Precipitation given Total Runoff Depth for Practical Use Solution

STEP 0: Pre-Calculation Summary

Formula Used

Total Storm Precipitation = Total Direct Runoff+(Φ-Index*Duration of Rainfall Excess)
P = R_d+(φ*t_e)
This formula uses 4 Variables

Variables Used

Total Storm Precipitation - (Measured in Centimeter) - Total Storm Precipitation is the annual precipitation of the current year.
Total Direct Runoff - (Measured in Centimeter) - Total Direct Runoff is the runoff entering stream channels promptly after rainfall or snowmelt.
Φ-Index - Φ-Index of a catchment is the constant infiltration capacity that would yield the actual total runoff for a given rainfall amount.
Duration of Rainfall Excess - (Measured in Hour) - Duration of Rainfall Excess is the total time in which the rainfall intensity the greater than the average rate of infiltration (in hours).

STEP 1: Convert Input(s) to Base Unit

Total Direct Runoff: 117.88 Centimeter --> 117.88 Centimeter No Conversion Required
Φ-Index: 0.0279 --> No Conversion Required
Duration of Rainfall Excess: 4 Hour --> 4 Hour No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

P = R_d+(φ*t_e) --> 117.88+(0.0279*4)

Evaluating ... ...

P = 117.9916

STEP 3: Convert Result to Output's Unit

1.179916 Meter -->117.9916 Centimeter (Check conversion here)

FINAL ANSWER

117.9916 Centimeter <-- Total Storm Precipitation

(Calculation completed in 00.004 seconds)

Precipitation given Total Runoff Depth for Practical Use

Go Total Storm Precipitation = Total Direct Runoff+(Φ-Index*Duration of Rainfall Excess)

Duration of Rainfall Excess given Total Runoff Depth

Go Duration of Rainfall Excess = (Total Storm Precipitation-Total Direct Runoff)/Φ-Index

Phi Index given Total Runoff Depth

Go Φ-Index = (Total Storm Precipitation-Total Direct Runoff)/Duration of Rainfall Excess

Total Direct Runoff Depth

Go Total Direct Runoff = Total Storm Precipitation-(Φ-Index*Duration of Rainfall Excess)

Runoff to Determine Phi Index for Practical Use

Go Runoff in Cm from 24h Rainfall = Coefficient Depending on Soil Type*Intensity of Rainfall^1.2

Rainfall Intensity for Phi Index of Practical Use

Go Intensity of Rainfall = (Φ-Index*24)+Runoff in Cm from 24h Rainfall

Runoff for Phi Index for Practical Use

Go Runoff in Cm from 24h Rainfall = Intensity of Rainfall-(Φ-Index*24)

Phi Index for Practical Use

Go Φ-Index = (Intensity of Rainfall-Runoff in Cm from 24h Rainfall)/24

Pulses of Time Interval from Rainfall Hyetograph

Go Pulses of Time Interval = Duration/Time Interval

Duration of Rainfall from Rainfall Hyetograph

Go Duration = Pulses of Time Interval*Time Interval

Time Interval of Rainfall Hyetograph

Go Time Interval = Duration/Pulses of Time Interval

Precipitation given Total Runoff Depth for Practical Use Formula

Total Storm Precipitation = Total Direct Runoff+(Φ-Index*Duration of Rainfall Excess)
P = R_d+(φ*t_e)

What is Precipitation?

Precipitation is any product of the condensation of atmospheric water vapor that falls under gravitational pull from clouds. The main forms of precipitation include drizzling, rain, sleet, snow, ice pellets, graupel and hail.

What is Runoff?

Runoff is the flow of water occurring on the ground surface when excess rainwater, storm water, meltwater, or other sources, can no longer sufficiently rapidly infiltrate in the soil.
