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

STEP 0: Pre-Calculation Summary

Formula Used

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

Variables Used

Number of Years - Number of Years refers to the time span in year for which rainfall had occur.
Recurrence Interval - Recurrence Interval refers to the average time between events like floods or storms of a specific intensity, typically measured in years.
Flood Serial Number - Flood serial number refers to specific flood events in a chronological record, aiding in historical analysis.

STEP 1: Convert Input(s) to Base Unit

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

STEP 2: Evaluate Formula

Substituting Input Values in Formula

N_Years = (T_r*(2*m-1))/2 --> (3*(2*3.3-1))/2

Evaluating ... ...

N_Years = 8.4

STEP 3: Convert Result to Output's Unit

8.4 --> No Conversion Required

FINAL ANSWER

8.4 <-- Number of Years

(Calculation completed in 00.020 seconds)

Flood Serial Number given Recurrence Interval by California Method

Go Flood Serial Number = Number of Years/Recurrence Interval

Number of Years given Recurrence Interval by California Method

Go Number of Years = Recurrence Interval*Flood Serial Number

Recurrence Interval by California Method

Go Recurrence Interval = Number of Years/Flood Serial Number

Recurrence Interval

Go Recurrence Interval = 100/Flood Frequency

Number of Years given Recurrence Interval by Hazen's Method Formula

Number of Years = (Recurrence Interval*(2*Flood Serial Number-1))/2
N_Years = (T_r*(2*m-1))/2

What is recurrence interval ?

A return period, also known as a recurrence interval or repeat interval, is an average time or an estimated average time between events such as earthquakes, floods, landslides, or a river discharge flows to occur.
