Duration of Effective Rainfall for given Time of Peak Solution

STEP 0: Pre-Calculation Summary
Formula Used
Standard Duration of Effective Rainfall = 2*(Time of Peak-0.6*Time of Concentration)
tr = 2*(Tp-0.6*tc)
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.
Time of Concentration - (Measured in Hour) - Time of Concentration is a concept used in hydrology to measure the response of a watershed to a rain event.
STEP 1: Convert Input(s) to Base Unit
Time of Peak: 7 Hour --> 7 Hour No Conversion Required
Time of Concentration: 10 Hour --> 10 Hour No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
tr = 2*(Tp-0.6*tc) --> 2*(7-0.6*10)
Evaluating ... ...
tr = 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)

SCS Triangular Unit Hydrograph Calculators

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 for given Time of Peak Formula

​LaTeX ​Go
Standard Duration of Effective Rainfall = 2*(Time of Peak-0.6*Time of Concentration)
tr = 2*(Tp-0.6*tc)

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.
