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)
T_r = ((i_max*(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.
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: 266.794 Centimeter per Hour --> 266.794 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

T_r = ((i_max*(D+a)^(n))/K)^(1/x) --> ((266.794*(2.42+0.6)^(3))/4)^(1/1.5)

Evaluating ... ...

T_r = 150.000001692903

STEP 3: Convert Result to Output's Unit

150.000001692903 --> No Conversion Required

FINAL ANSWER

150.000001692903 ≈ 150 <-- Return Period

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..
