Sedimentation and sediment flow on inclined surfaces

Journal of Fluid Mechanics, 1990
The steady sedimentation of a suspension over an inclined surface is analysed by considering the combined effects of settling hindrance, bulk motion and particle resuspension. The coupled momentum and mass balances suggest that a thin high-density sediment layer will form over the inclined surface, reminiscent of the thin thermal boundary layers in the

Surface Selective Withdrawal in Sedimentation Basins

ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, 1984
AbstractBy employing the theory of propagation of columnar disturbance, general criteria for selective withdrawal in sedimentation basins are derived. The stratified fluid is assumed to be two‐layered with different density distribution in each layer. The effects of a free surface are also included in the analysis, but the viscosity is neglected as in ...

Polychlorinated biphenyls in Narragansett Bay surface sediments

Chemosphere, 2004
Polychlorinated biphenyls (PCBs) were evaluated in 41 surface sediments collected from Narragansett Bay, RI in 1997-1998. Highest concentrations of total PCBs (1760 ng/g) were in rivers at the head of the bay and the values decreased southward toward the mouth of the bay, with elevated concentrations in some of the coves.

Shear wave velocity in surface sediments

Jökull, 2011
Surface sediments of different nature are common in Iceland. Natural soil sites and man-made fillings commonly serve as foundations for different types of structures. In Civil engineering work it is fundamental to know the geotechnical properties of these materials in the upper 20–30 m.
