The vertical structure of a steady horizontally uniform, sediment-stratified turbulent flow of finite depth is uniquely determined by 4 dimensionless parameters (Rouse number, relative friction velocity, sediment Richardson number, relative height). The solution to the appropriate boundary-value problem is expected to show the property of complete similarity in the sediment Richardson number because the characteristic value of the sediment Richardson number is orders of magnitude greater than those of the other dimensionless parameters. This hypothesis is confirmed under conditions which are typical of estuaries and shallow waters by results of numerical experiments obtained using a b-L turbulence model. These results clearly demonstrate the dependence of the vertical mean velocity shear and suspended sediment concentration on the Rouse number and the relative friction velocity.
