Peak Discharge of D-h Unit Hydrograph Solution

STEP 0: Pre-Calculation Summary

Formula Used

Peak discharge of a D-h Unit hydrograph = 1.79*Area of Catchment^(3/4)
Q_pd = 1.79*A^(3/4)
This formula uses 2 Variables

Variables Used

Peak discharge of a D-h Unit hydrograph - (Measured in Cubic Meter per Second) - Peak discharge of a D-h Unit hydrograph is the maximum volume flow rate displays in a unit hydrograph.
Area of Catchment - (Measured in Square Meter) - Area of Catchment is the geographical area from which water flows into a particular point, such as a well, stream, or reservoir.

STEP 1: Convert Input(s) to Base Unit

Area of Catchment: 3 Square Kilometer --> 3000000 Square Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

Q_pd = 1.79*A^(3/4) --> 1.79*3000000^(3/4)

Evaluating ... ...

Q_pd = 129030.972939036

STEP 3: Convert Result to Output's Unit

129030.972939036 Cubic Meter per Second --> No Conversion Required

FINAL ANSWER

129030.972939036 ≈ 129031 Cubic Meter per Second <-- Peak discharge of a D-h Unit hydrograph

(Calculation completed in 00.022 seconds)
