Time of Peak given Peak Discharge Solution

STEP 0: Pre-Calculation Summary

Formula Used

Time of Peak = 2.08*Area of Catchment/Peak Discharge
T_p = 2.08*A/Q_p
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 geographical area from which water flows into a particular point, such as a well, stream, or reservoir.
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

T_p = 2.08*A/Q_p --> 2.08*3/0.891

Evaluating ... ...

T_p = 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 00.004 seconds)

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

Time of Peak given Peak Discharge Formula

LaTeX Go

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

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.
