Barlow's Formula for Runoff Solution

STEP 0: Pre-Calculation Summary

Formula Used

Runoff = Barlow's Runoff Coefficient*Rainfall
R = K_b*P
This formula uses 3 Variables

Variables Used

Runoff - (Measured in Centimeter) - Runoff is usually measured is either seasonal measured or annual measured.
Barlow's Runoff Coefficient - Barlow's Runoff Coefficient for different catchment characteristics and seasons.
Rainfall - (Measured in Centimeter) - Rainfall is measured here is the annual rainfall in a particular year.

STEP 1: Convert Input(s) to Base Unit

Barlow's Runoff Coefficient: 0.15 --> No Conversion Required
Rainfall: 75 Centimeter --> 75 Centimeter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

R = K_b*P --> 0.15*75

Evaluating ... ...

R = 11.25

STEP 3: Convert Result to Output's Unit

0.1125 Meter -->11.25 Centimeter (Check conversion here)

FINAL ANSWER

11.25 Centimeter <-- Runoff

(Calculation completed in 00.004 seconds)

What is Direct Runoff?

Direct Surface Runoff is the rain or meltwater that runs off during the rain or melt event as overland flow or in the vegetation cover above a frozen soil. The meltwater and the rain falling onto snow or on frozen ground reach a stream along different pathways.

What is Precipitation?

Precipitation is any liquid or frozen water that forms in the atmosphere and falls back to the Earth. It comes in many forms, like rain, sleet, and snow. Along with evaporation and condensation, precipitation is one of the three major parts of the global water cycle.

How to Calculate Barlow's Formula for Runoff?

Barlow's Formula for Runoff calculator uses Runoff = Barlow's Runoff Coefficient*Rainfall to calculate the Runoff, The Barlow's Formula for Runoff formula is defined as it is developed by Barlow, the first Chief Engineer of the Hydro-electric Survey of India based on his study in small catchments in Uttar Pradesh. Runoff is denoted by R symbol.
