Sediment trap definition

Sediment trap means a temporary impoundment built to retain sediment and debris which is formed by constructing an earthen embankment with a stone outlet.
Sample 1Sample 2Sample 3
Sediment trap means a temporary ponding area formed by constructing an embankment or excavation and embankment that will trap the flow of sediment-laden runoff. Sediment traps have a properly stabilized outlet/weir or riser and pipe to detain sediment laden runoff from disturbed areas of five acres or less. Outlets must be designed to extend the detention time and allow the majority of the sediment to settle out.

  • Sediment trap quantities will be measured by the actual number installed and accepted.

  • Sediment trap studies show that the flux of biogenic barite (i.e., barite in excess of terrigenous supply) is directly related to the flux of organic carbon [Dymond et al., 1992; Eagle et al., 2003]; thus, barite accumulation rates in pelagic sediments are thought to be a good proxy for export productivity [e.g., Erhardt et al., 2013, and references therein].

More Definitions of Sediment trap

Sediment trap means a temporary ponding area formed by constructing an embankment or excavation and embankment that will trap the flow of sediment-laden runoff. Sediment traps have a properly stabilized outlet/weir or riser and pipe to detain sediment-laden runoff from small disturbed areas of five acres or less. Outlets must be designed to extend the detention time allow the majority of the sediment to settle out. "Sinkhole" means a depression in the land surface formed by solution or collapse that directs surface runoff into subsurface or to an underground drainage flow.
