Recurrence Interval by Hazen's Method Solution

STEP 0: Pre-Calculation Summary

Formula Used

Recurrence Interval = (2*Number of Years)/(2*Flood Serial Number-1)
T_r = (2*N_Years)/(2*m-1)
This formula uses 3 Variables

Variables Used

Recurrence Interval - Recurrence Interval is an average time or an estimated average time.
Number of Years - Number of Years is defined as the time span in year for which rainfall had occur.
Flood Serial Number - Flood Serial Number is the constant number used in calculation.

STEP 1: Convert Input(s) to Base Unit

Number of Years: 10 --> No Conversion Required
Flood Serial Number: 3.3 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

T_r = (2*N_Years)/(2*m-1) --> (2*10)/(2*3.3-1)

Evaluating ... ...

T_r = 3.57142857142857

STEP 3: Convert Result to Output's Unit

3.57142857142857 --> No Conversion Required

FINAL ANSWER

3.57142857142857 ≈ 3.571429 <-- Recurrence Interval
