Extreme Rainfall Depth Solution

STEP 0: Pre-Calculation Summary

Formula Used

Extreme Rainfall Depth = 42.16*Duration of Excess Rainfall in Hours^0.475
P_m = 42.16*D^0.475
This formula uses 2 Variables

Variables Used

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

STEP 1: Convert Input(s) to Base Unit

Duration of Excess Rainfall in Hours: 2.42 Hour --> 2.42 Hour No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

P_m = 42.16*D^0.475 --> 42.16*2.42^0.475

Evaluating ... ...

P_m = 64.1523989181647

STEP 3: Convert Result to Output's Unit

0.641523989181647 Meter -->641.523989181647 Millimeter (Check conversion here)

FINAL ANSWER

641.523989181647 ≈ 641.524 Millimeter <-- Extreme Rainfall Depth

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
