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.

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 means a structure designed to mitigate, reduce or prevent the amount of soil that is being transported by runoff;

• Sediment trap design shall comply with ODNR’s Rainwater and Land Development Manual.

• Sediment trap - A device used to filter waterborne sediment running off disturbed areas.

• General soil typeTrap efficiency factorSandy1.0Silt loam0.9Clay0.8Equation 8–5 is used to express the average discharge rate as a function of the runoff volume and release time.Table 8–4 Sediment trap efficiency factor by general soil type The sediment dry density may be estimated from soil survey data.

• 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].

• Sediment traps only used for drainage areas of less than 5 acres● Sediment trap storage calculations, showing that 1800 ft3/ total acre draining to each trap is provided below the spillway● If trapping efficiency calculations are required for sediment traps, then provide peak outflow, qpo, calculations; the 10-year, 24-hour storm event for construction conditions cannot overtop the trap’s spillway● Drainage area map outlining the area draining to each basin/trap.

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.
