return period calculation (hydrology analysis) 

Thank you. I have a question. how is it possible to have a different return point for the same depth of 19.2 mm?

What to do if two values have same rank

but doesn't the question ask for the frequency of receiving MORE than 23.4 mm?

Waalaikumussalam jazakalloh my sister

Where did you source the probability of occurance equation from?

Can u send me documents of this equations?

It seems the equation is not correct. Fa=(the rank of each event)/(number of data events+1)
