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
Exceedance Probability
Introduction Sometimes a hydrologist may need to know what the chances are over a given time period that a flood will reach or exceed a specific magnitude. This is called the probability of occurrence or the exceedance probability. Let’s say … Continue reading
