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 fluxes were highest in summer, consistent with trends in upper water- column chlorophyll and primary production measurements.

• Sediment trap quantities will be measured by the actual number installed and accepted.Removal of trash that is not generated by construction activities will be measured by the actual number of hours that Contractor workers actively remove trash from the project.

• In some cases, this Supporting Action should be use in conjunction with a Swale (W5), Sediment trap (W6) or In-ditch wetland (W7) Supporting Action.

• Sediment trap samples were analyzed in 2018 for total solids, total organic carbon, particle size distribution, metals, and semi-volatile organic compounds.

• Sediment trap volumes and dimensions should be sized according to the criteria in Section 7D-1.

• Sediment trap analyses have shown that the vertical flux coming from the plume represents only one percent of the input from the river in the lobe zone (Rabouille et al., 2019).

• Sediment trap samples collected in 2005 to monitor stormwater inflow exceeded cap monitoring benchmarks for total PAHs, individual PAHs, and zinc.

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.
