Abstract |
Deposition of fine cohesive sediments in a turbulent flow field was studied in a system of a rotating annular channel and ring. The percentage of the total sediment that a given flow can maintain in suspension depends only on the bed shear stress and is independent of the initial sediment concentration. The percentage (C) of the depositable sediment deposited at time t has been found to vary with time according to the law C=a log t + b, where the coefficient a is independent of the flow conditions and sediment concentration, while the coefficient b is a function of the bed shear stress only. Both a and b depend on the physicochemical properties of the sediment and the water environment. Deposition rates are proportional to the depositable sediment concentration and inversely proportional to time. (Author) |

Deposition of fine cohesive sediments in a turbulent flow field was studied in a system of a rotating annular channel and ring. The percentage of the total sediment that a given flow can maintain in suspension depends only on the bed shear stress and is independent of the initial sediment concentration. The percentage (C) of the depositable sediment deposited at time t has been found to vary with time according to the law (C = alpha logt + beta), where the coefficient a is independent of the flow conditions and sediment concentration, while the coefficient b is a function of the bed shear stress only. Both a and b depend on the physiochemical properties of the sediment and the water environment. Deposition rates are proportional to the depositable sediment concentration and inversely proportional to time. |
