Shallow Concentrated Flow

Shallow concentrated flow travel time is computed as:
EquationObject2941
Equation 4-18.
Where:
  • t
    sc
     = shallow concentrated flow time (hr.)
  • L
    sc
     = shallow concentrated flow length (ft)
  • K
     = 16.13 for unpaved surface, 20.32 for paved surface
  • S
    sc
     = shallow concentrated flow slope (ft/ft)
