Basin Lag given Modified Basin Lag Solution

STEP 0: Pre-Calculation Summary

Formula Used

Basin Lag = (Modified Basin Lag-(Non-standard rainfall duration/4))/(21/22)
t_p = (t'_p-(t_R/4))/(21/22)
This formula uses 3 Variables

Variables Used

Basin Lag - (Measured in Hour) - Basin Lag is the elapsed time between the occurrences of the centroids of the effective rainfall.
Modified Basin Lag - (Measured in Hour) - Modified Basin Lag for an effective duration rainfall.
Non-standard rainfall duration - (Measured in Hour) - Non-standard rainfall duration to derive modified basin lag.

STEP 1: Convert Input(s) to Base Unit

Modified Basin Lag: 6.22 Hour --> 6.22 Hour No Conversion Required
Non-standard rainfall duration: 2 Hour --> 2 Hour No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

t_p = (t'_p-(t_R/4))/(21/22) --> (6.22-(2/4))/(21/22)

Evaluating ... ...

t_p = 5.99238095238095

STEP 3: Convert Result to Output's Unit

21572.5714285714 Second -->5.99238095238095 Hour (Check conversion here)

FINAL ANSWER

5.99238095238095 ≈ 5.992381 Hour <-- Basin Lag

What is Lag Time in hydrology?

The lag time is the delay between the maximum rainfall amount and the peak discharge. The shape of a hydrograph varies in each river basin and each storm event. This increases lag time. The peak discharge is also lower as it takes water longer to reach the river channel.
