Duration given Extreme Rainfall Depth Solution

STEP 0: Pre-Calculation Summary

Formula Used

Duration of Excess Rainfall in Hours = (Extreme Rainfall Depth/42.16)^(1/0.475)
D = (P_m/42.16)^(1/0.475)
This formula uses 2 Variables

Variables Used

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.
Extreme Rainfall Depth - (Measured in Centimeter) - Extreme Rainfall Depth is the total rainfall depth during a given period, expressed in centimeters (cm).

STEP 1: Convert Input(s) to Base Unit

Extreme Rainfall Depth: 641.52 Millimeter --> 64.152 Centimeter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

D = (P_m/42.16)^(1/0.475) --> (64.152/42.16)^(1/0.475)

Evaluating ... ...

D = 2.41996831956215

STEP 3: Convert Result to Output's Unit

8711.88595042374 Second -->2.41996831956215 Hour (Check conversion here)

FINAL ANSWER

2.41996831956215 ≈ 2.419968 Hour <-- Duration of Excess Rainfall in Hours

(Calculation completed in 00.004 seconds)

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 vapour and fall under gravity. Fog and mist are not precipitation but suspensions.

What is Probable Maximum Precipitation (PMP)?

Probable maximum precipitation is defined as the estimate of the extreme maximum rainfall of a given duration that is physically possible over a basin under critical hydrological and meteorological conditions. This is used to compute flood by using suitable rainfall runoff model.
Two methods of PMP estimation are:
1. Statistical procedure
2. Meteorological approach
