Rouse number
The
Rouse number
(
P
or
Z
) 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. It is a ratio between the sediment
fall velocity
and the upwards velocity on the grain as a product of the
von Kármán constant
and the
shear velocity
.
