Catchment Area given Flood Discharge Solution

STEP 0: Pre-Calculation Summary

Formula Used

Catchment Area for Flood Discharge = (Flood Discharge/(Flood Coefficient))^(1/Flood Index)
A_fd = (Q_fe/(C_F))^(1/n)
This formula uses 4 Variables

Variables Used

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 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.
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 Discharge: 1.08 Cubic Meter per Second --> 1.08 Cubic Meter per Second No Conversion Required
Flood Coefficient: 0.12625 --> No Conversion Required
Flood Index: 3.1 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

A_fd = (Q_fe/(C_F))^(1/n) --> (1.08/(0.12625))^(1/3.1)

Evaluating ... ...

A_fd = 1.99851409562374

STEP 3: Convert Result to Output's Unit

1.99851409562374 Square Meter --> No Conversion Required

FINAL ANSWER

1.99851409562374 ≈ 1.998514 Square Meter <-- Catchment Area for Flood Discharge

What is Catchment Area ?

A catchment is an area of land where water collects when it rains, often bounded by hills. As the water flows over the landscape it finds its way into streams and down into the soil, eventually feeding the river.

How to Calculate Catchment Area given Flood Discharge?

Catchment Area given Flood Discharge calculator uses Catchment Area for Flood Discharge = (Flood Discharge/(Flood Coefficient))^(1/Flood Index) to calculate the Catchment Area for Flood Discharge, The Catchment Area given Flood Discharge is defined as the value of area of basin when we have prior information of other parameters used. Catchment Area for Flood Discharge is denoted by A_fd symbol.

How to calculate Catchment Area given Flood Discharge using this online calculator? To use this online calculator for Catchment Area given Flood Discharge, enter Flood Discharge (Q_fe), Flood Coefficient (C_F) & Flood Index (n) and hit the calculate button. Here is how the Catchment Area given Flood Discharge calculation can be explained with given input values -> 1.955777 = (1.08/(0.12625))^(1/3.1).
