Basin Lag given Modified Basin Lag for Effective Duration Solution

STEP 0: Pre-Calculation Summary

Formula Used

Basin Lag = (4*Modified Basin Lag+Standard Duration of Effective Rainfall-Non-standard rainfall duration)/4
t_p = (4*t'_p+t_r-t_R)/4
This formula uses 4 Variables

Variables Used

Basin Lag - (Measured in Second) - Basin Lag is the elapsed time between the occurrences of the centroids of the effective rainfall.
Modified Basin Lag - (Measured in Second) - Modified Basin Lag for an effective duration rainfall.
Standard Duration of Effective Rainfall - (Measured in Second) - Standard Duration of Effective Rainfall as adopted by Snyder.
Non-standard rainfall duration - (Measured in Second) - Non-standard rainfall duration to derive modified basin lag.

STEP 1: Convert Input(s) to Base Unit

Modified Basin Lag: 6.22 Hour --> 22392 Second (Check conversion here)
Standard Duration of Effective Rainfall: 2 Hour --> 7200 Second (Check conversion here)
Non-standard rainfall duration: 2 Hour --> 7200 Second (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

t_p = (4*t'_p+t_r-t_R)/4 --> (4*22392+7200-7200)/4

Evaluating ... ...

t_p = 22392

STEP 3: Convert Result to Output's Unit

22392 Second -->6.22 Hour (Check conversion here)

FINAL ANSWER

6.22 Hour <-- Basin Lag

(Calculation completed in 00.004 seconds)

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.
