Time of Recession as Suggested in SCS Solution

STEP 0: Pre-Calculation Summary

Formula Used

Time of Recession = 1.67*Time of Peak
Tc = 1.67*T_p
This formula uses 2 Variables

Variables Used

Time of Recession - (Measured in Second) - Time of Recession represents the withdrawal of water from the storage built up in the basin during the earlier phases of the hydrograph.
Time of Peak - (Measured in Second) - Time of Peak is the time interval from the start of rainfall to the peak discharge.

STEP 1: Convert Input(s) to Base Unit

Time of Peak: 7 Hour --> 25200 Second (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

Tc = 1.67*T_p --> 1.67*25200

Evaluating ... ...

Tc = 42084

STEP 3: Convert Result to Output's Unit

42084 Second -->11.69 Hour (Check conversion here)

FINAL ANSWER

11.69 Hour <-- Time of Recession

(Calculation completed in 00.004 seconds)

Time of Concentration given Time of Peak

Go Time of Concentration = (Time of Peak-(Standard Duration of Effective Rainfall/2))/0.6

Duration of Effective Rainfall for given Time of Peak

Go Standard Duration of Effective Rainfall = 2*(Time of Peak-0.6*Time of Concentration)

Time of Peak given Time of Concentration

Go Time of Peak = 0.6*Time of Concentration+Standard Duration of Effective Rainfall/2

Duration of Effective Rainfall given Time of Peak

Go Standard Duration of Effective Rainfall = 2*(Time of Peak-Basin Lag)

Time of Peak or Time of Rise

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

Lag Time given Time of Peak

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

Catchment Area given Peak Discharge

Go Area of Catchment = Time of Peak*Peak Discharge/2.08

Time of Peak given Peak Discharge

Go Time of Peak = 2.08*Area of Catchment/Peak Discharge

Peak Discharge

Go Peak Discharge = 2.08*Area of Catchment/Time of Peak

Time of Recession as Suggested in SCS

Go Time of Recession = 1.67*Time of Peak

Time of Peak given Time of Recession

Go Time of Peak = Time of Recession/1.67

Base Length in SCS Triangular Unit Hydrograph

Go Base Length = 2.67*Time of Peak

Time of Peak given Base Length

Go Time of Peak = Base Length/2.67

Time of Recession as Suggested in SCS Formula

Time of Recession = 1.67*Time of Peak
Tc = 1.67*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 SCS Unit Hydrograph?

The Soil Conservation Service (SCS) proposed a parametric UH model; this model is included in the program. The model is based upon averages of UH derived from gaged rainfall and runoff for a large number of small agricultural watersheds throughout the US.

How to Calculate Time of Recession as Suggested in SCS?
