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 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

Base Length in SCS Triangular Unit Hydrograph Formula

LaTeX Go

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.
