Given a rank for a particular flood event of 25 and a record of 24 years duration, what is the recurrence
interval for a flood of this size? What will be an ideal response?
On the average, a flood of this size would be expected to occur once a year. This is calculated by
adding 1 to the duration of the record in years (24 + 1) and then dividing this result by the rank of the
event (25).
