Number of Years given Recurrence Interval by Gumbel's Method Solution

STEP 0: Pre-Calculation Summary

Formula Used

Number of Years = Recurrence Interval*(Flood Serial Number+Gumbel Correction-1)
N_Years = T_r*(m+C_g-1)
This formula uses 4 Variables

Variables Used

Number of Years - Number of Years is defined as the time span in year for which rainfall had occur.
Recurrence Interval - Recurrence Interval is an average time or an estimated average time.
Flood Serial Number - Flood Serial Number is the constant number used in calculation.
Gumbel Correction - Gumbel Correction is the constant quantity depend on the m/N ratio.

STEP 1: Convert Input(s) to Base Unit

Recurrence Interval: 3 --> No Conversion Required
Flood Serial Number: 3.3 --> No Conversion Required
Gumbel Correction: 1.03333 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

N_Years = T_r*(m+C_g-1) --> 3*(3.3+1.03333-1)

Evaluating ... ...

N_Years = 9.99999

STEP 3: Convert Result to Output's Unit

9.99999 --> No Conversion Required

FINAL ANSWER

9.99999 <-- Number of Years
