Calculate Flood/Rainfall Frequency from cumulative distribution function (CDF) of the distribution

Specifically, we will use the cumulative distribution function (CDF) of the fitted distribution to calculate the annual exceedance probability (AEP), or the probability that the event is equaled or exceeded in any single year. For example, considering a 200,000 cfs … Continue reading
