Lag Time given Time of Peak Solution

STEP 0: Pre-Calculation Summary

Formula Used

Basin Lag = Time of Peak-Standard Duration of Effective Rainfall/2
t_p = T_p-t_r/2
This formula uses 3 Variables

Variables Used

Basin Lag - (Measured in Second) - Basin Lag is the elapsed time between the occurrences of the centroids of the effective rainfall.
Time of Peak - (Measured in Second) - Time of Peak is the time interval from the start of rainfall to the peak discharge.
Standard Duration of Effective Rainfall - (Measured in Second) - Standard Duration of Effective Rainfall as adopted by Snyder.

STEP 1: Convert Input(s) to Base Unit

Time of Peak: 7 Hour --> 25200 Second (Check conversion here)
Standard Duration of Effective Rainfall: 2 Hour --> 7200 Second (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

t_p = T_p-t_r/2 --> 25200-7200/2

Evaluating ... ...

t_p = 21600

STEP 3: Convert Result to Output's Unit

21600 Second -->6 Hour (Check conversion here)

FINAL ANSWER

6 Hour <-- Basin Lag

(Calculation completed in 00.020 seconds)

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 Lag Time given Time of Peak?

Lag Time given Time of Peak calculator uses Basin Lag = Time of Peak-Standard Duration of Effective Rainfall/2 to calculate the Basin Lag, The Lag Time given Time of Peak formula is defined as the elapsed time between the occurrences of the centroids of the effective rainfall. Basin Lag is denoted by t_p symbol.

How to calculate Lag Time given Time of Peak using this online calculator? To use this online calculator for Lag Time given Time of Peak, enter Time of Peak (T_p) & Standard Duration of Effective Rainfall (t_r) and hit the calculate button. Here is how the Lag Time given Time of Peak calculation can be explained with given input values -> 0.001793 = 25200-7200/2.

FAQ

What is Lag Time given Time of Peak?
