online_dynamic_hydraulic_diffusivity:   Dynamic hydraulic diffusivity in unsteady open-channel flow
INPUT DATA:

Select:    

Flow velocity u :    
 

Flow depth y :    
 

Bottom slope So :    
 

Exponent β :    
  [Q = α A β]

Roll waves in an open channel.
Formulas:

F = u/(gy)1/2

V = (β - 1)F

νk = (uy)/(2So)

νd = νk (1 - V2)

OUTPUT:

Froude number F :  0

Vedernikov number V :  0

Kinematic hydraulic diffusivity νk :  0

Dynamic hydraulic diffusivity νd :  0


Reference:  The dynamic hydraulic diffusivity reexamined.
