Recurrence Interval by California Method Solution

STEP 0: Pre-Calculation Summary

Formula Used

Recurrence Interval = Number of Years/Flood Serial Number
T_r = N_Years/m
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 = N_Years/m --> 10/3.3

Evaluating ... ...

T_r = 3.03030303030303

STEP 3: Convert Result to Output's Unit

3.03030303030303 --> No Conversion Required

FINAL ANSWER

3.03030303030303 ≈ 3.030303 <-- Recurrence Interval
