Channel Flow Time or Gutter Flow Time Formula Elements

Variables
Channel Flow Time
Channel Flow Time is the time taken for water to travel from the most distant point in a watershed to a specific outlet or point of interest within a channel or drainage system.
Symbol: Tm/f
Measurement: TimeUnit: min
Note: Value should be greater than 0.
Length of Drain
Length of Drain refers to the total distance from the point where water enters the drainage system to the point where it exits or discharges into a larger water body or another drainage system.
Symbol: L
Measurement: LengthUnit: km
Note: Value should be greater than 0.
Velocity in Drain
Velocity in Drain is the speed of the water flowing through the drain.
Symbol: V
Measurement: SpeedUnit: m/s
Note: Value should be greater than 0.
