Variables Used

Flood Discharge by Fuller's Formula - (Measured in Cubic Meter per Second) - Flood Discharge by Fuller's Formula refers to peak discharge based on catchment area and rainfall intensity, considering regional characteristics.
Fuller's Constant - Fuller's Constant refers to an empirical coefficient used in Fuller's formula to estimate peak flood discharge, adjusted for regional hydrological conditions.
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, typically in km unit.
Time Period for a Flood Discharge - (Measured in Second) - Time Period for a Flood Discharge refers to number of years after which a flood is recorded.

STEP 1: Convert Input(s) to Base Unit

Fuller's Constant: 0.185 --> No Conversion Required
Catchment Area for Flood Discharge: 2.4 Square Kilometer --> 2400000 Square Meter (Check conversion here)
Time Period for a Flood Discharge: 2.2 Year --> 69425294.4 Second (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

Q_FL = C_FL*((A_km)^(0.8))*(1+0.8*log(T_m,e))*(1+2.67*(A_km)^(-0.3)) --> 0.185*((2400000)^(0.8))*(1+0.8*log(69425294.4,e))*(1+2.67*(2400000)^(-0.3))

Evaluating ... ...

Q_FL = 25355.771503865

STEP 3: Convert Result to Output's Unit

25355.771503865 Cubic Meter per Second --> No Conversion Required

FINAL ANSWER

25355.771503865 ≈ 25355.77 Cubic Meter per Second <-- Flood Discharge by Fuller's Formula
