Note: Value should be greater than 0.

Formulas to find Base Length

Time of Peak

Time of Peak is the time interval from the start of rainfall to the peak discharge.

Symbol: T_p

Measurement: TimeUnit: h

Note: Value should be greater than 0.

Formulas to find Time of Peak

Other formulas in SCS Triangular Unit Hydrograph category

Go Time of Peak or Time of Rise

T p = (\frac{t r}{2}) + t p

Go Lag Time given Time of Peak

t p = T p - \frac{t r}{2}

Go Time of Recession as Suggested in SCS

Tc = 1.67 \cdot T p

Go Time of Peak given Time of Recession

T p = \frac{Tc}{1.67}
