Runoff Coefficient given W-Index Solution

STEP 0: Pre-Calculation Summary

Formula Used

Runoff Coefficient = Rainfall Depth in Centimeters-(W-Index*Duration of Rainfall)
C_r = P_cm-(W*t_r)
This formula uses 4 Variables

Variables Used

Runoff Coefficient - Runoff Coefficient is a dimensionless coefficient relating the amount of runoff to the amount of precipitation received.
Rainfall Depth in Centimeters - (Measured in Meter) - Rainfall Depth in Centimeters is the total amount of rain falling over a catchment area in terms of depth.
W-Index - W-Index is the average infiltration rate during the time when the rainfall intensity exceeds the infiltration rate.
Duration of Rainfall - (Measured in Meter per Second) - Duration of Rainfall indicates how long the rainfall event lasted.

STEP 1: Convert Input(s) to Base Unit

Rainfall Depth in Centimeters: 10 Centimeter --> 0.1 Meter (Check conversion here)
W-Index: 2.01 --> No Conversion Required
Duration of Rainfall: 20 Centimeter per Hour --> 5.55555555555556E-05 Meter per Second (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

C_r = P_cm-(W*t_r) --> 0.1-(2.01*5.55555555555556E-05)

Evaluating ... ...

C_r = 0.0998883333333333

STEP 3: Convert Result to Output's Unit

0.0998883333333333 --> No Conversion Required

FINAL ANSWER

0.0998883333333333 ≈ 0.099888 <-- Runoff Coefficient

Runoff Coefficient given W-Index

Go Runoff Coefficient = Rainfall Depth in Centimeters-(W-Index*Duration of Rainfall)

W-Index given Duration of Rainfall

Go W-Index = (Precipitation-Runoff Volume)/Duration of the Rainfall

Duration of Rainfall given W-Index

Go Duration of the Rainfall = (Precipitation-Runoff Volume)/W-Index

Precipitation given W-Index

Go Precipitation = (W-Index*Duration of the Rainfall)+Runoff Volume

Runoff given W-Index

Go Runoff Volume = Precipitation-(W-Index*Duration of the Rainfall)

W-Index given Runoff Coefficient

Go W-Index = Intensity of Rainfall*(1-Runoff Coefficient)

Runoff Coefficient given W-Index Formula

Runoff Coefficient = Rainfall Depth in Centimeters-(W-Index*Duration of Rainfall)
C_r = P_cm-(W*t_r)

What is Evaporation Loss ?

Evaporation loss refers to the amount of liquid substance lost to the atmosphere through the process of vaporization, typically occurring at the liquid's surface.

How to Calculate Runoff Coefficient given W-Index?

Runoff Coefficient given W-Index calculator uses Runoff Coefficient = Rainfall Depth in Centimeters-(W-Index*Duration of Rainfall) to calculate the Runoff Coefficient, The Runoff Coefficient given W-Index formula is defined as the representation of the fraction of rainfall that is transformed into surface runoff, indicating the efficiency of precipitation absorption and retention by the underlying surface. Runoff Coefficient is denoted by C_r symbol.
