Effect of Suspended-Sediment Concentration on Nitrification in River Water: Importance of Suspended Sediment−Water Interface

Environmental Science & Technology, 2009
High suspended sediment (SPS) concentrations exist in many Asian river systems. In this research, the effects of SPS concentration on nitrification in river water systems were studied. With orwithout introducing ammonium-oxidizing bacteria isolated from the water and sediment samples of the Yellow River, the microbially mediated nitrification rate ...

Suspended Sediment Mineralogy and the Nature of Suspended Sediment Particles in Stormflow of the Southern Piedmont of the USA

Water Resources Research, 2019
AbstractThe majority of annual sediment flux is transported during storm events in many watersheds across the world. Using X‐ray diffraction, we analyzed the mineralogy of grab samples of suspended sediment during different stages of storm hydrographs in the Southern Piedmont.

Suspended sediment concentrations under waves

Coastal Engineering, 1986
Abstract A predictive formula is derived for calculation of the magnitude of time-averaged suspended sediment concentrations under waves. By taking into account the effect of flow contraction near ripple crests, the formula applies equally well for rippled beds and sheet flow conditions.

Sediments Suspended in Stream Flow

Journal of the Hydraulics Division, 1980
The paper considers a stationary translational sediment carrying flow. Correlation with experimental data enables to single out reliable solutions from a number of “traditional” ones which are based on the concept of equality of moment transfer and sediment diffusion coefficients.

Nonequilibrium Transport of Suspended Sediment

Journal of the Hydraulics Division, 1970
The nonequilibrium transport of suspended sediment in an open channel is studied at an abrupt change from a nonerodible to an erodible bed. The convective-diffusion equation is solved for the case of constant velocity distribution and parabolic eddy diffusion coefficient. Diffusion in the direction of flow is neglected.

Stability of settling of suspended sediments

The Physics of Fluids, 1978
The solution to the equations of two-phase flow which describes hindered settling is unstable to small perturbations.

Suspended Matter and Sediment Transport

1993
In the aquatic environment contaminants are transported in solution and in particulate form. In the latter case they are present as colloids or adsorbed onto particles (trace metals, trace organic compounds) or as single particles (e.g., flyash, coal, cokes, colliery waste, organic waste).

Transportation of Suspended Sediment by Water

Transactions of the American Society of Civil Engineers, 1946
Measurements of the sediment and velocity distributions in a laboratory flume were made for various values of rate of flow, slope of channel, and size and amount of suspended load.
