Barlow's Formula for Runoff Solution

STEP 0: Pre-Calculation Summary
Formula Used
Runoff = Barlow's Runoff Coefficient*Rainfall
R = Kb*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 = Kb*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.
