Basin Lag given Standard Duration of Effective Rainfall Solution

STEP 0: Pre-Calculation Summary

Formula Used

Basin Lag = 5.5*Standard Duration of Effective Rainfall
t_p = 5.5*t_r
This formula uses 2 Variables

Variables Used

Basin Lag - (Measured in Second) - Basin Lag is the elapsed time between the occurrences of the centroids of the effective rainfall.
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

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

STEP 2: Evaluate Formula

Substituting Input Values in Formula

t_p = 5.5*t_r --> 5.5*7200

Evaluating ... ...

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.
