedance, N is the number of years in the record that have flows greater than the flow of interest, and M is the total number of years in the record. For example, to find the peak flow of the 100 year flood, we need to find the flow that has a probability of exceedance of 1/100 or 0.01 in any given year.
