A simple analytic expression for calculating fine suspended-sediment t
ransport rates is derived by assuming a parabolic distribution of eddy
viscosity, which results in a von Karman-Prandtl-type velocity profil
e, and Rouse's sediment-concentration profile. The resulting equation
for sediment transport rate requires a set of hydraulic conditions and
a reference sediment concentration. This expression is easy to use in
practical applications, and predicted transport rates compare favorab
ly with rates calculated from field measurements.
