Catchment Area given Peak Discharge Solution

STEP 0: Pre-Calculation Summary

Formula Used

Area of Catchment = Time of Peak*Peak Discharge/2.08
A = T_p*Q_p/2.08
This formula uses 3 Variables

Variables Used

Area of Catchment - (Measured in Square Kilometer) - Area of Catchment is the geographical area from which water flows into a particular point, such as a well, stream, or reservoir.
Time of Peak - (Measured in Hour) - Time of Peak is the time interval from the start of rainfall to the peak discharge.
Peak Discharge - (Measured in Cubic Meter per Second) - Peak Discharge is the maximum volume flow rate passing a particular location during an event.

STEP 1: Convert Input(s) to Base Unit

Time of Peak: 7 Hour --> 7 Hour No Conversion Required
Peak Discharge: 0.891 Cubic Meter per Second --> 0.891 Cubic Meter per Second No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

A = T_p*Q_p/2.08 --> 7*0.891/2.08

Evaluating ... ...

A = 2.99855769230769

STEP 3: Convert Result to Output's Unit

2998557.69230769 Square Meter -->2.99855769230769 Square Kilometer (Check conversion here)

FINAL ANSWER

2.99855769230769 ≈ 2.998558 Square Kilometer <-- Area of Catchment

Time of Peak or Time of Rise

LaTeX Go Time of Peak = (Standard Duration of Effective Rainfall/2)+Basin Lag

Lag Time given Time of Peak

LaTeX Go Basin Lag = Time of Peak-Standard Duration of Effective Rainfall/2

Time of Recession as Suggested in SCS

LaTeX Go Time of Recession = 1.67*Time of Peak

Time of Peak given Time of Recession

LaTeX Go Time of Peak = Time of Recession/1.67

Catchment Area given Peak Discharge Formula

LaTeX Go

Area of Catchment = Time of Peak*Peak Discharge/2.08
A = T_p*Q_p/2.08

What is Basin Lag?

Basin lag time, defined as the elapsed time between the occurrences of the centroids of the effective rainfall. and of the storm runoff hydrograph, is an important factor in determining the time to peak of the unit. hydrograph and the intensity of peak discharge.

What is Baseflow?

Baseflow is a portion of streamflow that is not directly generated from the excess rainfall during a storm event. In other words, this is the flow that would exist in the stream without the contribution of direct runoff from the rainfall.

How to Calculate Catchment Area given Peak Discharge?

Catchment Area given Peak Discharge calculator uses Area of Catchment = Time of Peak*Peak Discharge/2.08 to calculate the Area of Catchment, The Catchment Area given Peak Discharge formula is defined as the area of land where all of the precipitation that falls, less the water lost to evaporation and deep aquifer recharge, eventually flows to a single outlet. Area of Catchment is denoted by A symbol.

How to calculate Catchment Area given Peak Discharge using this online calculator?
