Duration of Effective Rainfall given Time of Peak Solution

STEP 0: Pre-Calculation Summary

Formula Used

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

Variables Used

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

STEP 1: Convert Input(s) to Base Unit

Time of Peak: 7 Hour --> 7 Hour No Conversion Required
Basin Lag: 6 Hour --> 6 Hour No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

t_r = 2*(T_p-t_p) --> 2*(7-6)

Evaluating ... ...

t_r = 2

STEP 3: Convert Result to Output's Unit

7200 Second -->2 Hour (Check conversion here)

FINAL ANSWER

2 Hour <-- Standard Duration of Effective Rainfall

(Calculation completed in 00.004 seconds)

Time of Peak or Time of Rise

LaTeX Go Time of Peak = (Standard Duration of Effective Rainfall/2)+Basin Lag

Lag Time given Time of Peak

LaTeX Go Basin Lag = Time of Peak-Standard Duration of Effective Rainfall/2

Time of Recession as Suggested in SCS

LaTeX Go Time of Recession = 1.67*Time of Peak

Time of Peak given Time of Recession

LaTeX Go Time of Peak = Time of Recession/1.67

Duration of Effective Rainfall given Time of Peak Formula

LaTeX Go

Standard Duration of Effective Rainfall = 2*(Time of Peak-Basin Lag)
t_r = 2*(T_p-t_p)

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.
