The probability for the annual maximum flood magnitude to occur = \(\frac{1}{{Return\;period\;}} \)
Calculation:
Given,
Return period T = 10 years
n = 5 years
p is the probability of occurring an event
q is the probability of not occurring an invent.
\(\begin{array}{l} p = \frac{1}{T} = 0.1\\ q = 1 - p = 0.9 \end{array}\)
Probability of flood at least once in next 5 years
= 1 – no flood in next 5 years
= 1 – q5
= 1 – (0.9)5 = 0.40Last updated on May 28, 2025
