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.

Transformation of benzonitriles in anaerobic sediment and in sediment extract
Environmental Toxicology and Chemistry, 1995Abstract Transformations of para-substituted benzonitriles in sediment and in sediment extract were studied. In raw anaerobic sediment, most of the benzonitriles were transformed to benzoic acids without benzamide intermediates. Very slow disappearance of benzonitrile in autoclave-sterilized sediment was explained by the chemical ...

The Journal of Architecture, 2010
This paper explores how architecture can embody the past. In the context of Berlin—the site of much prominent contemporary memorial architecture—it examines one project in detail: Reitermann and Sassenroth's widely overlooked Chapel of Reconciliation, completed in 2000. This building, I argue, demonstrates a distinctive and critically acute approach to

The Basic Nature of Carbonate Sediments and Sedimentation
2013Abstract The biological influence over the origin, distribution, composition, texture, and mineralogy of carbonate sediments is stressed. Environmental factors such as light, temperature, and water depth directly affect these biological processes. Abiotic carbonate precipitation is discussed.

Frozen sediments and previously-frozen sediments
Geological Society, London, Special Publications, 2011Abstract Frozen surficial sediments that are otherwise unconsolidated contain structures and characteristics that are different from those of the same sediments when in an unfrozen state. These differences are usually related to either the nature of the ice contained within the frozen sediment or to weathering processes and chemical ...
