Runoff given W-Index Solution

STEP 0: Pre-Calculation Summary

Formula Used

Runoff Volume = Precipitation-(W-Index*Duration of the Rainfall)
Q_V = P-(W*D)
This formula uses 4 Variables

Variables Used

Runoff Volume - (Measured in Cubic Meter) - Runoff Volume is the average amount of water that flows down a particular river, per year, expressed as a volume of water flowing past a given point.
Precipitation - (Measured in Millimeter) - Precipitation is the primary water input to the hydrologic cycle and is evaluated for all water budget calculations.
W-Index - W-Index is the average infiltration rate during the time when the rainfall intensity exceeds the infiltration rate.
Duration of the Rainfall - (Measured in Second) - Duration of the Rainfall corresponding to rainfall depth is the total time during which the precipitation occurs.

STEP 1: Convert Input(s) to Base Unit

Precipitation: 120 Millimeter --> 120 Millimeter No Conversion Required
W-Index: 2.01 --> No Conversion Required
Duration of the Rainfall: 50 Second --> 50 Second No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

Q_V = P-(W*D) --> 120-(2.01*50)

Evaluating ... ...

Q_V = 19.5

STEP 3: Convert Result to Output's Unit

19.5 Cubic Meter --> No Conversion Required

FINAL ANSWER

19.5 Cubic Meter <-- Runoff Volume

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 given W-Index Formula

Runoff Volume = Precipitation-(W-Index*Duration of the Rainfall)
Q_V = P-(W*D)

What is Runoff ?

Runoff occurs when there is more water than land can absorb. The excess liquid flows across the surface of the land and into nearby creeks, streams, or ponds. Runoff can come from both natural processes and human activity. The most familiar type of natural runoff is snowmelt.

How to Calculate Runoff given W-Index?

Runoff given W-Index calculator uses Runoff Volume = Precipitation-(W-Index*Duration of the Rainfall) to calculate the Runoff Volume, The Runoff given W-Index is defined as excess liquid flows across surface of land and into nearby creeks, streams, or ponds. Runoff Volume is denoted by Q_V symbol.

How to calculate Runoff given W-Index using this online calculator? To use this online calculator for Runoff given W-Index, enter Precipitation (P), W-Index (W) & Duration of the Rainfall (D) and hit the calculate button. Here is how the Runoff given W-Index calculation can be explained with given input values -> 19.5 = 0.12-(2.01*50).

FAQ

What is Runoff given W-Index?

The Runoff given W-Index is defined as excess liquid flows across surface of land and into nearby creeks, streams, or ponds and is represented as Q_V = P-(W*D) or Runoff Volume = Precipitation-(W-Index*Duration of the Rainfall). Precipitation is the primary water input to the hydrologic cycle and is evaluated for all water budget calculations, W-Index is the average infiltration rate during the time when the rainfall intensity exceeds the infiltration rate & Duration of the Rainfall corresponding to rainfall depth is the total time during which the precipitation occurs.

How to calculate Runoff given W-Index?

The Runoff given W-Index is defined as excess liquid flows across surface of land and into nearby creeks, streams, or ponds is calculated using Runoff Volume = Precipitation-(W-Index*Duration of the Rainfall).
