Time of Peak given Peak Discharge Solution

STEP 0: Pre-Calculation Summary
Formula Used
Time of Peak = 2.08*Area of Catchment/Peak Discharge
Tp = 2.08*A/Qp
This formula uses 3 Variables
Variables Used
Time of Peak - (Measured in Second) - Time of Peak is the time interval from the start of rainfall to the peak discharge.
Area of Catchment - (Measured in Square Kilometer) - Area of catchment is the area from which rain flows into a particular river or lake.
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
Area of Catchment: 3 Square Kilometer --> 3 Square Kilometer 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
Tp = 2.08*A/Qp --> 2.08*3/0.891
Evaluating ... ...
Tp = 7.003367003367
STEP 3: Convert Result to Output's Unit
7.003367003367 Second -->0.0019453797231575 Hour (Check conversion here)
FINAL ANSWER
0.0019453797231575 0.001945 Hour <-- Time of Peak
(Calculation completed in 00.008 seconds)

13 SCS Triangular Unit Hydrograph Calculators

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

Time of Peak given Peak Discharge Formula

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

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.
