W-Index given Runoff Coefficient Solution

STEP 0: Pre-Calculation Summary

Formula Used

W-Index = Intensity of Rainfall*(1-Runoff Coefficient)
W = I*(1-C_r)
This formula uses 3 Variables

Variables Used

W-Index - W-Index is the average infiltration rate during the time when the rainfall intensity exceeds the infiltration rate.
Intensity of Rainfall - (Measured in Millimeter per Minute) - Intensity of Rainfall is defined as the ratio of the total amount of rain (rainfall depth) falling during a given period to the duration of the period.
Runoff Coefficient - Runoff Coefficient is a dimensionless coefficient relating the amount of runoff to the amount of precipitation received.

STEP 1: Convert Input(s) to Base Unit

Intensity of Rainfall: 16 Millimeter per Minute --> 16 Millimeter per Minute No Conversion Required
Runoff Coefficient: 0.5 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

W = I*(1-C_r) --> 16*(1-0.5)

Evaluating ... ...

W = 8

STEP 3: Convert Result to Output's Unit

8 --> No Conversion Required

FINAL ANSWER

8 <-- W-Index

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)

W-Index given Runoff Coefficient Formula

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

What is w Index ?

The "W index is actually the average rate of infiltration and it is when the intensity of the rainfall increase and go beyond the rate of infiltration .
