Runoff Rainfall Regression by Logarithmic Transformation Solution

STEP 0: Pre-Calculation Summary

Formula Used

Runoff = Coefficient m*exp(ln(Rainfall))+exp(ln(Coefficient β))
R = m*exp(ln(P))+exp(ln(β))
This formula uses 2 Functions, 4 Variables

Functions Used

ln - The natural logarithm, also known as the logarithm to the base e, is the inverse function of the natural exponential function., ln(Number)
exp - n an exponential function, the value of the function changes by a constant factor for every unit change in the independent variable., exp(Number)

Variables Used

Runoff - (Measured in Centimeter) - Runoff is usually measured is either seasonal measured or annual measured.
Coefficient m - Coefficient m in Logarithmic Transformation which reduces or removes the skewness of our original data.
Rainfall - (Measured in Centimeter) - Rainfall is measured here is the annual rainfall in a particular year.
Coefficient β - Coefficient β in Logarithmic Transformation reduces or removes the skewness of our original data.

STEP 1: Convert Input(s) to Base Unit

Coefficient m: 0.3 --> No Conversion Required
Rainfall: 75 Centimeter --> 75 Centimeter No Conversion Required
Coefficient β: 4 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

R = m*exp(ln(P))+exp(ln(β)) --> 0.3*exp(ln(75))+exp(ln(4))

Evaluating ... ...

R = 26.5

STEP 3: Convert Result to Output's Unit

0.265 Meter -->26.5 Centimeter (Check conversion here)

FINAL ANSWER

26.5 Centimeter <-- Runoff

What is Regression Analysis?

Regression Analysis is used to identify factors governing flood generation and routing, and to predict flow volumes and flood peaks as functions of rainfall input and antecedent wetness.

What is Runoff?

Runoff can be described as the part of the water cycle that flows over land as surface water instead of being absorbed into groundwater or evaporating. According to the U.S. Geological Survey (USGS), runoff is that part of the precipitation, snow melt, or irrigation water that appears in uncontrolled surface streams, rivers, drains, or sewers.
