Drainage Area when Peak Discharge for Field Application is Considered 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

What is Surface Runoff & Drainage Area?

Surface runoff is water, from rain, snowmelt, or other sources, that flows over the land surface, and is a major component of the water cycle. Runoff that occurs on surfaces before reaching a channel is also called overland flow. A land area which produces runoff draining to a common point is called a watershed.
A Drainage area is the total surface area, upstream of a point on a stream, where the water from rain, snowmelt, or irrigation which is not absorbed into the ground flows over the ground surface, back into streams, to finally reach that point.

What is Peak Discharge & explain use of Runoff Coefficient?

The maximum rate of discharge during the period of runoff caused by a storm is called a peak flow. The information about peak flows and associated volume of runoff during various floods that have been observed in the past can be compiled by the analysis of the observed discharge data and runoff hydrographs.
Runoff coefficient is a dimensionless factor that is used to convert the rainfall amounts to runoff. It represents the integrated effect of catchment losses and hence depends upon the nature of the land surface, slope, degree of saturation, and rainfall intensity. It is a larger value for areas with low infiltration and high runoff (pavement, steep gradient), and lower for permeable, well-vegetated areas (forest, flat land).
