Recurrence Interval Solution

STEP 0: Pre-Calculation Summary

Formula Used

Recurrence Interval = 100/Flood Frequency
T_r = 100/F
This formula uses 2 Variables

Variables Used

Recurrence Interval - Recurrence Interval refers to the average time between events like floods or storms of a specific intensity, typically measured in years.
Flood Frequency - The Flood Frequency refers to the likelihood or recurrence interval of floods of a specific magnitude occurring in a given area over time.

STEP 1: Convert Input(s) to Base Unit

Flood Frequency: 33.3 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

T_r = 100/F --> 100/33.3

Evaluating ... ...

T_r = 3.003003003003

STEP 3: Convert Result to Output's Unit

3.003003003003 --> No Conversion Required

FINAL ANSWER

3.003003003003 ≈ 3.003003 <-- Recurrence Interval

What is Return Period ?

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.

How to Calculate Recurrence Interval?

Recurrence Interval calculator uses Recurrence Interval = 100/Flood Frequency to calculate the Recurrence Interval, The Recurrence Interval is defined as the average time or an estimated average time between events such as earthquakes, floods, landslides, or a river discharge flows to occur. Recurrence Interval is denoted by T_r symbol.

How to calculate Recurrence Interval using this online calculator? To use this online calculator for Recurrence Interval, enter Flood Frequency (F) and hit the calculate button. Here is how the Recurrence Interval calculation can be explained with given input values -> 4 = 100/33.3.

FAQ

What is Recurrence Interval?

The Recurrence Interval is defined as the average time or an estimated average time between events such as earthquakes, floods, landslides, or a river discharge flows to occur and is represented as T_r = 100/F or Recurrence Interval = 100/Flood Frequency. The Flood Frequency refers to the likelihood or recurrence interval of floods of a specific magnitude occurring in a given area over time.

How to calculate Recurrence Interval?

The Recurrence Interval is defined as the average time or an estimated average time between events such as earthquakes, floods, landslides, or a river discharge flows to occur is calculated using Recurrence Interval = 100/Flood Frequency. To calculate Recurrence Interval, you need Flood Frequency (F). With our tool, you need to enter the respective value for Flood Frequency and hit the calculate button. You can also select the units (if any) for Input(s) and the Output as well.

How many ways are there to calculate Recurrence Interval?

In this formula, Recurrence Interval uses Flood Frequency. We can use 3 other way(s) to calculate the same, which is/are as follows -

Recurrence Interval = Number of Years/Flood Serial Number
Recurrence Interval = (2*Number of Years)/(2*Flood Serial Number-1)
Recurrence Interval = Number of Years/(Flood Serial Number+Gumbel Correction-1)
