Retention basin. A retention basin, sometimes called a retention pond, wet detention basin, or storm water management pond (SWMP), is an artificial pond with vegetation around the perimeter and a permanent pool of water in its design. [1][2][3] It is used to manage stormwater runoff, for protection against flooding, for erosion control, and to ...
A constructed wetland is an artificial wetland to treat sewage, greywater, stormwater runoff or industrial wastewater. [1][2] It may also be designed for land reclamation after mining, or as a mitigation step for natural areas lost to land development. Constructed wetlands are engineered systems that use the natural functions of vegetation ...
A stormwater detention system during installation beneath a parking lot. A stormwater detention vault is an underground structure designed to manage excess stormwater runoff on a developed site, often in an urban setting. This type of best management practice may be selected when there is insufficient space on the site to infiltrate the runoff ...
Rain gardens, also called bioretention facilities, are one of a variety of practices designed to increase rain runoff reabsorption by the soil. They can also be used to treat polluted stormwater runoff. Rain gardens are designed landscape sites that reduce the flow rate, total quantity, and pollutant load of runoff from impervious urban areas ...
A settling basin, settling pond or decant pond is an earthen or concrete structure using sedimentation to remove settleable matter and turbidity from wastewater. The basins are used to control water pollution in diverse industries such as agriculture, [1] aquaculture, [2] and mining. [3][4] Turbidity is an optical property of water caused by ...
Bolsa Chica State Ecological Reserve is a natural reserve and public land in Orange County, governed by the state of California, and immediately adjacent to the city of Huntington Beach, California. [2] The reserve is designated by the California Department of Fish and Wildlife (CDFW) to protect a coastal wetland and upland, with both migratory ...
Bioswale. Runoff from the vicinity flows into an adjacent bioswale. Bioswales are channels designed to concentrate and convey stormwater runoff while removing debris and pollution. Bioswales can also be beneficial in recharging groundwater. Bioswales are typically vegetated, mulched, or xeriscaped. [1] They consist of a swaled drainage course ...
A wetland (aerial view) Wetland conservation is aimed at protecting and preserving areas of land including marshes, swamps, bogs, and fens that are covered by water seasonally or permanently due to a variety of threats from both natural and anthropogenic hazards. Some examples of these hazards include habitat loss, pollution, and invasive species.
