   online_dynamic_hydraulic_diffusivity: Dynamic hydraulic diffusivity in unsteady open-channel flow

INPUT DATA:

Select:

Flow velocity u :

Flow depth y :

Bottom slope S_o :

Exponent β :

[Q = α A^β]

Roll waves in an open channel.
Formulas:
F = u/(gy)^1/2
V = (β - 1)F
ν_k = (uy)/(2S_o)
ν_d = ν_k (1 - V²)

OUTPUT:

Froude number F : 0
Vedernikov number V : 0
Kinematic hydraulic diffusivity ν_k : 0
Dynamic hydraulic diffusivity ν_d : 0

Reference: The dynamic hydraulic diffusivity reexamined.
