Measured rates of sedimentation: What exactly are we

By itself, the term ‘rate of sedimentation’ means nothing more than the rate at which sedimentation takes place. It is accordingly a very general term, which must be used with care. Firstly, sedimentation must be given its full modern meaning; it is not Sedimentation rate may refer to: Sedimentation rate of particles in a liquid, described by Stokes' law.

Sedimentation

In geology, the term sedimentation is broadly applied to the entire range of processes that result in the formation of sedimentary rock, from initial formation of sediments by erosion of particles from rock outcrops, through sediment transport and settling, to the lithification of the sediments. However, the term is more particularly applied to the deposition of sediments, and in the strictest seSedimentation Rate. Usually the sedimentation rate is defined as: (sediment inflow sediment flushing dredging)/year/km2of catchment. From: Hydraulics of Open Channel Sedimentation Rate an overview ScienceDirect Topics

Present and Future Losses of Storage in Large Reservoirs Due to

Reservoir sedimentation is often seen as a site-specific process and is usually assessed at an individual reservoir level. At the same time, it takes place everywhere in the world.

Sediments, Facies Tracts, and Variations in Sedimentation Rates

Where the sedimentation rate of a facies cannot be determined, a rate considered representative of the facies is commonly used. Many efforts have been made to determine ‘‘representative’’ sedimentation rates of var-ious facies (e.g., Sadler 1981, 1994, 1999; Enos 1991; Bosscher and Schla-ger 1993; cf. Bruns and Hass 1999).The reported sedimentation rate data focussed on accumulation areas like the Norwegian Trough (Fig. 2). However, to be able to spatially predict sedimentation rates across the study site it is necessary to include data from areas of erosion and non-deposition, which predominate in the North Sea.BG Organic carbon densities and accumulation rates in surface
