Drainage Area given Peak Discharge for Field Application Solution

STEP 0: Pre-Calculation Summary

Formula Used

Drainage Area = Peak Discharge/((1/3.6)*Mean Intensity of Precipitation*Runoff Coefficient)
A_D = Q_p/((1/3.6)*i_tcp*C_r)
This formula uses 4 Variables

Variables Used

Drainage Area - (Measured in Square Meter) - Drainage Area is the total surface area, where the water from rain which is not absorbed into the ground flows over the ground surface, back into streams, to finally reach that point.
Peak Discharge - (Measured in Cubic Meter per Second) - Peak Discharge is the maximum volume flow rate passing a particular location during an event.
Mean Intensity of Precipitation - (Measured in Meter per Second) - Mean Intensity of Precipitation (mm/hr) for a duration equal to tc and an exceedance probability P.
Runoff Coefficient - Runoff Coefficient is a dimensionless coefficient relating the amount of runoff to the amount of precipitation received.

STEP 1: Convert Input(s) to Base Unit

Peak Discharge: 4 Cubic Meter per Second --> 4 Cubic Meter per Second No Conversion Required
Mean Intensity of Precipitation: 5.76 Millimeter per Hour --> 1.6E-06 Meter per Second (Check conversion here)
Runoff Coefficient: 0.5 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

A_D = Q_p/((1/3.6)*i_tcp*C_r) --> 4/((1/3.6)*1.6E-06*0.5)

Evaluating ... ...

A_D = 18000000

STEP 3: Convert Result to Output's Unit

18000000 Square Meter -->18 Square Kilometer (Check conversion here)

FINAL ANSWER

18 Square Kilometer <-- Drainage Area

(Calculation completed in 00.020 seconds)
