Runoff Coefficient given W-Index Solution

STEP 0: Pre-Calculation Summary

Formula Used

Runoff Coefficient = Rainfall Depth-(W-Index*Rainfall Duration)
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 - (Measured in Meter) - Rainfall Depth refers to the vertical height of rainwater accumulated over a surface during a specific period, typically measured in millimeters (mm) or inches.
W-Index - (Measured in Meter per Second) - W-Index refers to the uniform rate of infiltration during a rainstorm after initial infiltration capacity has decreased, typically measured in cm/h.
Rainfall Duration - (Measured in Second) - Rainfall duration refers to the length of time over which a rainfall event occurs, typically measured in hours or minutes, affecting runoff and infiltration.

STEP 1: Convert Input(s) to Base Unit

Rainfall Depth: 12 Centimeter --> 0.12 Meter (Check conversion here)
W-Index: 1.714 Centimeter per Hour --> 4.76111111111111E-06 Meter per Second (Check conversion here)
Rainfall Duration: 3.5 Hour --> 12600 Second (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

C_r = P_cm-(W*t_r) --> 0.12-(4.76111111111111E-06*12600)

Evaluating ... ...

C_r = 0.06001

STEP 3: Convert Result to Output's Unit

0.06001 --> No Conversion Required

FINAL ANSWER

0.06001 <-- Runoff Coefficient

Runoff Coefficient given W-Index

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

W-Index given Duration of Rainfall

Go W-Index = (Rainfall Depth-Runoff Depth)/Rainfall Duration

Duration of Rainfall given W-Index

Go Rainfall Duration = (Rainfall Depth-Runoff Depth)/W-Index

Precipitation given W-Index

Go Rainfall Depth = (W-Index*Rainfall Duration)+Runoff Depth

Runoff given W-Index

Go Runoff Depth = Rainfall Depth-(W-Index*Rainfall Duration)

W-Index given Runoff Coefficient

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

Runoff Coefficient given W-Index Formula

Runoff Coefficient = Rainfall Depth-(W-Index*Rainfall Duration)
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-(W-Index*Rainfall Duration) 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.
