Detention ponds that are designed to permanently retain some volume of water at all times are called retention basins. In its basic form, a detention basin is used to manage water quantity while having a limited effectiveness in protecting water quality, unless it includes a permanent pool feature. [1]
Storm water is typically channeled to a retention basin through a system of street and/or parking lot storm drains, and a network of drain channels or underground pipes.. The basins are designed to allow relatively large flows of water to enter, but discharges to receiving waters are limited by outlet structures that function only during very large storm eve
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 or build a surface facility such as a detention basin or retention basin .
Recently completed infiltration basin for stormwater collection. An infiltration basin (or recharge basin) is a form of engineered sump [1] or percolation pond [2] that is used to manage stormwater runoff, prevent flooding and downstream erosion, and improve water quality in an adjacent river, stream, lake or bay.
Priorslee Lake in Shropshire, England. Originally known locally as the Balancing Lake, it was created to manage water run-off from the roofs and streets of Priorslee.. A balancing lake (also flood basin) is a term used in the U.K. describing a retention basin used to control flooding by temporarily storing flood waters. [1]:
Retention basin, stormwater runoff to prevent flooding and downstream erosion which includes a permanent pool of water; Detention basin, a man-made basin used to temporarily store surplus water from rivers. Sedimentary basin (sedimentology), a low and usually sinking region that is filled with sediments from adjacent higher areas
Watershed delineation is the process of identifying the boundary of a watershed, also referred to as a catchment, drainage basin, or river basin.It is an important step in many areas of environmental science, engineering, and management, for example to study flooding, aquatic habitat, or water pollution.
Detention basins are designed for temporary capture of flood waters and do not allow for permanent pooling of water and therefore do not make viable or reliable sources of water storage. [7] Retention basins are similar to detention basins for flood control management, but are built for permanent pooling to control sediment and pollutants in ...
