Sediment basin definition

Sediment basin means a barrier or dam built across a waterway or at other suitable locations to retain rock, sand, gravel or silt or other materials.

Sediment basin means a basin created by the construction of a barrier, embankment, or dam across a drainageway or by excavation for the purpose of removing sediment from the water.

Sediment basin means a naturally occurring or constructed depression used for the sole purpose of capturing sediment during or after an earth change activity.

Sediment basin means a temporary basin consisting of an embankment constructed across a wet weather conveyance, or an excavation that creates a basin or by a combination of both. A sediment basin typically consists of a forebay cell, dam, impoundment, permanent pool, primary spillway, secondary or emergency spillway, and surface dewatering device. The size and shape of the basin depends on the location, size of drainage area, incoming runoff volume and peak flow, soil type and particle size, land cover, and receiving stream classification (i.e., impaired, HQ, or unimpaired).

Sediment basin means a depression formed from the construction of a barrier or dam built to retain sediment and debris.

Sediment basin means a temporary structure consisting of an earthen embankment, or embankment and excavated area, located in a suitable area to capture sediment-laden runoff from a construction site. A sediment basin reduces the energy of the water through extended detention (48 to 72 hours) to settle out the majority of the suspended solids and sediment and prevent sedimentation in waterways, culverts, streams and rivers. Sediment basins have both wet and dry storage space to enhance the trapping efficiency and are appropriate in drainage areas of five acres and greater.

Sediment basin means a water impoundment constructed to collect and store sediment and/or debris made by constructing a dam or embankment or by excavating a pit or dugout pond for water storage. Its purpose is:

Sediment basin means a barrier, dam or other suitable detention facility built across an area of waterflow to settle and retain sediment carried by runoff waters.
