Flood Index given Flood Discharge Solution

STEP 0: Pre-Calculation Summary
Formula Used
Flood Index = log((Discharge/Flood Coefficient),Catchment Area for Flood Discharge)
n = log((Q/CF),Aflood discharge)
This formula uses 1 Functions, 4 Variables
Functions Used
log - Logarithmic function is an inverse function to exponentiation., log(Base, Number)
Variables Used
Flood Index - Flood Index is proposed for highlighting flooded areas.
Discharge - (Measured in Cubic Meter per Second) - Discharge is the rate of flow of a liquid.
Flood Coefficient - Flood Coefficient is a constant value which depend upon catchment and flood characteristic.
Catchment Area for Flood Discharge - (Measured in Square Meter) - Catchment Area for Flood Discharge is an area of land where all water flows to a single stream, river, lake or even ocean.
STEP 1: Convert Input(s) to Base Unit
Discharge: 1.01 Cubic Meter per Second --> 1.01 Cubic Meter per Second No Conversion Required
Flood Coefficient: 0.12625 --> No Conversion Required
Catchment Area for Flood Discharge: 2 Square Meter --> 2 Square Meter No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
n = log((Q/CF),Aflood discharge) --> log((1.01/0.12625),2)
Evaluating ... ...
n = 0.333333333333333
STEP 3: Convert Result to Output's Unit
0.333333333333333 --> No Conversion Required
FINAL ANSWER
0.333333333333333 0.333333 <-- Flood Index
(Calculation completed in 00.004 seconds)

Flood Index given Flood Discharge
Go Flood Index = log((Discharge/Flood Coefficient),Catchment Area for Flood Discharge)
Flood Coefficient given Flood Discharge
Go Flood Coefficient = (Discharge/(Catchment Area for Flood Discharge)^(Flood Index))
Catchment Area given Flood Discharge
Go Catchment Area for Flood Discharge = Discharge/(Flood Coefficient)^(1/Flood Index)
Flood Discharge
Go Discharge = Flood Coefficient*(Catchment Area for Flood Discharge)^(Flood Index)
Catchment Area given Average Value of Constant
Go Catchment Area for Flood Discharge = (Discharge/2.54)^(6/5)
Flood Frequency given Recurrence Interval
Go Flood Frequency = 100/Recurrence Interval

Flood Index given Flood Discharge Formula

Flood Index = log((Discharge/Flood Coefficient),Catchment Area for Flood Discharge)
n = log((Q/CF),Aflood discharge)

What is flood ?

A flood is an overflow of water on normally dry ground. This is most commonly due to an overflowing river, a dam break, snowmelt, or heavy rainfall.
