Base Length in SCS Triangular Unit Hydrograph Solution

STEP 0: Pre-Calculation Summary

Formula Used

Base Length = 2.67*Time of Peak
T_b = 2.67*T_p
This formula uses 2 Variables

Variables Used

Base Length - (Measured in Meter) - Base Length in SCS Triangular Unit Hydrograph is a popular method used in watershed development activities, especially in small watersheds.
Time of Peak - (Measured in Hour) - 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 --> 7 Hour No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

T_b = 2.67*T_p --> 2.67*7

Evaluating ... ...

T_b = 18.69

STEP 3: Convert Result to Output's Unit

18.69 Meter --> No Conversion Required

FINAL ANSWER

18.69 Meter <-- Base Length

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

Base Length in SCS Triangular Unit Hydrograph Formula

Base Length = 2.67*Time of Peak
T_b = 2.67*T_p

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.
