## Base Length in SCS Triangular Unit Hydrograph Solution

STEP 0: Pre-Calculation Summary
Formula Used
base_length = 2.67*Time of Peak
Tb = 2.67*Tp
This formula uses 1 Variables
Variables Used
Time of Peak - Time of Peak is the time interval from the start of rainfall to the peak discharge. (Measured in Hour)
STEP 1: Convert Input(s) to Base Unit
Time of Peak: 10 Hour --> 36000 Second (Check conversion here)
STEP 2: Evaluate Formula
Substituting Input Values in Formula
Tb = 2.67*Tp --> 2.67*36000
Evaluating ... ...
Tb = 96120
STEP 3: Convert Result to Output's Unit
96120 Meter -->96120000 Millimeter (Check conversion here)
96120000 Millimeter <-- Base Length
(Calculation completed in 00.016 seconds)
