Variables

Drainage Area

Drainage Area is the land region from which all precipitation flows to a common outlet, such as a river, lake, or ocean.

Symbol: A

Measurement: AreaUnit: m²

Note: Value should be greater than 0.

Formulas to find Drainage Area

Peak Rate of Runoff

Peak Rate of Runoff is the maximum rate of discharge during the period of runoff caused by a storm.

Symbol: q_p

Measurement: Volumetric Flow RateUnit: m³/s

Note: Value should be greater than 0.

Formulas to find Peak Rate of Runoff

Runoff Coefficient

Runoff Coefficient is a dimensionless coefficient relating the amount of runoff to the amount of precipitation received.

Symbol: C_r

Measurement: NAUnit: Unitless

Note: Value should be greater than 0.

Formulas to find Runoff Coefficient

Average Rainfall Rate

Average Rainfall Rate is a measure of the intensity of rainfall by calculating the amount of rain that would fall over a given interval of time.

Symbol: I

Measurement: SpeedUnit: m/s

Note: Value should be greater than 0.

How to Evaluate Drainage Area given Stormwater?

Drainage Area given Stormwater evaluator uses Drainage Area = Peak Rate of Runoff/(Runoff Coefficient*Average Rainfall Rate) to evaluate the Drainage Area, The Drainage Area given Stormwater formula is defined as 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. Drainage Area is denoted by A symbol.

How to evaluate Drainage Area given Stormwater using this online evaluator? To use this online evaluator for Drainage Area given Stormwater, enter Peak Rate of Runoff (q_p), Runoff Coefficient (C_r) & Average Rainfall Rate (I) and hit the calculate button.

FAQs on Drainage Area given Stormwater

What is the formula to find Drainage Area given Stormwater?

The formula of Drainage Area given Stormwater is expressed as Drainage Area = Peak Rate of Runoff/(Runoff Coefficient*Average Rainfall Rate). Here is an example- 50.24 = 1.256/(0.5*0.05).

How to calculate Drainage Area given Stormwater?

With Peak Rate of Runoff (q_p), Runoff Coefficient (C_r) & Average Rainfall Rate (I) we can find Drainage Area given Stormwater using the formula - Drainage Area = Peak Rate of Runoff/(Runoff Coefficient*Average Rainfall Rate).

Can the Drainage Area given Stormwater be negative?

No, the Drainage Area given Stormwater, measured in Area cannot be negative.

Which unit is used to measure Drainage Area given Stormwater?
