Flood Discharge Solution

STEP 0: Pre-Calculation Summary

Formula Used

Discharge = Flood Coefficient*(Catchment Area for Flood Discharge)^(Flood Index)
Q = C_F*(A_{flood discharge})^(n)
This formula uses 4 Variables

Variables Used

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.
Flood Index - Flood Index is proposed for highlighting flooded areas.

STEP 1: Convert Input(s) to Base Unit

Flood Coefficient: 0.12625 --> No Conversion Required
Catchment Area for Flood Discharge: 2 Square Meter --> 2 Square Meter No Conversion Required
Flood Index: 3 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

Q = C_F*(A_{flood discharge})^(n) --> 0.12625*(2)^(3)

Evaluating ... ...

Q = 1.01

STEP 3: Convert Result to Output's Unit

1.01 Cubic Meter per Second --> No Conversion Required

FINAL ANSWER

1.01 Cubic Meter per Second <-- Discharge

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 Discharge Formula

Discharge = Flood Coefficient*(Catchment Area for Flood Discharge)^(Flood Index)
Q = C_F*(A_{flood discharge})^(n)

What is discharge ?

Discharge is the volume of water that passes through a given cross section per unit time, usually measured in cubic feet per second (cfs) or cubic meters per second (cms). Stage is the level of the water surface over a datum (often sea level).

How to Calculate Flood Discharge?

Flood Discharge calculator uses Discharge = Flood Coefficient*(Catchment Area for Flood Discharge)^(Flood Index) to calculate the Discharge, The Flood Discharge stands for the highest concentration of runoff from the basin area.The concentrated flow of the basin greatly exaggerated and over tops the natural or artificial bank and this might be called flood. Discharge is denoted by Q symbol.

How to calculate Flood Discharge using this online calculator? To use this online calculator for Flood Discharge, enter Flood Coefficient (C_F), Catchment Area for Flood Discharge (A_{flood discharge}) & Flood Index (n) and hit the calculate button. Here is how the Flood Discharge calculation can be explained with given input values -> 40 = 0.12625*(2)^(3).

FAQ

What is Flood Discharge?

The Flood Discharge stands for the highest concentration of runoff from the basin area.The concentrated flow of the basin greatly exaggerated and over tops the natural or artificial bank and this might be called flood and is represented as Q = C_F*(A_{flood discharge})^(n) or Discharge = Flood Coefficient*(Catchment Area for Flood Discharge)^(Flood Index). Flood Coefficient is a constant value which depend upon catchment and flood characteristic, Catchment Area for Flood Discharge is an area of land where all water flows to a single stream, river, lake or even ocean & Flood Index is proposed for highlighting flooded areas.

How to calculate Flood Discharge?

The Flood Discharge stands for the highest concentration of runoff from the basin area.The concentrated flow of the basin greatly exaggerated and over tops the natural or artificial bank and this might be called flood is calculated using Discharge = Flood Coefficient*(Catchment Area for Flood Discharge)^(Flood Index). To calculate Flood Discharge, you need Flood Coefficient (C_F), Catchment Area for Flood Discharge (A_{flood discharge}) & Flood Index (n). With our tool, you need to enter the respective value for Flood Coefficient, Catchment Area for Flood Discharge & Flood Index and hit the calculate button. You can also select the units (if any) for Input(s) and the Output as well.
