Aggregation and sedimentation of aqueous nanoscale zerovalent iron dispersions.
Environmental Science and Technology, 2007Nanoscale zerovalent iron (NZVI) rapidly transforms many environmental contaminants to benign products and is a promising in-situ remediation agent. To be effective, NZVI should form stable dispersions in water such that it can be delivered in water ...

Sediment Measurement Techniques: A. Fluvial Sediment [PDF]
Journal of the Hydraulics Division, 1969 A description is given of modern techniques and equipment used to plan and make sedimentation measurements on natural streams. First typical examples are given of sedimentation characteristics of streams such as distribution of sediment with distance above the bed, variation of concentration with time and position in the stream cross section for the ...

Sedimentation and sediment flow on inclined surfaces
Journal of Fluid Mechanics, 1990The 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

Sedimentation on mid-ocean sediment drifts
Geological Society, London, Special Publications, 1986Summary The paper reports results from DSDP Leg 94, where holes were drilled in the Feni and Gardar sediment drifts, with particular emphasis placed on studying sediment waves that ornament the surfaces of the drifts. The Feni Drift is a 1500–1700 m thick accumulation of sediment constructed on an early Eocene to late Oligocene ...

Recent sediments and sedimentation in the Inner Hebrides
Proceedings of the Royal Society of Edinburgh. Section B. Biology, 1983SynopsisLittle land-derived material currently reaches the sea. Inland deposits are dominantly organic, peat succeeding lacustrine diatomite. Marine sediments result from the wave and tidal current reworking of Pleistocene glacial debris, with an admixture of Holocene skeletal carbonate.

Bioturbation, sedimentation and sediment-water exchanges
Estuarine, Coastal and Shelf Science, 1989Abstract A number of pollutants are associated with the particulate matter in river, estuary and coastal environments. Following cessation of a contaminant discharge, a question sometimes arises as to what degree and over what time period deposited sediments may be a pollutant source to the indigenous water column.

Sedimentation of an ellipsoidal particle in narrow tubes
, 2014Sedimentation behaviours of an ellipsoidal particle in narrow and infinitely long tubes are studied by a multi-relaxation-time lattice Boltzmann method (LBM). In the present study, both circular and square tubes with 12/13 ⩽ D/A ⩽ 2.5 are considered with
