The Rouse Number calculator computes the Rouse Number as a function of the sediment fall velocity (ws), the eddy viscosity to diffusivity constant (beta), and the shear velocity (u*).

Rouse Number (P): The calculator returns the Rouse Number.
The Rouse Number is a non-dimensional number in fluid dynamics which is used to define a concentration profile of suspended sediment and which also determines how sediment will be transported in a flowing fluid. The formula for the Rouse Number is:
