Predicting suspended sediment concentration from nephelometric turbidity in organic‐rich waters

Rivers Research and Applications: an international journal devoted to river research and management, 2018
Nephelometric turbidity is an optical index for the side scattering of light caused by fine particles suspended in water. When a mixed composition of suspended inorganic and organic materials, including dissolved organic material, is present, turbidity ...

Ratios of Total Suspended Solids to Suspended Sediment Concentrations by Particle Size

Journal of Environmental Engineering, 2011
Wet-sieving sand-sized particles from a whole storm-water sample before splitting the sample into laboratory-prepared containers can reduce bias and improve the precision of suspended-sediment concentrations (SSC). Wet-sieving, however, may alter concentrations of total suspended solids (TSS) because the analytical method used to determine TSS may not ...

Predicting suspended sediment concentration on continental shelves

Marine Geology, 1985
Field observations of the near-bottom suspended sediment concentration, current and wave at a depth of 90 m on the Washington Shelf and at a depth of 1.5 m on the coastal Beaufort Sea show that wave-induced oscillatory flow plays a dominant role in resuspending bottom sediment.

Tidal Characteristics of Suspended Sediment Concentrations

Journal of Hydraulic Engineering, 1997
Analytical theory is used to describe the tidal constituents generat~d in suspen~ed sediment con­ centrations of clay, silt, and sand eroded by M 2 and S2 tidal currents. The assocIated model mvolves only the fall velocity W" the vertical dispersion coefficient E (assumed constant), and wa~er depth.D.

Capacitance sensors for measuring suspended sediment concentration

CATENA, 2005
Abstract Measurements of suspended sediment concentration are of importance in soil erosion research and soil and water conservation practices and monitoring. A method of measuring sediment concentration with capacitance sensors was advanced in this study.

Suspended sediment concentration prediction by Geno-Kalman filtering

Expert Systems with Applications, 2010
More accurate prediction of suspended sediment concentration will likely lead to more economic hydraulic construction and provide a valuable basis for the optimum operation of water resources. The majority of past models have relied on simple regression analysis relating discharge to concentration.

Propeller Jet–Induced Suspended-Sediment Concentration

Journal of Hydraulic Engineering, 2016
AbstractWhen subjected to a strong swirling jet flow induced by a rotating ship’s propeller, the bed of a waterway may undergo significant changes. These changes will not only cause instability to quay structures and damage the protection work of the beds/banks of rivers and canals, but also resuspend the bed sediment.

Suspended sediment concentration and the ripple–dune transition

Hydrological Processes, 2004
AbstractFlume experiments were conducted in order to monitor changes in flow turbulence intensity and suspended sediment concentration at seven stages across the ripple–dune transition and at three different positions above the bed surface. Three‐dimensional velocity measurements were obtained using an acoustic Doppler velocimeter (ADV).

Identification of Suspended Sediment Concentration in Stream Network

Applied Mechanics and Materials, 2016
Two series of suspended sediment concentration measurement within a stream network carried out during the dry and rainy season are presented in this paper. Information on suspended sediment concentration obtained from measurement are plotted on the map of stream network to allow a comparison between designated rivers..

Modelling Suspended Sediment Concentrations in the Firth of Forth

Estuarine, Coastal and Shelf Science, 1998
A two-dimensional depth-integrated sediment transport model has been applied to the Firth of Forth to study the resuspension and movement of sediment in the lower estuary. The dominant particle size in the region is 10 μm with about 70% of the near-bed particles and over 90% of the surface particles being in the size range 0–15 μm.
