Catchment Area given Peak Discharge Solution

STEP 0: Pre-Calculation Summary
Formula Used
Area of Catchment = Time of Peak*Peak Discharge/2.08
A = Tp*Qp/2.08
This formula uses 3 Variables
Variables Used
Area of Catchment - (Measured in Square Kilometer) - Area of catchment is the area from which rain flows into a particular river or lake.
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 = Tp*Qp/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
(Calculation completed in 00.020 seconds)

Time of Concentration given Time of Peak
Go Time of Concentration = (Time of Peak-(Standard Duration of Effective Rainfall/2))/0.6
Duration of Effective Rainfall for given Time of Peak
Go Standard Duration of Effective Rainfall = 2*(Time of Peak-0.6*Time of Concentration)
Time of Peak given Time of Concentration
Go Time of Peak = 0.6*Time of Concentration+Standard Duration of Effective Rainfall/2
Duration of Effective Rainfall given Time of Peak
Go Standard Duration of Effective Rainfall = 2*(Time of Peak-Basin Lag)
Time of Peak or Time of Rise
Go Time of Peak = (Standard Duration of Effective Rainfall/2)+Basin Lag
Lag Time given Time of Peak
Go Basin Lag = Time of Peak-Standard Duration of Effective Rainfall/2
Catchment Area given Peak Discharge
Go Area of Catchment = Time of Peak*Peak Discharge/2.08
Time of Peak given Peak Discharge
Go Time of Peak = 2.08*Area of Catchment/Peak Discharge
Peak Discharge
Go Peak Discharge = 2.08*Area of Catchment/Time of Peak
Time of Recession as Suggested in SCS
Go Time of Recession = 1.67*Time of Peak
Time of Peak given Time of Recession
Go Time of Peak = Time of Recession/1.67
Base Length in SCS Triangular Unit Hydrograph
Go Base Length = 2.67*Time of Peak
Time of Peak given Base Length
Go Time of Peak = Base Length/2.67

Catchment Area given Peak Discharge Formula

Area of Catchment = Time of Peak*Peak Discharge/2.08
A = Tp*Qp/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.
