Value of Peak Discharge Solution

Follow our step by step solution on how to calculate Value of Peak Discharge?

FIRST Step Consider the formula

Q p = C r \cdot A D \cdot i

Next Step Substitute values of Variables

∴

Q p = 0.5 \cdot 18km² \cdot 1.6mm/h

Next Step Convert Units

∴

Q p = 0.5 \cdot 1.8E+7m² \cdot 4.4E-7m/s

Next Step Prepare to Evaluate

∴

Q p = 0.5 \cdot 1.8E+7 \cdot 4.4E-7

LAST Step Evaluate

∴

Q p = 4m³/s

Variables

Peak Discharge

Peak Discharge is the maximum volume flow rate passing a particular location during an event.

Symbol: Q_p

Measurement: Volumetric Flow RateUnit: m³/s

Note: Value should be greater than 0.

Formulas to find Peak Discharge

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

Drainage Area

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.

Symbol: A_D

Measurement: AreaUnit: km²

Note: Value can be positive or negative.

Formulas to find Drainage Area

Intensity of Rainfall

Intensity of Rainfall is the ratio of the total amount of rain (rainfall depth) falling during a given period to the duration of the period.

Symbol: i

Measurement: SpeedUnit: mm/h

Note: Value should be greater than 0.
