Flood Discharge Solution

Follow our step by step solution on how to calculate Flood Discharge?

FIRST Step Consider the formula

Q fe = C F \cdot {(A fd)}^{n}

Next Step Substitute values of Variables

∴

Q fe = 0.1262 \cdot {(2m²)}^{3.1}

Next Step Prepare to Evaluate

∴

Q fe = 0.1262 \cdot {(2)}^{3.1}

Next Step Evaluate

∴

Q fe = 1.08249119716166m³/s

LAST Step Rounding Answer

∴

Q fe = 1.0825m³/s

Formulas to find Flood Discharge

Flood Coefficient

Flood Coefficient refers to a constant value which depend upon catchment and flood characteristic.

Symbol: C_F

Measurement: NAUnit: Unitless

Note: Value should be greater than 0.

Formulas to find Flood Coefficient

Catchment Area for Flood Discharge

Catchment Area for Flood Discharge refers to an area of land where all water flows to a single stream, river, lake or even ocean.

Symbol: A_fd

Measurement: AreaUnit: m²

Note: Value can be positive or negative.

Formulas to find Catchment Area for Flood Discharge

Flood Index

The flood Index refers to the severity of a flood event, considering factors like water level, flow rate, and impacted area, for comparative analysis.

Symbol: n

Measurement: NAUnit: Unitless

Note: Value should be greater than 0.

Formulas to find Flood Index

Other formulas in Flood Discharge Method category

Go Catchment Area given Flood Discharge

A fd = {(\frac{Q fe}{C F})}^{\frac{1}{n}}

Go Flood Coefficient given Flood Discharge

C F = (\frac{Q fe}{{(A fd)}^{n}})

Go Flood Frequency given Recurrence Interval

F = \frac{100}{T r}

How to Evaluate Flood Discharge?

Flood Discharge evaluator uses Flood Discharge = Flood Coefficient*(Catchment Area for Flood Discharge)^(Flood Index) to evaluate the 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. Flood Discharge is denoted by Q_fe symbol.

How to evaluate Flood Discharge using this online evaluator? To use this online evaluator for Flood Discharge, enter Flood Coefficient (C_F), Catchment Area for Flood Discharge (A_fd) & Flood Index (n) and hit the calculate button.

FAQs on Flood Discharge

What is the formula to find Flood Discharge?

The formula of Flood Discharge is expressed as Flood Discharge = Flood Coefficient*(Catchment Area for Flood Discharge)^(Flood Index). Here is an example- 1.082491 = 0.12625*(2)^(3.1).

How to calculate Flood Discharge?

With Flood Coefficient (C_F), Catchment Area for Flood Discharge (A_fd) & Flood Index (n) we can find Flood Discharge using the formula - Flood Discharge = Flood Coefficient*(Catchment Area for Flood Discharge)^(Flood Index).

Can the Flood Discharge be negative?

Yes, the Flood Discharge, measured in Volumetric Flow Rate can be negative.

Which unit is used to measure Flood Discharge?

Flood Discharge is usually measured using the Cubic Meter per Second[m³/s] for Volumetric Flow Rate. Cubic Meter per Day[m³/s], Cubic Meter per Hour[m³/s], Cubic Meter per Minute[m³/s] are the few other units in which Flood Discharge can be measured.
