2023年2月15日 · Sediment traps and basins are very similar in their siting, sizing, and design, with sediment traps serving areas of five acres or less and basins handling larger areas. They represent one of the most effective and reliable measures for treating sediment-laden runoff from construction sites.

2023年2月14日 · Check dams are used to regulate flow velocities, reduce scour erosion, and trap small quantities of sediment along higher-risk ditches and channels that have slopes greater than 10 percent and soil types conducive to erosion (e.g., sandy/silty soils).

2023年2月15日 · In most applications, treatment occurs at or along the perimeter control device, e.g., silt fence, rock berm, and fiber log. Other applications may involve the use of perimeter control berms or ditches to direct sheet flows to a treatment area, such as a sediment trap, sediment basin, or other BMP.

2023年2月15日 · Rock berms make excellent sediment barriers and can also be used to direct runoff to temporary sediment traps. This newly constructed sediment trap with rock berm and stone scour pad is installed in a drainage swale.

2023年1月31日 · A silt fence is a sediment control practice that removes sediment both through settling in water held behind the fence and through filtration. Management practices at construction sites can be characterized as those intended to prevent erosion and those that control sediment loss from sheet runoff and concentrated flow discharges.

2023年2月15日 · Inlet protection in areas with only surface drainage ditches are usually protected by stabilization practices, perimeter controls, and sediment traps. Consider the following when evaluating the use of inlet protection for a site.

2023年1月17日 · Sediment removal in traps and basins can be improved through the use of in-basin flow baffles, silt fence partitioning, and increased sizing / flow path design. Sedimentation facilities are often used in conjunction with chemical treatment to remove flocculated soil particles prior to final discharge.

2023年2月15日 · Design so that drainage from the wheel wash area leads to a trap, silt fence, or other BMP for settling. Wash water migrating off the site will need to be treated to remove sediment (e.g., via a sediment trap, rock berm, or sediment pond) or recycled.
