Flood Discharge Solution

STEP 0: Pre-Calculation Summary

Formula Used

Flood Discharge = Flood Coefficient*(Catchment Area for Flood Discharge)^(Flood Index)
Q_fe = C_F*(A_fd)^(n)
This formula uses 4 Variables

Variables Used

Flood Discharge - (Measured in Cubic Meter per Second) - Flood discharge refers to the volume of water flowing through a river or stream during a flood event, typically measured in m³/s or cfs.
Flood Coefficient - Flood Coefficient refers to a constant value which depend upon catchment and flood characteristic.
Catchment Area for Flood Discharge - (Measured in Square Meter) - Catchment Area for Flood Discharge refers to an area of land where all water flows to a single stream, river, lake or even ocean.
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.

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: 3.1 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

Q_fe = C_F*(A_fd)^(n) --> 0.12625*(2)^(3.1)

Evaluating ... ...

Q_fe = 1.08249119716166

STEP 3: Convert Result to Output's Unit

1.08249119716166 Cubic Meter per Second --> No Conversion Required

FINAL ANSWER

1.08249119716166 ≈ 1.082491 Cubic Meter per Second <-- Flood Discharge

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 Flood Discharge = Flood Coefficient*(Catchment Area for Flood Discharge)^(Flood Index) to calculate 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 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_fd) & Flood Index (n) and hit the calculate button. Here is how the Flood Discharge calculation can be explained with given input values -> 1.082491 = 0.12625*(2)^(3.1).
