Return Period given Maximum Intensity Solution

STEP 0: Pre-Calculation Summary
Formula Used
Return Period = ((Maximum Intensity*(Duration of Excess Rainfall in Hours+Coefficient a)^(Constant n))/Constant K)^(1/Coefficient x)
Tr = ((imax*(D+a)^(n))/K)^(1/x)
This formula uses 7 Variables
Variables Used
Return Period - Return Period [Years] is an average time or an estimated average time between events such as earthquakes, floods, landslides, or a river discharge flows to occur.
Maximum Intensity - (Measured in Centimeter per Hour) - Maximum Intensity is the ratio of the total amount of rain (rainfall depth) falling during a given period to the duration of the period.
Duration of Excess Rainfall in Hours - (Measured in Hour) - Duration of Excess Rainfall in Hours is time during which continuous rain is observed at a given point or within a given area or Excess Rainfall of the Unit Hydrograph used in deriving the S-curve.
Coefficient a - Coefficient a for Area represented by the Station or coefficient for International Passenger Forecast.
Constant n - Constant n is for the catchment to be determined by the effective rainfall of the catchment.
Constant K - Constant K is for the catchment to be determined by flood hydrograph characteristics of the catchment.
Coefficient x - Coefficient x for the Area represented by the catchment station under consideration.
STEP 1: Convert Input(s) to Base Unit
Maximum Intensity: 7 Centimeter per Hour --> 7 Centimeter per Hour No Conversion Required
Duration of Excess Rainfall in Hours: 2.42 Hour --> 2.42 Hour No Conversion Required
Coefficient a: 0.6 --> No Conversion Required
Constant n: 3 --> No Conversion Required
Constant K: 4 --> No Conversion Required
Coefficient x: 1.5 --> No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
Tr = ((imax*(D+a)^(n))/K)^(1/x) --> ((7*(2.42+0.6)^(3))/4)^(1/1.5)
Evaluating ... ...
Tr = 13.2446123510986
STEP 3: Convert Result to Output's Unit
13.2446123510986 --> No Conversion Required
FINAL ANSWER
13.2446123510986 13.24461 <-- Return Period

3 Maximum Intensity-Duration-Frequency Relationship Calculators

Duration given Maximum Intensity
Go Duration of Excess Rainfall in Hours = ((Constant K*(Return Period^Coefficient x)/Maximum Intensity)-Coefficient a^Constant n)^(1/Constant n)
Return Period given Maximum Intensity
Go Return Period = ((Maximum Intensity*(Duration of Excess Rainfall in Hours+Coefficient a)^(Constant n))/Constant K)^(1/Coefficient x)
Maximum Intensity in General Form
Go Maximum Intensity = (Constant K*Return Period^(Coefficient x))/(Duration of Excess Rainfall in Hours+Coefficient a)^(Constant n)

Return Period given Maximum Intensity Formula

Return Period = ((Maximum Intensity*(Duration of Excess Rainfall in Hours+Coefficient a)^(Constant n))/Constant K)^(1/Coefficient x)
Tr = ((imax*(D+a)^(n))/K)^(1/x)

What is Precipitation?

Precipitation is a form of water from the atmosphere. It is a term in meteorology, and includes rain, snow, sleet, ice pellets dew, frost, and hail. These form by condensation from atmospheric water vapor, and fall under gravity. Fog and mist are not precipitation but suspensions..
