Snyder's Equation for Time Base Solution

STEP 0: Pre-Calculation Summary

Formula Used

Time Base = (72+3*Modified Basin Lag)
t_b = (72+3*t'_p)
This formula uses 2 Variables

Variables Used

Time Base - (Measured in Hour) - Time Base is the time from which the direct runoff begins until the direct-runoff.
Modified Basin Lag - (Measured in Hour) - Modified Basin Lag for an effective duration rainfall.

STEP 1: Convert Input(s) to Base Unit

Modified Basin Lag: 6.22 Hour --> 6.22 Hour No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

t_b = (72+3*t'_p) --> (72+3*6.22)

Evaluating ... ...

t_b = 90.66

What is Basin Lag?

Basin lag time, defined as the elapsed time between the occurrences of the centroids of the effective rainfall and 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 difference between Synthetic Unit Hydrograph & Unit Hydrograph?

A Synthetic Unit Hydrograph retains all the features of the unit hydrograph but does not require rainfall-runoff data. A synthetic unit hydrograph is derived from theory and experience, and its purpose is to simulate basin diffusion by estimating the basin lag based on a certain formula or procedure.
A Unit Hydrograph shows the temporal change in flow, or discharge, per unit of runoff. In other words, how the flow of a stream will be affected over time by the addition of one unit of runoff. The unit hydrograph is a useful tool in the process of predicting the impact of precipitation on streamflow.
